(1) Overall Configuration of Energy Consumption Management System FIG. 1 is a schematic diagram for explaining an energy consumption management system according to an embodiment of the present invention. Hereinafter, for convenience of explanation, the energy consumed by the facility device 20 is assumed to be electric energy.

  The energy consumption management system is a mechanism that gives an incentive to a user of an equipment device when the equipment device 20 adjusts the energy consumption in response to a control request from the power company 1a for a predetermined adjustment period. . This energy consumption management system individually gives incentives to a plurality of users for a plurality of facility devices. The electric power company 1a and the user have concluded a contract in which an agreement regarding the use of electric power is determined in advance, and the incentive mode is also determined in advance based on the contract. Such an energy consumption management system is realized by the power supplier 1a of the power supplier and each device installed in each property A, B of the consumer.

  The power company 1 a has a power management device 10. The power management apparatus 10 sends a “control request” that prompts each facility device 20 to adjust energy. In addition, the power management apparatus 10 calculates the amount of incentive to be given to the user from the record that the facility device 20 responds to the control request. The power management apparatus 10 may be installed not only in the power company 1a but also in an aggregator that is a lower power supplier.

  The facilities 3a and 3b of the properties A and B are, for example, buildings such as office buildings, tenant buildings, factories, and general households. Each property A and B controls the equipment 20, the power supply 6 that supplies power to the equipment 20, the power meter 7 that measures the amount of power supplied from the power supply 6 to the equipment 20, and the equipment 20. The control device 30 is installed. Power is supplied from the power company 1a to the facilities 3a and 3b of the property A and B through the power line 102a. Electric power is supplied from the power source 6 to the equipment 20 in the same property via the indoor power line 102b. Moreover, the power management apparatus 10 and the control apparatus 30 are connected by the internet 101a, for example. The control device 30 and the equipment 20 in the same property are connected by a dedicated control line 101b or the like.

  In addition, in FIG. 1, although the number of each property A and B and each apparatus is described limitedly, it is not restricted to these numbers.

  As one aspect of the energy consumption management system described above, there is “demand response” (hereinafter sometimes referred to as “DR”), and energy adjustment control for realizing demand response is referred to as “demand response control”.

(2) Apparatus used for energy consumption management system (2-1) Power management apparatus 10
FIG. 2 is a schematic diagram illustrating the configuration of the power management apparatus 10. The power management apparatus 10 includes a communication unit 11, an input unit 12, an output unit 13, a storage unit 14, and a calculation unit 15.

  The communication unit 11 communicates with the control device 30 and includes a network interface that enables connection to the Internet 101a.

  The input unit 12 inputs information to the power management apparatus 10 and includes operation buttons, a keyboard, a mouse, and the like.

  The output unit 13 outputs information stored in the power management apparatus 10 and includes a display or the like.

  The storage unit 14 stores information and the like input to the power management apparatus 10 and includes a hard disk or the like. As shown in FIG. 3, the storage unit 14 stores a combination of an adjustable power amount and an adjustable time zone in each property A, B. The storage unit 14 stores a program executed by the calculation unit 15 and the like.

  The calculation unit 15 performs various calculations based on information stored in the power management apparatus 10 and includes a CPU, a ROM, a RAM, and the like. The calculation unit 15 reads and executes the program stored in the storage unit 14 to thereby execute the power consumption prediction unit 15a, the power adjustment determination unit 15b, the equipment device selection unit 15c, and the control shown in FIG. It functions as a request sending unit 15d and an incentive information determining unit 15e.

  The power consumption prediction unit 15a predicts the power supply amount and the demand amount, and predicts the power consumption after a predetermined time. The power consumption prediction unit 15a determines whether or not the demand amount of power after a predetermined time may exceed the predetermined supply amount.

  When the power consumption determining unit 15b determines that the power demand after a predetermined time may exceed the predetermined supply amount by the power consumption predicting unit 15a, the power adjustment determining unit 15b adjusts and adjusts the power consumption. The time and adjustment period are determined.

  The facility device selection unit 15c performs facility response control based on the information on the facility device 20 stored in the storage unit 14 and the information necessary for power consumption suppression determined by the power adjustment determination unit 15b. The device 20 is selected.

