Description

  The present invention relates to an operation control device, an operation control method, and a program for operating, for example, equipment.

The maximum value of demand power (for example, average power of 30 minutes) in the power consumer is called demand, and contract power for the power company of the power consumer is determined based on this demand.
Of the power charges, the basic charge is determined by the contract power. Therefore, from an economical viewpoint, demand monitoring and control for adjusting the demand power so as not to exceed the contract power is generally performed.
In addition, a mechanism that encourages power demand adjustment based on information from the power system, such as increasing the unit price of power charges during specific seasons and time periods, such as during peak power hours, and discounting the power charges for consumers who have made certain power reductions There is. Such adjustment of power demand is called demand response.

Planned demand response control and real-time demand response control are known as functions of an operation management apparatus that executes such demand response (for example, Patent Document 1).
Planned demand response control is based on weather forecasts and past operation results, while controlling the power consumption in a specific time zone to a target value or less, while making facility equipment operation plans that do not sacrifice comfort in buildings as much as possible. Is to be operated according to the created operation plan.
In real-time demand response control, demand power is monitored even during planned operation, and when a situation in which demand power is likely to exceed a target value is detected, operation is performed so as to suppress the demand power below the target value.

JP 2012-80679 A

  The priority order set for equipment that is restricted in operation in the real-time demand response as described above is, for example, the past usage record of the space in which each equipment is used or the presence of people. It is set in advance with consideration. In other words, when setting the above priority order, for example, even if a real-time demand response is activated, consideration is given so as not to lose the comfort and convenience of the residents in the facility as much as possible.

  However, for example, the usage status of the space in the facility may vary greatly depending on the time and date. Therefore, for example, for a certain equipment, the priority order of operation restrictions in real-time demand response should be set low under normal use conditions. There may be a situation where there is no particular problem even if the operation is restricted by setting it high.

As an example, considering that air conditioning equipment such as conference halls are often used by outpatients, it is appropriate to set the priority order of operation restrictions in real-time demand response to be low. .
However, in such a hall, for example, a situation in which a person is absent tends to occur even during a period in which the use is reserved. In consideration of such a situation, for example, it is preferable that operation restrictions such as lowering or stopping the operation rate of the air conditioner can be given when there is no person in the conference hall during the real-time demand response. . As a result, for example, although there is a person in a space where a certain air conditioner is arranged, the priority set for the air conditioner is high, and thus operation restriction is performed by real-time demand response. This is because it is possible to avoid a situation where the comfort and convenience of the resident are impaired.
However, in Patent Document 1, the operation of facility equipment is restricted according to a predetermined priority order. For this reason, as described above, it is difficult to perform the operation restriction according to this even in the situation where the operation of the equipment with low priority can be restricted.

  In view of the above-described problems, an object of the present invention is to make it possible to flexibly set facility equipment that is subject to operation restriction upon demand response according to the state of a space where the equipment is installed.

  In order to solve the above-described problem, the operation control apparatus according to one aspect of the present invention associates the operation restriction contents of the operation restriction device, which is a facility device subject to operation restriction when reducing the demand power, with the priority order. The operation restriction device table storage unit for storing the operation restriction device table, and the operation restriction contents according to the priority order indicated by the operation restriction device table until reaching the power reduction amount necessary to make the purchased power equal to or less than the target value. Based on an operation control unit that controls the operation restriction device, a person presence state determination unit that determines the presence state of a person in a space in which the operation restriction device is provided, and the presence state of the person determined by the person presence state determination unit And a priority changing unit that changes the priority in the operation restricted device table.

  Further, in the operation control device of the present invention, the priority order changing unit changes the priority order when a state determined to be the presence state of the person whose priority order should be changed has passed a certain waiting time. The priority associated with the operation restriction content of the operation restriction device installed in the space determined to be the presence state of the person to be may be changed.

  Further, in the operation control device of the present invention, the priority order changing unit changes the priority order associated with a plurality of operation restriction contents having different restriction strengths for the same operation restriction device in the operation restriction device table. A different waiting time is set for each of a plurality of driving restriction contents, and when one of the different waiting times has passed that is determined to be the presence of a person whose priority should be changed, the time has passed. You may change the priority order matched with the driving | running | working restriction content in which standby time was set.

  In the operation control device of the present invention, a priority value associated with each operation restriction content in the operation restriction device table is defined as a specified value, and the priority change unit is configured to operate a plurality of different operation restriction devices. When changing the priority order associated with the restriction contents, the priority relation of the prescribed values may be reflected in the priority relation between the operation restriction contents.

  Moreover, the operation control method as one aspect of the present invention is a facility device that is subject to operation restriction when reducing demand power until reaching a power reduction amount necessary to make the purchased power equal to or less than a target value. An operation control step of controlling the operation restriction device according to the operation restriction content according to the priority order indicated by the operation restriction device table stored in the operation restriction device table storage unit in association with the operation restriction content of the operation restriction device with the priority order, and the operation Based on the person presence status determination step for determining the presence status of the person in the space where the restricted device is provided and the person presence status determined by the person presence status determination step, the priority order in the operation restricted device table is changed. A priority changing step.

