Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

It should be noted that although functional block division is performed in a device diagram and a logic sequence is shown in a flowchart, in some cases, the steps shown or described may be performed in a different order than the block division in the device, or in the flowchart. The terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the present application.

Regional energy supply systems refer to a centralized energy supply system established to meet energy demand within a particular region, each system supplying energy to a plurality of regional grids and delivering energy from a fixed supply station to individual users through the regional grids to complete the supply of energy. Typically, a regional network includes a plurality of energy supply points, that is, a regional network includes a plurality of users, and a network can supply energy to a plurality of end users, and the temperature of the energy supplied to the user side is defined as a fixed value. The regional energy supply system can adopt various energy forms, such as fuel gas, electric power, cold energy, heat energy and the like, and can be flexibly combined and regulated according to actual needs.

In the related art, the end points of two adjacent regional pipe networks are generally communicated with each other and are provided with valves, however, the valves are opened only when one of the regional pipe networks fails, and the regional energy supply stations which do not fail provide energy to the energy supply points of the failed region. When the regional pipe network normally operates, the valve is in a closed state, each regional energy supply station provides energy for an energy supply point in a fixed range, and the dynamic regulation and control of the whole regional energy supply system cannot be realized through the valve, so that when the energy demand of the energy supply point is overlarge or is overlarge, the hydraulic balance of the pipe network is difficult to maintain, the condition of insufficient single-regional energy supply or excessive energy storage possibly is caused, and the economical efficiency of the pipe network operation is not facilitated. Especially for regional energy supply systems, the daily electricity costs are enormous, and therefore, a reasonable strategy needs to be formulated to divide the energy supply region.

Based on this, the embodiment of the application provides a multi-area energy supply method, a system, a device, electronic equipment and a medium, which can count the consumption of energy before a certain period, dynamically regulate and control the energy transportation between the subsequent area energy supply stations, improve the utilization rate of energy between areas and ensure the economic benefit of the area energy supply stations.

It is understood that the multi-zone energy supply in the embodiments of the present application may refer to providing heat energy, or providing cold energy or other energy that may be intensively supplied by a zone, and cold energy is used for description when embodiments are described in the present application.

The method, system, device, electronic equipment and medium for supplying multi-area energy stations provided in the embodiments of the present application are specifically described through the following embodiments, and the multi-area energy station supply system in the embodiments of the present application is described first.

Referring to fig. 1, in some embodiments, a system 100 includes:

at least two regional energy supply stations 110;

a plurality of energy supply points 120; wherein, the plurality of energy supply points 120 are all supplied with energy by the regional energy supply station 110;

a main line 130 connected to the regional energy supply station 110;

a plurality of branch pipelines 140 for connecting the main pipeline 130 and the corresponding energy supply points 120;

the dynamic switch valve 150, the dynamic switch valve 150 is located on the main pipeline 130, and is arranged at two sides of the intersection point of each branch pipeline 140 and the main pipeline 130;

and a controller 160 for controlling the switching state of the dynamic switching valve 150 to control the energy paths of the respective regional energy supply stations 110 and the corresponding energy receiving points 120, thereby dividing the energy supply range of the regional energy supply stations 110.

In some embodiments, the regional energy supply station can provide centralized supply and management of multiple energy sources, such as electricity, heat, cold, etc., to surrounding buildings or regions to improve energy utilization efficiency and reduce energy consumption costs. In some embodiments, the energy supply points are a plurality of user points, and the regional energy supply stations supply energy to the energy supply points.

In some embodiments, the main conduit is the primary conduit connecting the regional energy supply station and the plurality of regions for delivering a substantial amount of energy to the connected regions to effect the supply of energy. It will be appreciated that branch lines are branches and extensions of the main line, connecting to specific energy supply points, i.e. to specific users, and providing the energy supply points with the appropriate amount of energy. It will be appreciated that, because the design and operation management of the main and branch pipelines directly affect the stability and reliability of the energy supply, generally in a multi-zone energy station supply system, a dendritic pipe network or a ring pipe network is used to implement the transportation of energy.

In some embodiments, the dynamic switch valve is located on the main pipeline and is disposed on two sides of the intersection point of each branch pipeline and the main pipeline, and in some embodiments, the dynamic switch valve receives an instruction opening or closing instruction sent by the controller to perform opening or closing operation.

In some embodiments, the controller may be a neural center and a command center of the system, and may generate operation control signals according to the instruction operation codes and the time sequence signals to complete instruction fetching and instruction execution control. For example, the controller can send an instruction of opening or closing to the dynamic switch valve, so as to control the opening and closing states of the dynamic switch valve, so as to control the energy paths of the energy supply stations in each area and the corresponding energy supply points, and divide the energy supply range of the energy supply stations in each area. In some embodiments, the controller is further capable of controlling the number and frequency of operation of the supplies of the regional energy supply station.