  The control request sending unit 15d sends a “control request” that prompts the control device 30 selected by the facility device selection unit 15c to adjust the power usage. The control request includes information such as the amount of power to be adjusted and the time zone. Depending on the contents of the contract between the power supplier and the power consumer, the amount of power to be adjusted may be determined in advance, and in this case, transmission of information regarding the amount of power to be adjusted is omitted.

  The incentive information determination unit 15e determines information regarding the amount of incentive given to the user. The amount of incentive is given by, for example, the product of the power adjustment amount and the incentive unit price. The incentive information determination unit 15e changes the incentive unit price or the like according to the situation.

(2-2) Equipment 20
The facility device 20 is a device that operates under the control conditions set by the control device 30. By operating the equipment 20 under control conditions that satisfy the control request from the power management apparatus 10, the power consumption is adjusted in the energy consumption management system.

  Examples of the equipment 20 include an air conditioner 20a, a lighting device 20b, and a ventilation fan 20c. The air conditioner 20a has different power consumption in the operation state depending on the difference in the operation mode such as the cooling mode / heating mode, the difference in the set temperature, and the environment such as the outside air temperature. Some of the lighting devices 20b are operated only on / off and consume a certain amount of power in the operating state, and some of the lighting devices 20b switch the illuminance in multiple stages and have different power consumption for each operation. The ventilation fan 20c is operated only on / off, and consumes a certain amount of power in the operating state.

(2-3) Control device 30
FIG. 4 is a schematic diagram illustrating the configuration of the control device 30. The control device 30 is used in the energy consumption management system and controls the equipment 20. The control device 30 includes a communication unit 31, an input unit 32, an output unit 33, a storage unit 34, a setting unit 35, a calculation unit 36, and a control unit 37. Here, the control device 30 (schedule creation device) creates a schedule relating to acceptance of demand response control executed by the equipment device 20.

  The communication unit 31 communicates with the power management apparatus 10 and includes a network interface that enables connection to the Internet 101a. Further, the communication unit 31 (incentive unit price information acquisition unit) acquires “incentive unit price information” set for each time period. Information on the incentive unit price acquired by the communication unit 31 is written in the storage unit 34 described later.

  The input unit 32 is used to input information to the control device 30, and includes an operation button and a touch screen that covers the display of the output unit 33. Via the input unit 32, various commands such as a change in setting for the equipment 20 and a change in operation mode can be input. The input unit 32 (acceptance condition accepting unit) accepts an accepting condition for accepting the control request in association with each time limit within a predetermined period. Furthermore, the input unit 32 accepts a setting of an allowable comfort amount indicating an allowable amount of comfort around the equipment. These acceptance conditions and the comfort allowance are written in the storage unit 34 to be described later. The “comfort allowable amount” is, for example, a comfort allowable temperature in a room. Here, the indoor minimum temperature or the indoor maximum temperature is set as the comfort allowable temperature. The acceptance conditions will be described later.

  The output unit 33 outputs information stored in the control device 30 and includes a display or the like. For example, the output unit 33 outputs a screen showing the operation mode of the facility device 20 to the display, and sets the ON / OFF of the facility device 20, the operation mode (for example, the cooling mode / heating mode for the air conditioner 20a), and the setting. It displays temperature, illuminance, ventilation volume, operating time, operating rate, other information related to operating capacity during operation, and current power consumption. Further, the output unit 33 displays the control result of the demand response control on the display. The output unit 33 outputs a schedule related to acceptance of demand response control in response to a user request.