  In addition, the program as one aspect of the present invention is a facility device that is subject to operation restrictions when reducing demand power until the computer reaches a power reduction amount necessary to reduce the purchased power to a target value or less. An operation control step for controlling the operation restriction device according to the operation restriction content according to the priority order indicated by the operation restriction device table stored in the operation restriction device table storage unit in association with the operation restriction content of a certain operation restriction device, and The priority order in the operation restriction device table is changed based on the person presence situation determination step for determining the presence situation of the person in the space where the operation restriction device is provided, and the person presence situation determined by the person presence situation determination step. For executing the priority order changing step.

  As described above, according to the present invention, it is possible to flexibly set facility equipment that is subject to operation restriction upon demand response according to the state of the space where the equipment is installed.

FIG. 1 shows a configuration example of a power management system according to an embodiment of the present invention.
The power management system shown in this figure includes an operation control device 100 and a plurality of facility devices 200.
The operation control apparatus 100 performs operation control on the equipment 200.
The customer of the facility equipped with the power management system of the present embodiment has, for example, contract power determined with an electric power company. In response to this, the power management system of the present embodiment uses the contract power for the contract power. The equipment 200 is operated so as not to exceed. The power used is the power used by the consumers as seen from the power company side, and is equal to the purchased power.
In addition, the power management system of the present embodiment performs an operation that does not exceed the upper limit value when the upper limit value of power consumption is set separately at a specific time and time zone, When set separately, operation control as a demand response is executed, such as an operation that minimizes the cost.

  Although illustration is omitted here, the power management system may include a power generation device using natural energy such as a solar cell or wind power generation, a fuel cell, a storage battery, or the like as a power source.

For example, one or more facility devices 200 are provided in each of the plurality of spaces 400-1 to 400-n.
Each of the spaces 400-1 to 400-n is provided in a facility where the power management system of the present embodiment performs power management. Each of these spaces 400-1 to 400-n is, for example, a room, a hall, a floor, or the like in a facility.
In the following description, the spaces 400-1 to 400-n are described as the space 400 unless otherwise distinguished.

Further, a human detector 300 is provided in each of the spaces 400-1 to 400-n.
The human detector 300 detects the presence of a person in the space 400 in which the person detector 300 is provided. The human detector 300 according to the present embodiment has a function of detecting, for example, the presence / absence of a person in the space 400 in which the person is present in the space 400 in which the person is provided.

For example, a human sensor using infrared rays can be adopted as the human detector 300. Alternatively, an IC card reader may be provided as the human detector 300 after an resident of the facility carries an IC (Integrated Circuit) card. In this case, information about the presence or absence of a person in each space 400 can be acquired by combining with an operation in which an IC card is read by an IC card reader when entering or leaving the space 400.
Alternatively, an RFID tag may be carried by a resident of the facility, and a reader corresponding to an RFID (Radio Frequency IDentification) tag may be provided as the human detector 300. Information on the presence or absence of a person in each space 400 can be acquired based on whether or not the RFID tag is detected by a reader compatible with the RFID tag.
Alternatively, a resident PHS (Personal Handy-phone System) may be carried by a resident of the facility, and a relay station or base station communicating with the PHS may be provided as the human detector 300. In the case of this configuration, by extracting information indicating which PHS is connected to which base station from the PHS switch, it is possible to acquire information on the presence or absence of a person in each space 400.
Alternatively, after carrying a portable terminal such as a smartphone of a resident of the facility, an application having a location information acquisition and notification function by GPS (Global Positioning System) or wireless LAN (WiFi) is enabled on the smartphone. It will be in the state. Under this state, information on the presence or absence of a person in each space 400 can be acquired by associating the location information of the mobile terminal with the space 400.

Next, a configuration example of the operation control apparatus 100 will be described with reference to the same FIG.
1 includes an operation plan creation unit 101, an operation plan creation data storage unit 102, a planned demand response (DR) compatible operation plan creation unit 103, an operation control unit 104, an operation restriction device table storage unit 105, A human presence state determination unit 106 and a priority order changing unit 107 are provided.

The operation plan creation unit 101 creates an operation plan for operating the equipment 200 in the facility. For example, the operation plan creation unit 101 creates an operation plan for the current day (for a period from the operation plan creation time to 24 hours ahead) at a predetermined operation plan creation time on the day (for example, a predetermined time in the morning, noon, etc.). create.
The operation plan creation unit 101 uses the operation plan creation data stored in the operation plan creation data storage unit 102 when creating the operation plan.