In some embodiments, the main conduit of the multi-zone energy station supply system includes a power supply main conduit and a power return main conduit; the energy supply main pipeline is connected with the energy supply point through an energy supply branch pipeline, and the energy return main pipeline is connected with the energy supply point through an energy return branch pipeline;

the controller is specifically for:

dynamic switch valves are arranged on two sides of the intersection point of the energy supply main pipeline and each energy supply branch pipeline on the energy supply main pipeline;

dynamic switch valves with the same quantity as the energy supply main pipelines are arranged on two sides of the intersection point of the energy return main pipeline and each energy return branch pipeline on the energy return main pipeline, so that each regional energy supply station can provide energy for any energy supply point in the system through the adjustment of the dynamic switch valves;

If the system pipe network is a dendritic pipe network, the total number of dynamic switch valves on the energy supply pipe of each system is m+1, and the total number of dynamic switch valves on the energy return pipe of the system is m+1; if the system pipe network is an annular pipe network, the total number of dynamic switch valves on energy supply pipes of each system is m+3, and the total number of dynamic switch valves on energy return pipes in each system is m+3; m is the number of energy supplied points, and m is a positive integer greater than or equal to 1. It can be understood that m represents the number of energy supply points (users), but if a plurality of energy supply points form a unit, the regional energy supply stations set dynamic switch valves in units of units, that is, when the system pipe network is a dendritic pipe network, the number of the dynamic switch valves should be less than m+1; when the system pipe network is an annular pipe network, the number of the dynamic switch valves is less than m+3.

It will be appreciated that in order to ensure the supply and recovery of energy, the main conduit and each branch conduit need to have a corresponding number of supply and return conduits in order to effect the supply and recovery of energy. The energy supply dry pipeline is used for conveying energy to all energy supply points, the energy return dry pipeline is used for recycling waste energy generated by all energy supply points, and the waste energy is conveyed back to the energy supply station for recycling after being treated.

Referring to fig. 2, fig. 2 is a schematic diagram of the connection of the power supply dry line, the power return dry line and the dynamic switching valve.

In some embodiments, S1 represents the energy supplied point, i.e., the user, valves S1-SL represent the supply mains to the left of the energy supplied point, valves S1-SR represent the supply mains to the right of the energy supplied point, valves S1-RL represent the return mains to the left of the energy supplied point, and valves S1-RR represent the return mains to the right of the energy supplied point. It can be understood that in the state 1 and the state 2, the 4 dynamic switch valves of the energy supply dry pipeline and the energy return dry pipeline are normally opened, and the energy source normally flows in the energy supply area where the user is located.

It will be appreciated that in state 3, assuming that the left side of S1 is cold station A and the left side of S2 is cold station B, then valves S1-SL and S1-RL are open and valves S1-SR and S1-RR are closed, energy is supplied to S1 by cold station A through valves S1-SL and then energy is recovered through valves S1-RL. Specifically, the flow direction of the energy source is the valve S1-SL→S1→the valve S1-RL.

It will be appreciated that in state 3, assuming that the left side of S1 is cold station A and the left side of S2 is cold station B, then valves S1-SR and S1-RR are open and valves S1-SL and S1-RL are closed, energy is supplied to S1 by cold station B through valves S1-SR and then energy is recovered through valves S1-RR. Specifically, the flow direction of the energy source is the valve S1-SR→S1→the valve S1-RR.

It is understood that the same number of dynamic switch valves are arranged on the energy supply main pipeline and the energy return main pipeline at the same time, so that energy can flow in from different directions of the energy supply main pipeline, and the energy supply range of each regional energy supply station is selected and optimized.

Referring to fig. 3-a, 3-b, 4-a and 4-b, fig. 3-a, 3-b, 4-a and 4-b are schematic diagrams of energy supply dry pipelines or energy return dry pipelines, the connection mode of the energy supply dry pipelines is not limited to this, and the pipe network area setting mode of adjusting and controlling the energy supply range through dynamic switch valves is within the protection scope of the application. In some embodiments, V1-V13 in the figures represent dynamic switching valves, S1-S10 represent energy supply points, namely, the users S1-S10, and the cold station a and the cold station B represent two regional energy supply stations, it being understood that the regional energy supply stations are not limited to cold stations, but may be stations for supplying other energy sources, such as thermal energy stations.

In fig. 3-a, when the dynamic switching valve V3 is closed, the cold station a supplies cold to S1 and S2, and the cold station B supplies cold to S3 and S4.

In fig. 3-B, when the valves V4 and V8 are closed, the cold station a supplies cold to the users S1, S2, S3, S7, S8, S9, S10 and the cold station B supplies cold to the users S4, S5, S6.