  The storage unit 34 stores information input to the control device 30 and includes a hard disk or the like. The storage unit 34 stores a program that can be read and executed by the calculation unit 36 described later. Furthermore, the storage unit 34 stores information on control conditions and power consumption according to the type of the equipment device 20. The “control condition” is a condition when the control device 30 controls the equipment device 20. For example, as control conditions, output information for controlling the air conditioner 20a so as to reach a predetermined set temperature is stored. In the initial state, the control conditions are set in advance. In addition, the storage unit 34 stores the incentive unit price information acquired by the communication unit 31, the acceptance condition and the comfort allowance input by the input unit 32. Here, the acceptance conditions are stored in the acceptance condition storage area 34a of the storage unit 34 as shown in FIG. The “acceptance condition” defines, for example, whether or not to accept the acceptance lower limit unit price and the DR control in association with each time period (within a predetermined period) within one day. For example, in the example of FIG. 5, if the incentive unit price is equal to or higher than the acceptance lower limit unit price of X3 yen in the time period where the start time is 15:00 and the end time is 16:00, it is set to accept the execution of the DR control. Yes. In other words, in this time period, when the incentive unit price is less than the acceptance lower limit unit price X3 yen, the DR control is not performed. Further, when it is set that the DR control is not performed, the DR control is not performed regardless of the setting of the acceptance lower limit unit price. For example, in the example of FIG. 5, in the time period from 13:00 to 14:00, the DR control is not performed even if the incentive unit price is equal to or more than X3 yen, which is the acceptance lower limit unit price.

  The setting unit 35 sets control conditions for the equipment 20 based on information input from the input unit 32 and the like. The setting unit 35 sets control conditions for the equipment device 20 based on a schedule regarding acceptance of DR control, which is created by the calculation unit 36 described later. When the control condition of the demand response control is changed in the setting unit 35, the amount of incentive obtained based on the control result of the demand response control is changed.

  The computing unit 36 performs various computations based on information stored in the control device 30 and includes, for example, a CPU, a ROM, and a RAM. The function of the calculation unit 36 is realized by reading and executing the program stored in the storage unit 34 described above. The calculation unit 36 has a function of calculating the incentive acquisition amount based on the control condition set by the setting unit 35. In addition, the calculation unit 36 generates information to be output to the display of the output unit 33. Furthermore, the calculation part 36 (schedule creation part) creates the schedule regarding acceptance of DR control in each time limit within a predetermined period based on an incentive unit price, acceptance conditions, and comfort allowance. In addition, when the incentive unit price after the next time period changes within a predetermined period, the calculation unit 36 (schedule creation part) cancels the control content of demand response control for the current time period and recreates the schedule. The recreation of the schedule will be described later.

  The control unit 37 controls the equipment 20 based on the control conditions set by the setting unit 35.

(3) Schedule Creation in Control Device 30 (3-1) Flow of Schedule Creation Processing FIG. 6 is a flowchart for explaining schedule creation processing in the control device 30 according to the present embodiment. FIG. 7 is a diagram for explaining an example of a schedule creation process. For convenience of explanation, here, it is assumed that the equipment 20 is the air conditioner 20a, and the cooling operation by the air conditioner 20a is limited by the DR control.

  First, incentive unit price information is acquired via the communication unit 31 of the control device 30 (step S1). Here, it is assumed that the incentive unit price is set for each time period. For example, as shown in FIG. 7A, the incentive unit price in the time period from 15:00 to 16:00 and from 16:00 to 17:00 is all X4 yen.

  Subsequently, an “acceptance condition” for accepting the control request is set in the input unit 32 of the user by an operation or the like (step S2). Here, the acceptance condition is set in units of one day, and determines whether or not to accept the acceptance lower limit unit price and DR control for each time period. In the example of FIG. 7A, in each time period from 15:00 to 16:00 and from 16:00 to 17:00, it is set that DR control is performed if the incentive unit price is equal to or more than the accepted lower limit unit price X3 yen. ing.

  In addition, the comfort allowance is input by the user's operation of the input unit 32 or the like (step S3). In the example of FIG. 7A, the indoor maximum temperature is set to 28 ° C. as the comfort allowance. Therefore, the air conditioner 20a is controlled by the control device 30 so that the room temperature does not exceed 28 ° C.

  Then, based on the incentive unit price, the acceptance condition, and the comfort allowance, a “schedule” for setting whether to accept the DR control for each time period is created by the arithmetic unit 36 of the control device 30. (Step S4).