The operation plan creation data storage unit 102 stores operation plan creation data.
The operation plan creation data is predicted by patterning, for example, weather forecast data, power consumption result data indicating past power consumption results, and power consumed by the load as the equipment 200 in one day according to time zones. Load pattern data, etc.
In addition, when a power generation device or a storage battery is provided, data indicating specifications of the power generation device or the storage battery is also included.

The operation plan creation unit 101 uses these operation plan creation data, the load power amount required by the facility device 200 at a certain time interval on the day, the power generation amount of the natural energy generator, the storage battery Estimate the chargeable capacity, dischargeable capacity, etc. In addition, the operation plan creation unit 101 creates an operation plan of the equipment 200 that is optimized so that, for example, the purchased power is minimized based on these prediction results.
The purchased power is also called receiving point power, which is the power obtained by subtracting the output of the power supply device from the power consumption if the facility has a power supply device, and the power consumption if the facility does not have a power supply device. Is equal to

For example, when the predicted value for power demand is less than the power purchase power upper limit value, the operation plan creation unit 101 calculates power purchase power corresponding to the difference between the predicted value for power demand and the power purchase power upper limit value. Create an operation plan for charging a storage battery.
The demand power is power consumption consumed by the load facility.
The power purchase power upper limit value is an upper limit value of power purchase power that is determined based on contracted power and the like and should be protected so as not to be exceeded throughout the period.
In addition, when the predicted value for the demand power exceeds the power purchase power upper limit value, the operation plan creation unit 101 supplies the power that can be supplied from the power generation device or the storage battery, and suppresses the demand power. An operation plan with the correct content.
Hereinafter, the operation control performed by the operation control unit 104 in accordance with the operation plan created by the operation plan creation unit 101 is referred to as normal operation control.

The operation plan created by the operation plan creation unit 101 as described above is created so that the purchased power is minimized in order to cover the predicted load power amount. For this reason, the maximum value of the purchased power predicted under the operation plan is not necessarily equal to or lower than the purchased power upper limit value.
For this reason, when the maximum value of the purchased power (predicted purchased power value) predicted under the operation plan exceeds the purchased power upper limit value, the operation control unit 104 determines the planned demand response from the normal operation control. Switch to the operation control.

The planned DR corresponding operation plan creation unit 103 creates an operation plan corresponding to the planned demand response in response to the execution of the planned demand response as described above.
In the planned demand response, for example, an operation is performed so that the operation time of a specific facility device 200 is shifted in correspondence with a time zone in which the demand power is predicted to reach a peak.
As an example, the planned DR-compatible operation plan creation unit 103 causes a specific air conditioner, which is one of the facility devices 200, to be operated fully open for a certain period of time immediately before the time zone in which the demand power is predicted to peak. Next, in a time zone in which the demand power is predicted to reach a peak, the operation of the air conditioner is limited to be stopped or suppressed.
When operated in this way, air conditioning is sufficiently effective until just before the time when demand power is expected to reach its peak. Even if the driving is restricted, it is difficult for residents to feel uncomfortable.
The planned DR corresponding operation plan creation unit 103 creates an operation plan in which the operation time of the specific equipment device 200 is shifted as described above, for example, in response to the planned demand response.

When the predicted value for the purchased power does not exceed the purchased power target value, the operation control unit 104 controls the facility device 200 according to the operation plan created in advance. The purchased power target value is a target value of purchased power in each demand time period that is calculated by the control system (operation control device 100) from the prediction result of the load. The operation plan created in advance here is an operation plan corresponding to normal operation control created by the operation plan creation unit 101 and a plan demand response correspondence created by the plan DR correspondence operation plan creation unit 103. It is an operation plan.
Moreover, the operation control part 104 performs a real-time demand response, when the predicted value about purchased electric power exceeds the purchased electric power target value. The operation control unit 104 operates as a real-time demand response until the power reduction amount necessary for setting the predicted value of purchased power to be equal to or less than the purchased power target value is reached. To control the operation-restricted equipment according to

The operation control unit 104 determines which of normal operation control, planned demand response, and real-time demand response should be executed.
In this determination, the operation control unit 104 determines the maximum power purchase power (predicted power purchase value) and the power purchase power upper limit predicted under the operation plan corresponding to the normal operation control during execution of the normal operation control. Compare the value.
When the power purchase power predicted value is equal to or less than the power purchase power upper limit value, the operation control unit 104 determines that normal operation control should be continued. On the other hand, when the power purchase predicted value exceeds the power purchase upper limit, the operation control unit 104 determines that the planned demand response should be executed.

  In response to the determination that the operation control unit 104 should execute the planned demand response, the planned DR-compatible operation plan creation unit 103 creates an operation plan corresponding to the planned demand response. Then, the operation control unit 104 performs operation control as a planned demand response by operating the facility device 200 according to the generated operation plan corresponding to the planned demand response.

  In addition, the operation control unit 104 constantly monitors the purchased power. Then, the operation control unit 104 determines that the real-time demand response should be executed when the predicted purchased power value based on the monitored purchased power exceeds the purchased power target value.