  Thereafter, as long as the incentive unit price does not change, the control device 30 performs DR control of the equipment 20 based on the schedule created in step S4 (steps S5-No, S6). In the example of FIG. 7A, the incentive unit price (X4 yen (X4> X3)) is higher than the acceptance lower limit unit price (X3 yen) in the time period from 15:00 to 16:00 and the time period from 16:00 to 17:00. The apparatus 30 performs DR control of the equipment 20 with the adjustment amount Y4.

  On the other hand, when the control device 30 acquires information indicating that the incentive unit price has changed via the communication unit 31 after creating the schedule, the calculation unit 36 of the control device 30 re-creates the schedule (step S5-Yes, S7). And the control apparatus 30 performs DR control of the equipment 20 based on the re-created schedule (step S6). Specifically, when the incentive unit price after the next time period changes, the calculation unit 36 of the control device 30 “stops” the control content of the DR control for the current time period and recreates the schedule. For example, as shown in FIG. 7B, the current time period is from 15:00 to 16:00, and the incentive unit price from 16:00 to 17:00, which is the next time period, has changed from X4 yen to X5 yen (X5> X4). In this case, the control device 30 recreates the schedule from 16:00 to 17:00, which is the next time limit. Here, the calculation unit 36 of the control device 30 has the maximum amount of incentives within the range in which the set temperature of the equipment device 20 does not exceed the indoor maximum temperature of 28 ° C. from 16:00 to 17:00, which is the next time limit. Such an adjustment amount Y5 is calculated. And the control part 37 of the control apparatus 30 performs DR control of the equipment 20 with the adjustment amount Y5.

(3-2) Schedule Recreation Processing Further explanation about schedule recreation processing will be added. As described above, it is assumed that the equipment 20 is the air conditioner 20a, and the cooling operation by the air conditioner 20a is limited by the DR control.

  FIG. 8 is a diagram for explaining the schedule re-creation process. Here, FIGS. 8A, 8B and 8C are respectively the start time t1 of the current time period JA, the time t2 when the incentive unit price has changed, and the start time of the next time period JB (= current time period). Is a graph showing changes in the integrated incentive amount, the DR control adjustment amount, and the indoor temperature (room temperature) at the end time t3 of the next time limit JB. Here, it is assumed that the incentive unit price for the current time period JA and the incentive unit price for the next time period JB were initially the same value, but the incentive unit price for the next time period JB was increased at time t2.

  In such a situation, as an example of the schedule re-creation process, the control device 30 controls the demand response control of the current time limit JA so that the upper limit of the allowable comfort amount is reached at the end time t4 of the next time limit JB. Cancel. Specifically, the control device 30 stops the DR control at time t2 when a change in the incentive unit price occurs. Thereby, the output of the air conditioner 20a increases and the room temperature decreases. Subsequently, the control device 30 resumes the DR control at the start time t3 of the next time period JB. Thereby, the output of the air conditioner 20a decreases and the room temperature increases. Further, when resuming the DR control, the control device 30 sets the adjustment amount of the DR control so that the indoor temperature reaches the indoor maximum temperature and the incentive acquisition amount becomes maximum at the end time t4 of the next time limit JB. Set.

  As a result, as shown in FIG. 8A, the accumulated amount of the incentive at the end time t4 of the next time limit JB is not recreated when the schedule is recreated (line I1) (line I2). ) Is a higher value. On the other hand, as shown in FIG. 8C, the room temperature at the end time t4 of the next time period has the same value when the schedule is recreated (line T1) and when the schedule is not recreated (line T2). .

  In short, as the schedule is recreated by the control device 30 according to the present embodiment, the amount of incentives to be acquired is increased as compared with the case where the schedule is not recreated. Even in such a case, the comfort at the end time t4 of the next time limit JB is maintained within a range that the user can withstand.

  Here, since the calculation unit 36 re-creates the schedule so as to stop the DR control at the time t2 when the incentive unit price has changed, it is possible to quickly bring the room temperature close to the set temperature, and at the next time limit JB. The adjustment amount of DR control can be increased.

  In this example, the case where the incentive unit price of the next time period JB is higher than the incentive unit price of the current time period JA has been explained. However, even if the incentive unit price of the next time period JB becomes lower, the schedule is recreated in the same way. Processing is executed. That is, when the incentive unit price of the next time period JB is high, the DR control of the current time period JA is stopped and the control amount of the DR control of the next time period JB is increased. When it becomes lower, the control amount of the DR control at the current time limit JA is increased, and the DR control at the next time limit JB is stopped. However, even in this case, the control amount of the DR control is set in a range that satisfies the comfort tolerance.

  In addition, although it demonstrated on the assumption that the cooling operation of the air conditioner 20a was carried out here, the same view is applied also in the case of heating operation. However, in the case of heating operation, DR control is executed such that the comfort allowance satisfies the indoor minimum temperature.

  Here, the air conditioner 20a has been described as an example of the equipment 20 but the equipment 20 according to the present embodiment is not limited to the air conditioner 20a as long as the comfort of the surrounding space is changed. For example, when the facility device 20 is a ventilation fan 20C, the comfort tolerance is set based on the ventilation amount and the CO2 concentration instead of the room temperature.

(4) Features (4-1)
As described above, the control device (schedule creation device) 30 according to the present embodiment provides the user of the facility device 20 with the demand response control that adjusts the energy consumption according to the control request. It is used for energy consumption management systems that give incentives. And the control apparatus 30 produces the schedule regarding acceptance of demand response control performed with the equipment 20. FIG. The control device 30 includes a communication unit 31 (incentive unit price information acquisition unit), an input unit 32 (acceptance condition reception unit), a storage unit 34 (comfort tolerance storage unit), and a calculation unit 36 (schedule creation unit). With. The communication unit 31 acquires incentive unit price information set for each time period. The input unit 32 receives an acceptance condition for accepting the control request in association with each time period within a predetermined period. The storage unit 34 stores an allowable comfort amount indicating an allowable amount of comfort around the equipment device 20. The computing unit 36 creates a schedule for each time period within a predetermined period based on the incentive unit price, the acceptance condition, and the comfort allowance.

  Therefore, the control device 30 creates a schedule for acceptance of demand response control in consideration of acceptance conditions and comfort allowance according to the information of the incentive unit price, so that consideration is given to comfort and incentive acquisition efficiency You can create a schedule that contributes to improving And since the control apparatus 30 controls the equipment 20 according to this schedule, the optimal demand response control with respect to the equipment 20 can be performed.

  In recent years, the home DR market has expanded, but many users in the home DR market do not have sufficient knowledge about air conditioning and power. And the subject that it is difficult for such a user to master the user interface of DR control is pointed out. In response to such a problem, the control device 30 according to the present embodiment automatically re-creates the schedule in real time and executes the optimum DR control based on the schedule, thereby reducing the load on the user.

(4-2)
Moreover, the control apparatus 30 which concerns on this embodiment recreates a schedule, when the calculating part 36 changes an incentive unit price within a predetermined period. Therefore, in this control device 30, when the incentive unit price changes, a schedule that matches the user needs is automatically re-created, so that it is possible to execute optimum demand response control while improving user convenience.

(4-3)
Further, in the control device 30 according to the present embodiment, when the incentive unit price after the next time period changes within a predetermined period, the calculation unit 36 cancels the control content of the demand response control for the current time period and schedules it. Recreate it. Therefore, in this control device 30, when the incentive unit price changes, the control content of the demand response control of the current time period is canceled, and the schedule taking into account the influence of the control content of the previous and subsequent time periods is automatically re-created. Demand response control can be executed.

  In particular, the control device 30 according to the present embodiment cancels the control content of the demand response control for the current time period and re-creates the schedule so that the upper limit of the allowable comfort amount is reached at the end of the next time period. Therefore, since this control device 30 automatically re-creates a schedule with high incentive acquisition efficiency while satisfying comfort, optimal demand response control can be executed.

(5) Modification (5-1) Modification 1A
When a change occurs in the incentive unit price, the calculation unit 36 of the control device 30 according to the present embodiment “stops” the DR control and recreates the schedule at the time t2 when the change occurs, but stops the DR control. Rather than “relaxing”, the schedule may be recreated.