When it is determined that the real-time demand response should be executed, the operation control unit 104 refers to the operation restriction device table stored in the operation restriction device table storage unit 105.
FIG. 2 shows an example of the contents of the operation restriction device table stored in the operation restriction device table storage unit 105.
As shown in this figure, the operation restriction device table has a structure in which operation restriction contents of operation restriction devices, which are equipment devices subject to operation restriction, are stored in association with each other in order of priority in order to reduce power demand.
Further, in the operation restriction device table shown in this figure, the power reduction amount, the operation status, and the cumulative reduction amount are stored in association with each other for the operation restriction contents.

The priority order indicates a priority order for performing the operation restriction for the equipment device 200 (operation restriction device) subject to the operation restriction during the real-time demand response.
The operation restriction content indicates the operation restriction device subject to the operation restriction, the space in which the operation restriction device is provided, and the content of the operation restriction for the operation restriction device. It should be noted that the operation restriction device included in the operation restriction content, the operation restriction device, the space in which the operation restriction device is provided, and the operation restriction content for the operation restriction device are individually operated as items. It may be stored in the restricted device table.
The power reduction amount indicates the power reduced by performing the operation restriction indicated by the corresponding operation restriction content.

The control availability indicates whether or not the operation restriction device indicated in the corresponding operation restriction content can be controlled for operation restriction under real-time demand response. For example, the operation-restricted device may be stopped due to manual operation or other factors regardless of the real-time demand response due to administrative reasons. Since such an operation restriction device has already stopped when executing the real-time demand response, it cannot be a control target of the operation restriction. Therefore, “impossible” is stored in the item of control permission / inhibition corresponding to the operation restriction contents for such operation restriction devices.
On the other hand, for example, “Yes” is stored in the control availability item corresponding to the operation restriction content of the operation restriction device that is being operated when shifting to the real-time demand response and can be the operation restriction control target. .
When the real time demand response is executed, the operation control unit 104 excludes the operation restriction contents in which the control availability is “impossible” from the operation restriction control targets.

  The cumulative reduction amount indicates the cumulative amount of power reduction in each priority order when operation control is performed according to the operation restriction contents according to the priority order. Since the cumulative reduction amount is obtained by adding the power reduction amount according to the priority order, it may be omitted from the operation restriction device table.

The operation control unit 104 operates in accordance with the order of priority until it reaches a power reduction amount (necessary power reduction amount) necessary to make the purchased power equal to or less than the target value (power purchase target value). The operation control indicated by is executed.
The power reduction required amount is a power value equal to or greater than a value obtained by subtracting the adjusted purchased power value from the current purchased power value. The adjusted power purchase value is the average value (predicted value) of the power purchased in the demand period including the present when the value is maintained from the present to the end of the demand period after the start of real-time demand response control. This is a power value that is less than or equal to the target value.
Since the purchased power value changes due to load fluctuations, the purchased power at the end of the demand time period is re-predicted at a relatively short period of about 1 minute, for example.
As a specific example, when the required power reduction amount is 18 kW, the operation control unit 104 executes a real-time demand response as follows. In other words, the operation control unit 104 executes operation control for stopping the external air conditioner, which is the operation restriction content associated with the priority order 10 in FIG. Further, operation control is performed to set the operation rate of the fourth-floor air conditioner fan, which is the operation restriction content associated with the priority 20 of FIG. 2, to 50%. Further, control for setting the operation rate of the fifth-floor air conditioner fan, which is the operation restriction content associated with the priority order 30 in FIG. 2, to 50% is executed.
The total power reduction amount (cumulative reduction amount) obtained by the above control is 20 kW, which is 2 kW more than the power reduction required amount of 18 kW. Thereby, the purchased power can be suppressed so as to be equal to or less than the purchased power target value.

  For example, even during execution of real-time demand response, the operation control unit 104 obtains a predicted power purchase value at the end of the demand time limit and compares it with the target power purchase value. And according to the electric power purchase electric power predicted value becoming below electric power purchase electric power target value, the operation control part 104 reduces the implementation item of the driving | running | working restriction content in real-time demand response control.

The person presence state determination unit 106 determines a person's presence state in the space 400 in which the facility device 200 as the operation restriction device is provided.
For this purpose, the human presence status determination unit 106 inputs detection information about the human presence status detected by the human detector 300 in the space 400 in which the equipment 200 as the operation restriction device is provided. Here, the person presence state determination unit 106 determines the presence or absence of a person as the person's presence state in the space 400.

The priority order changing unit 107 changes the priority order in the operation-restricted device table based on the presence state of the person determined by the person presence state determination unit 106.
For example, in the operation restriction device table, a priority order as a prescribed value is determined in advance. In addition, the priority changing unit 107 sets the priority in the operation restriction device table for the operation restriction contents of the equipment 200 provided in the space 400 that is determined by the person presence state determination unit 106 to have a person. The default value is left unchanged.
On the other hand, for the operation restriction contents of the equipment 200 provided in the space 400 determined that the person is not present by the person presence state determination unit 106, the priority order is set higher than the specified value. Change to

For example, if it is assumed that there is a person in a space such as a conference hall, it is preferable not to restrict driving by real-time demand response. The However, in the case of the present embodiment, even in such a space, when there is no person, the priority as a target of driving restriction by real-time demand response is raised. become.
For example, in real-time demand response so far, operation restrictions have been imposed according to a fixed priority order. In setting the priority order in this way, for example, considering the past achievements and the usage environment of the equipment, take into consideration not to impair the comfort and convenience of the resident as much as possible. Yes. However, since it is inevitable that the usage status of the space equipped with the equipment will change according to the time and date, it is possible to some extent that the comfort and convenience of residents will be reduced due to real-time demand response. It was recognized that there was no.
On the other hand, according to the present embodiment, for example, it is possible to perform the operation restriction by the real-time demand response while intensively selecting the facility device 200 in a space where no person exists. Thereby, it is possible to mitigate a decrease in the comfort and convenience of the resident while being a real-time demand response.

  Next, a specific example of priority change by the priority change unit 107 will be described with reference to FIG. 2 and FIGS. Here, a case will be described as an example where the first hall air conditioner indicated in the operation restriction contents associated with the priority orders 60 and 70 in FIG. In the description here, the operation restriction device table shown in FIG. 2 is the default content. That is, the priority for each operation restriction content shown in FIG. 2 is a specified value.

  In FIG. 3, about the determination result of the person presence condition determination part 106 about the presence condition of the person in the space 400 with which the equipment 200 as a 1st hall air conditioner is provided, and the operation restriction content about a 1st hall air conditioner The change in priority is shown over time.

In FIG. 3, time t1 to time t13 are a real-time demand response execution period Trdr in which a real-time demand response is executed.
Prior to time t1 when the real-time demand response execution period Trdr is started, the priority order of the operation restricted device table is in a state of a specified value. Here, before the time t1, the person presence state determination unit 106 does not exist (is absent).

For example, the priority changing unit 107 starts monitoring the determination result of the person presence state determining unit 106 in response to the time t1 when the real-time demand response execution period Trdr starts. At time t1, a situation where no person from before time t1 exists continues.
As described above, when starting from the situation where no person exists, the priority changing unit 107 does not immediately change the priority order at the time t1, but the situation where no person exists is the first standby. Wait to continue for time T1.
That is, the priority changing unit 107 according to the present embodiment obtains the determination result when a certain waiting time has elapsed for the determination result that the determination result that the priority should be changed is present. The priority order associated with the operation restriction content of the operation restriction device installed in the space 400 is changed.

In this case, even at the time t2 when the first waiting time T1 has elapsed from the time t1, the situation that no person from the time t1 exists continues. In this case, the priority order changing unit 107 changes the priority order of the operation restriction contents for the first hall air conditioner at time t2.
However, according to FIG. 2, there are two priority orders 60 and 70 as the operation restriction contents for the first hall air conditioner. The operation restriction content of the priority order 60 is to set the operation rate of the first hall air conditioner to 50%. On the other hand, the operation restriction content of the priority order 70 is that the operation rate of the first hall air conditioner is 0% (stopped), and the restriction strength is higher than that of the priority order 60. In the following description, the operation restriction content with priority 60 is referred to as the first-stage operation restriction content, and the operation restriction content with priority 70 is referred to as the second-stage operation restriction content.

As described above, when there are first-stage and second-stage operation restriction contents with different restriction strengths for the same operation-restricted device, the priority changing unit 107 waits for the first standby in a state where no person exists. As time T1 elapses, the priority of the first stage operation restriction content is first increased.
For example, the priority changing unit 107 changes the content of the operation restriction device table from the default content in FIG. 2 to the content in FIG. 4 at time t2.
In FIG. 4, the operation restriction content (first hall air conditioner: operation rate 50%), which was priority 60 in FIG. 2, has been changed to priority 5. In this case, the priority order 5 is the highest priority order in the operation restriction device table.

  Here, the priority order of the prescribed values shown in FIG. 2, FIG. 4 and the like is not an ascending order based on sequential numbers, but is an intermittent ascending order such as 10, 20, 30,. Thereby, when changing the priority order as shown in FIG. 4, it is only necessary to set the value of the priority order after the change between intermittent ascending order values. There is no need to raise or lower the value of.

  In addition, the priority changing unit 107 waits for a state in which no person exists from the time t1 to continue for the second standby time T2 after the time t2 when the priority order of the first stage operation restriction content is changed. To do.