  FIG. 9 is a diagram for explaining a schedule re-creation process in Modification 1A. Here, the graph of FIG. 9 is the same as the graph of FIG. 8, when the adjustment amount of DR control is relaxed (FIG. 9B), the integrated incentive amount (line I <b> 3 of FIG. 9A), and the room temperature (FIG. 9). The change of line T3) in (c) is added.

  In the present modification 1A, the incentive integrated amount (I3) and the room temperature value (T3) at time t4 are the same values as when the DR control is “stopped” and the schedule is recreated (I1, T1). However, since the control device 30 according to the present modification 1A “relaxes” the adjustment amount of the DR control and re-creates the schedule, it can execute the DR control so that the room temperature changes gradually. As a result, DR control considering user comfort can be executed.

  Note that the adjustment amount of the DR control is relaxed by, for example, holding the power value after relaxation as shown in FIG. 10A as table information, and setting an upper limit capacity value using the table value. The amount of increase in power after relaxation as shown in (b) is held as table information, and is relaxed by setting the amount of relaxation from the current value. Moreover, each value of the electric power after relaxation and the electric power increase after relaxation is calculated | required by learning from performance data, or calculating backward from catalog data.

  In the schedule re-creation process, whether to relax or cancel the DR control is determined according to the state at the time of the re-creation process. That is, when the room temperature is close to the set temperature, it is difficult to be uncomfortable even if the DR control adjustment amount is increased, but when the room temperature is far from the set temperature, the DR control adjustment amount is increased. There is a fear. Here, the relationship shown in FIG. 11 is established between the temperature and the adjustment amount during the schedule re-creation process. FIG. 11A shows the start time of the next time period JB when the incentive unit price changes at time t2 and the DR control is interrupted, relaxed, or continued at time t2 in the current time period JA. A deviation amount ΔT between the room temperature and the set temperature at t3 is shown. Here, the amount of deviation ΔT at the start time t3 of the next time period JB decreases in the order of interruption, relaxation, and continuation. Then, as shown in FIG. 11B, when the deviation amount ΔT between the room temperature and the set temperature at the time t2 of the schedule re-creation process is small, the adjustable amount at the start time t3 of the next time period JB increases. When the difference ΔT between the room temperature and the set temperature at the time t2 of the re-creation process is large, the adjustable amount at the start time t3 of the next time limit JB is small.

  Further, the relationship as shown in FIG. 12 is established between the deviation amount ΔT and the time ts required to reach the set temperature. That is, the larger the control amount of DR control, the shorter the time ts until reaching the set temperature. These pieces of information are learned from past operation results and stored in the storage unit 34 in the form of an internal table or the like.

(5-2) Modification 1B
When the change occurs in the incentive unit price, the calculation unit 36 of the control device 30 according to the present embodiment stops the DR control at “time t2” when the change occurs, and re-creates the schedule. The DR control may be stopped and the schedule may be recreated at “time t5” when the time has elapsed.

  FIG. 13 is a diagram for explaining a schedule re-creation process in Modification 1B. Here, the graph of FIG. 13 is obtained by adding the change of the accumulated incentive amount (line I4 in FIG. 13) when the DR control is stopped at time t5 (t5> t2) to the graph of FIG. 9A. is there.

  In the present modification 1B, by continuing the DR control in the current time period JA after time t2 until time t5, the accumulated amount of incentives can be maximized at the end time t4 of the next time period. That is, by delaying the stop of the DR control, a certain amount of adjustment is secured even in the current time period, and control for increasing the amount of incentive acquisition is performed. In addition, DR control is executed so as not to exceed the indoor maximum temperature even at the end time t4 of the next time limit.

  Note that the time t5 when the DR control is stopped is calculated backward from the time required until the room temperature reaches the set temperature after the DR control is stopped. That is, the remaining time tr in the current time period is compared with the required time ts until the room temperature reaches the set temperature after the DR control is stopped, and if the required time ts <the remaining time tr, the time is later than the time t2. By interrupting or mitigating the DR control from time t5, it is possible to increase the amount of incentives acquired while maintaining a comfortable comfort level. On the other hand, if the required time ts> the remaining time tr, the DR control is immediately interrupted or relaxed.