However, in this case, the situation changes to a situation where a person is present at the time t3 before reaching the second standby time T2.
As described above, when the situation changes from a situation where no person is present to a situation where a person is present, the priority level changing unit 107 returns the priority order of the first stage operation restriction content to the specified value at the timing of time t3. . Thereby, the contents of the operation restriction device table are returned to FIG.
In this way, when the situation changes to a situation where there is a person, the priority is immediately returned to the specified value. Accordingly, the air conditioner can be started immediately at an operation rate of 100% in response to a person entering the first hall.

  Thereafter, at time t4, the situation where the person exists again changes from the situation where the person exists. Then, the priority changing unit 107 again determines the priority order of the first stage operation restriction content as the situation in which no person is present continues at time t5 when the first waiting time T1 has elapsed from time t4. Is changed as shown in FIG.

  Thereafter, at time t6 when the second waiting time T2 has not yet elapsed from time t4, the situation changes from a situation where no person is present to a situation where a person is present. In response to this, the priority changing unit 107 returns the priority of the first-stage operation restriction content to the specified value at time t6, similarly to time t3.

Thereafter, at time t7, the situation where a person is present is changed to a situation where no person is present, and the situation where no person is present continues at time t8 when the first waiting time T1 has elapsed since time t7. . Therefore, the priority changing unit 107 again increases the priority of the first stage operation restriction content at time t8. Thereby, the operation restriction device table is changed again to the contents shown in FIG.
In this case, even when the second standby time T2 has elapsed from the time t7 to the time t9, a situation in which no person from the time t7 exists continues. Therefore, the priority changing unit 107 further changes the priority of the operation restriction contents in the second stage so as to increase at time t9.

Thereby, the operation restriction device table is changed as shown in FIG.
In FIG. 5, the first stage operation restriction content (hall air conditioner: operation rate 50%) is given priority 5 and is the highest priority. Subsequent to this, the operation restriction content in the second stage is changed to the priority order 8 and to the second priority order.
As described above, when the situation in which no person exists continues for a certain long time, the content of the second stage operation restriction is also changed so as to increase the priority. That is, in such a situation, the degree of operation restriction of the first hall air conditioner is further increased with the expectation that a situation where no person exists for a certain long time will continue. Thereby, electric power reduction can be aimed at more efficiently.

Thereafter, at time t10, the situation changes from a situation where no person is present to a situation where a person is present. In response to this, the priority changing unit 107 returns the priority order to the specified value for the first stage operation restriction contents and the second stage operation restriction contents from the contents of changing the priority order as shown in FIG. Change to the default content of 2.
Thus, when it changes into the situation where a person exists, all the changed priorities are returned to a regulation value.

Thereafter, the situation changes to a situation where there is no person at time t11, and a situation where no person exists continues at time t12 when the first waiting time T1 has passed. Therefore, the priority order changing unit 107 changes the priority order of the first stage operation restriction content at time t12. As a result, the operation restriction device table is changed to the content shown in FIG.
Then, at time t13, the real-time demand response execution period Trdr ends. At time t13, a situation in which no person from time t11 exists continues, but the priority change unit 107 changes the first changed at time t12 at time t12 with the end of the real-time demand response execution period Trdr. Return the priority order of the operation restriction contents to the specified value.

The flowchart of FIG. 6 shows an example of a processing procedure executed by the operation control unit 104 in the operation control apparatus 100 of the present embodiment.
The operation control unit 104 follows either the normal operation control-compliant operation plan created by the operation plan creation unit 101 or the planned demand response-compliant operation plan created by the planned DR-compliant operation plan creation unit 103. Operation control is executed (step S101).

During the execution of the operation control in step S101 or the execution of real-time demand response control described later, the operation control unit 104 monitors the purchased power. The operation control unit 104 calculates a power purchase predicted value at the end of the demand time limit (for example, 30 minutes) based on the current power purchase power value (step S102). In addition, since the power of the load fluctuates sequentially, the process of step S102 is executed at a short cycle of, for example, 1 minute intervals.
Next, the operation control unit 104 compares the predicted purchased power value calculated in step S102 with the purchased power target value, and determines whether the predicted purchased power value exceeds the purchased power target value. (Step S103).
When the predicted purchased power value is less than or equal to the purchased power target value (step S103—NO), the operation control unit 104 returns to the process of step S101.

  On the other hand, when the power purchase power predicted value exceeds the power purchase power target value (step S103-YES), the operation control unit 104 calculates the power reduction required amount (step S104). For example, as the process in step S104, the operation control unit 104 calculates the adjusted purchased power value based on the current purchased power value, the purchased power target value, the remaining time until the end of the demand time limit, and the like. The operation control unit 104 obtains a necessary power reduction amount based on a value obtained by subtracting the adjusted purchased power value calculated from the current purchased power value.