(5-3) Modification 1C
In this modification 1C, the equipment 20 is the air conditioner 20a, and the storage unit 34 of the control device 30 stores the past air conditioning load amount of the air conditioner 20a in each time period within a predetermined period, as shown in FIG. An air conditioning load storage area 34b is further provided. Then, when the calculation unit 36 compares in units of one day (within a predetermined period), if the air conditioning load amount of the current time period has changed from the past air conditioning load amount of the same time period, while maintaining comfort, Re-create the schedule to maximize incentive acquisition. For example, the calculation unit 36 normally executes DR control in the time period from 12:00 to 13:00, but when the DR control is suddenly stopped only on that day, the incentive accumulated amount on that day is not decreased. As described above, the schedule relating to acceptance of DR control for the remaining 13:00 to 24:00 is automatically recreated. Then, optimal demand response control is executed by following the re-created schedule.

  Note that the calculation unit 36 may re-create a schedule when the air conditioning load amount up to the present changes from the past air conditioning load amount when compared on a daily basis (within a predetermined period). For example, the calculation unit 36 normally executes DR control from 9 o'clock to 13 o'clock, but when the DR control is suddenly stopped only on that day, so as not to decrease the incentive accumulated amount on that day, A schedule relating to acceptance of DR control for the remaining time from 13:00 to 24:00 may be automatically recreated. In short, since the calculation unit 36 automatically re-creates the schedule according to the usage status of the user's air conditioner from the start of the day to the present, so that demand response control according to the operating status of the equipment can be executed. Become.

  When the comparison is made on a daily basis, the schedule is re-created by comparing, for example, the air-conditioning load amount for the day and the average value of the air-conditioning load amount for the past week.

(5-4) Modification 1D
The calculation unit 36 of the control device 30 according to the present embodiment executes schedule re-creation processing when the incentive unit price changes, but may re-create the schedule according to changes in external information other than the incentive unit price. .

  For example, as the external information other than the incentive unit price, predicted temperature information based on weather forecast data and the like can be cited. Then, the amount of temperature shift from the expected temperature is set as the comfort allowance. With this setting, assuming that the expected temperature is 22 ° C. and the shift amount is ± 3 ° C., if the room temperature is 26 ° C. (> 22 ° C. + 3 ° C.), it is considered that comfort is impaired. . In this case, the calculation unit 36 of the control device 30 executes the schedule re-creation process so that the comfort is enhanced by stopping or mitigating the DR control. And the control apparatus 30 performs the optimal demand response control with respect to the equipment 20 according to the re-created schedule.

(5-5) Modification 1E
In the present embodiment, schedule re-creation processing may be executed so that a target incentive amount for a predetermined period can be acquired. In this case, first, for example, a “target incentive amount” for one day is input via the input unit 32. Subsequently, the calculation unit 36 determines whether or not the target incentive can be acquired when the DR control is executed according to the existing schedule. If the target incentive amount is not reached even if the DR control is executed according to the existing schedule, the calculation unit 36 performs schedule re-creation processing. Specifically, the calculation unit 36 changes a time period set not to perform the DR control to a time period for performing the DR control so as to satisfy the target incentive, and extends the DR control period. Or the calculating part 36 further increases the control amount of the time limit set when implementing DR control. However, in any case, the DR control is executed in a range in which the comfort allowance is satisfied in the time period when the DR control is performed. In this way, the equipment device 20 is controlled by the control device 30 so that the target incentive is acquired.

(5-6) Modification 1F
In the present embodiment, the control amount of DR control is adjusted by stopping or mitigating, but the control amount of DR control may be adjusted by increasing or decreasing the number of facility devices 20. When the entire building is a control target, it may be easier to introduce the system by changing the number of facility devices 20 to be controlled than adjusting the control amount of each facility device 20.

(5-7) Modification 1G
The control device 30 according to the present embodiment may be connected to the equipment device 20 via the network NW. In addition, a schedule creation device 40 that creates a schedule related to permission for DR control may be provided separately from the control device 30. For example, as shown in FIG. 15, each device may be configured in a cloud type via the Internet or the like. With such a configuration, it is possible to distribute the processing load required for creating a schedule.