Here, the priority changing unit 107 constantly monitors the determination result by the person presence state determination unit 106, and appropriately changes the operation restriction device according to the change in the determination result of the presence / absence of the person in the space 400. The priority order of operation-restricted devices in the table has been changed.
For example, the operation control unit 104 refers to the operation restriction device table subsequent to step S104 (step S105). As can be understood from the above description, the operation restriction device table indicates the priority order of each operation restriction device according to the presence state of the person in each current space 400. The operation control unit 104 executes operation control as a real-time demand response in accordance with the priority for each current operation restricted device shown in the operation restricted device table (step S106). That is, the operation control unit 104 restricts the operation of the facility device 200 according to the operation restriction content associated with each priority in the operation restricted device table so that the power reduction amount calculated in step S104 is obtained.
The processes in steps S104 to S106 corresponding to the real-time demand response control are repeatedly executed until it is determined in step S103 that the predicted power purchase value calculated in step S102 is equal to or less than the power purchase target value. The

  The flowchart of FIG. 7 shows an example of a processing procedure executed by the person presence status determination unit 106 and the priority order changing unit 107 regarding the change of the priority order of the operation restriction device table. The processing shown in this figure is executed regularly as described above. Moreover, the process shown to this figure is a process for the installation apparatus 200 as a certain one operation | movement restriction apparatus like the 1st hall air conditioner illustrated in FIGS. 2-5, for example.

  The human presence status determination unit 106 inputs detection information about the human status output from the human detector 300 provided in the space 400 including the facility device 200 as the operation restriction device (step S201). Next, based on the input detection information, the person presence status determination unit 106 determines the presence status (presence / absence of a person) of the person in the space 400 including the facility device 200 as the operation restriction device (step S202). .

The priority changing unit 107 determines whether or not the determination result in step S202 indicates that a person is present in the space 400 including the target operation-restricted device (step S203).
When the determination result indicates that a person is present (step S203—YES), the priority order changing unit 107 sets the priority order of the prescribed values for the operation restriction contents for the target operation restriction device (step S203). S204), the process returns to step S201.

On the other hand, if the determination result indicates that there is no person (NO in step S203), the priority changing unit 107 changes the priority order of the first-stage operation restriction content stored in the operation restriction device table. It is determined whether or not it has been completed (step S205).
In the case where the priority order of the first-stage operation restriction content has not been changed (step S205—NO), the priority order changing unit 107 will be described with reference to FIG. It is determined whether or not the first waiting time T1 has elapsed (step S207).

Here, when the duration of the state in which it is determined that there is no person has not yet passed the first waiting time T1 (step S207—NO), the priority changing unit 107 returns the process to step S201. .
On the other hand, when it is determined that there is no person after the second waiting time T2 has elapsed (step S207—YES), the priority changing unit 107 displays the first-stage operation restriction content in the operation restriction device table. The priority is changed so as to be increased to a predetermined value (step S208).

In addition, when the priority order of the first stage operation restriction content has been changed (step S205—YES), the priority order changing unit 107 further determines whether the second order operation restriction content priority has been changed. It is determined whether or not (step S206).
When the priority order of the second stage operation restriction content has been changed (step S206—YES), the priority order changing unit 107 returns the process to step S201.

On the other hand, when the priority order of the second stage operation restriction content has not been changed (NO in step S206), or after the priority order of the first stage operation restriction content is changed (step S208), the priority order changing unit 107 The following processing is executed.
That is, the priority changing unit 107 determines whether or not the state where it is determined that no person is present in step S201 continues even after the second standby time T2 described with reference to FIG. Step S209).
When it is determined that no person is present yet the second waiting time T2 has not yet elapsed (NO in step S209), the priority changing unit 107 returns the process to step S201.
On the other hand, when the state determined that there is no person has passed the second standby time T2 (step S209—YES), the priority changing unit 107 displays the second stage operation restriction content in the operation restriction device table. The priority is changed so as to increase to a predetermined value (step S210). Thereafter, the priority changing unit 107 returns the process to step S201.
As described above with reference to FIGS. 2 to 5, the priority order in the operation restriction device table is changed by the priority order changing unit 107 executing the process in this manner.

Hereinafter, various modifications of the present embodiment will be described.
The above description is an example of processing corresponding to the operation restriction content up to the second stage. For example, in the operation restriction device table, three or more levels of operation restriction contents may be stored for one operation restriction device. In addition, for example, the priority order may be changed for three or more operation restriction contents of one operation restriction device.
For example, if the operation restriction content of one operation restriction device is three stages, a third standby time longer than the second standby time is set in addition to the first standby time T1 and the second standby time T2. Then, when the third waiting time has passed while the situation where no person is present continues, the priority order of the operation restriction contents in the third stage may be changed.
Moreover, in the example of FIG. 5, it changed so that the priority of the operation | movement restriction content of the 2nd step about a 1st hall air conditioner may become high next to the operation restriction content of the 1st step | paragraph about a 1st hall air conditioner. However, for example, it is changed so that the priority order of the operation restriction contents of the other operation restriction devices is between the first stage operation restriction contents and the second stage operation restriction contents for the first hall air conditioner. May be.
Further, the standby time according to the stage of the operation restriction content as described above may be uniform with respect to the type of the operation restriction device, or a different time that is appropriate for each type of the operation restriction device. It may be set.

  Further, in the description so far, when the situation changes from a situation where no person exists to a situation where a person exists, the previously changed priority order is returned to the specified value. However, for example, when there is a change from a situation where there is no person to a situation where there is a person, instead of returning to the default value, for example, it is changed to a predetermined priority order lower than the priority order set so far. Also good.

In the description so far, the priority of the first stage operation restriction content is changed to the highest priority in the operation restriction device table in accordance with the change from the situation where there is a person to the situation where there is no person. doing. However, for example, the priority may be changed to a predetermined priority in the second and subsequent times.
In the operation restriction device table of FIG. 8, the priority changing unit 107 sets the priority order of the first stage operation restriction contents (first hall air conditioner: operation rate 50%) of the first hall air conditioner according to the above-described modification. A modified example is shown.
In the case of FIG. 8, for example, the operation restriction contents of the priority orders 10, 20, and 30 in the specified value are fixed to always give the highest priority, and the priority order is not changed. In addition, the first stage operation restriction content of the first hall air conditioner has a priority of “35”, and has been changed so that the priority is fourth in the operation restriction device table.

  In the description so far, the presence / absence of a person is determined as the presence state of the person in the space 400. For example, the number of persons in the space 400 may be determined. And the priority change part 107 may change the priority of the corresponding driving | running | working restriction content according to the number of persons. As an example, the priority changing unit 107 can change the priority so that the priority is increased as the number of people is reduced.

  Further, for example, it is determined whether or not the current user of the space 400 includes a guest as the presence status of the person, and the priority changing unit 107 changes the priority according to the determination result. May be. As an example, when the guest is not included, the priority changing unit 107 changes the priority as described with reference to FIG. On the other hand, when a guest is included, even if there is no situation in the space 400, the priority is not changed, or the priority is changed to a lower priority than when no guest is included. Is. Thereby, when the guest is included in the user of the space 400, the operation of the operation restriction device is maintained even in a situation where the person temporarily moves away from the space 400 and becomes absent. As a result, guests can avoid feeling discomfort and inconvenience.

In addition, for the purpose of making the explanation easy to understand, the priority order changing process for a certain operation-restricted device has been described so far. For example, under the present embodiment, the priority order can be changed for a plurality of different operation restriction devices in the operation restriction device table.
In this case, a state occurs in which the priority order of the operation restriction contents of a plurality of different operation restriction devices is changed in one operation restriction device table. At this time, for example, the priority relationship between the operation restriction contents of a plurality of different operation restriction devices is, for example, the relationship between the priority order of the prescribed values set for the operation restriction contents of the plurality of different operation restriction devices. Should be reflected.
As an example, the case where the operation restriction device A has a higher priority value of the operation restriction contents of the two operation restriction devices A and B will be described as an example. In this case, when the priority changing unit 107 changes the priority of the operation restriction contents of both the operation restriction device A and the operation restriction device B, the following is performed. That is, the priority changing unit 107 sets each priority so that the priority of the operation restriction content of the operation restriction device A is higher than the priority of the operation restriction content of the operation restriction device B according to the order of the specified values. change.

  In the description so far, the priority changing unit 107 changes the priority when the transition to the real-time demand response should be made. For example, the priority order of the operation restriction table may be changed at regular time intervals.

Some of the operation restriction devices start operation from a mid-day time according to a predetermined operation plan. In this case, for example, a situation may occur in which the operation-restricted device whose priority is to be changed at the current time is in a state immediately after the start of the operation. In this case, if the priority order is changed immediately, if the real-time demand response is activated shortly after the start of driving, the driving will be immediately restricted even though the driving has started. It will be a thing. For example, when the operation-restricted device is an air conditioner or the like, the room 400 of the space 400 approaches the set temperature when the operation is continued for a certain time from the start of the operation. Is not significantly impaired.
Therefore, when the operation restriction device indicated by the operation restriction contents to change the priority does not elapse for a certain period of time after starting the operation, the priority changing unit 107 elapses. The priority order may be changed after waiting.

  Further, for example, the operation restriction device shown in the operation restriction device table in FIG. 2 is an air conditioner related equipment device 200 such as an external air conditioner, an air conditioner, and a fan. Facility equipment may be included in the operation restriction equipment. Further, the air conditioner-related equipment may be intended not only for interpersonal air conditioning intended for people but also for so-called industrial air conditioning intended for articles and the like.

  Further, a program for realizing each functional unit in the operation control apparatus 100 shown in FIG. 1 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed. Thus, the priority order of the operation restricted device table may be changed. Here, the “computer system” includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Further, the “computer-readable recording medium” refers to a volatile memory (RAM) in a computer system that becomes a server or a client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. In addition, those holding programs for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention.