In fig. 4-a, when valve V2 is closed, cold station a supplies cold to S1, cold station B supplies cold to S2, S3 and S4;

in fig. 4-B, when the valves V3, V9 and V12 are closed, the cold station a supplies cold to S1, S2, S8, S9 and the cold station B supplies cold to S3, S4, S5, S6, S7, S10.

It can be appreciated that by controlling the dynamic on-off valves of the regional internal network, a fine division of the cooling range of each regional energy supply station can be achieved. And the regional energy supply station can accurately match and schedule the supply and demand of the system according to the energy consumption of each energy supplied point and the energy supply capacity. It will be appreciated that the operation of the multi-zone power supply is actually based on individual zone power supply stations each supplying power to a divided zone, and that hydraulic imbalance or supply stability problems after communication of the plurality of zone power supply stations do not occur, simplifying operation and control of the system. Meanwhile, the energy consumption of each energy supplied point in the previous day can be counted at regular time, so that the energy consumption and the supply areas of the energy supply stations in each area can be divided, and the pipeline network can be optimally scheduled according to the most energy-saving or most economical mode.

It can be understood thatThe method is characterized in that the electricity price is high in the peak period, and the ice melting refrigeration is more energy-saving than the refrigeration in the peak period, so that the formulated target division strategy should preferably meet the ice melting refrigeration in the peak period of the electricity price, and secondly preferably meet the ice melting refrigeration in the flat period, and the part with insufficient ice melting and refrigeration in the ordinary period adopts ice melting and refrigerant combined refrigeration. It can be understood that the normal period ice melting refrigerating capacity is the residual ice melting capacity used in the electricity consumption peak period.

It can be understood that the ice melting refrigeration is adopted in the peak period of electricity price, the ice melting refrigeration is adopted in the ordinary period, and the refrigerator is adopted for the part with insufficient ice melting, so that the electricity fee can be saved to the greatest extent. It can be understood that, according to the position of the energy supply point in the pipe network, in the target division strategy, the energy storage sum of the first area corresponding to the divided first area should be larger than the energy supply amount of the peak period of the first area energy supply station, and the energy storage sum of the second area corresponding to the divided second area should be larger than the energy supply amount of the peak period of the second area energy supply station, namely ，/>Thereby ensuring that the peak time of the first area and the second area can adopt full ice melting for cooling.

In some embodiments, the energy division parameters are calculated by an energy calculation model, thereby obtaining a total energy supply amount, a total time-by-time energy consumption amount, and a sum of remaining energy storage amount and energy production amount in the peak period. In some embodiments, if the sum of the energy stores is ) Is greater than or equal to the total energy supply amount in the peak period (+)>) And is smaller than the total energy supply (+)>) And during peak timeSum of the remaining energy and the production energy (+)>) Less than total time-by-time energy consumption (+)>) I.e. +.>，/>The method is characterized in that the total cooling requirement of each hour of the flat period cannot be met due to the fact that the residual ice melting amount in the ordinary period and the refrigerating capacity of the refrigerating machine cannot meet the total cooling requirement of each hour of the flat period, the cooling quality of a user is reduced due to the fact that the total cooling requirement of each hour of the flat period cannot be met, the ice melting amount in the peak period needs to be reduced, the ice melting amount in part of the peak period is transferred to the ordinary period for cooling, and meanwhile, in order to ensure the cooling quality in the peak period, the refrigerating machine needs to be started in the peak period, and the refrigerating machine and the ice melting combined cooling is adopted. It can be understood that under the condition of meeting the cooling requirements of other periods, ice melting and cooling are adopted as much as possible in the peak period, and at this time, the cost calculation model can be used for calculating the division plan cost of each functional range. It can be understood that the cost calculation model can calculate the total cost of the system operation by using the cooling capacity according to the electric charge of each period, the dividing range of the energy supply points. In some embodiments, the minimum operating cost of cold station A is +. >The minimum operating cost of cold station B is +.>The total running cost of the system is +.>，Indicating the choice of minimum total operating costs, i.e. +.>，/>. In some embodiments, the policies of the cold stations a and B may be optimized continuously to obtain the lowest running cost of each cold station, selecting the dividing range with the smallest overall price to divide the optimal cooling range, and adjusting the on-off state of each dynamic switch valve according to the optimal cooling range.

Referring to fig. 16-a and 16-b, an operation scenario diagram after the optimal range division is performed. In fig. 16-a and 16-b, since the flat period uses only the refrigerator for cooling and cannot meet the cooling requirement of the energy supply point (user), the ice melting and refrigerating machine is used for cooling in the flat period, and since part of the ice storage amount in the peak period is transferred to the flat period for cooling, the ice melting and refrigerating machine is also used for cooling in the peak period for combined cooling.

17-a and 17-b, on the basis of the above-mentioned peak period and average period adopting the ice melting and refrigerating machine refrigeration scenario, as the cooling demand of the flat period increases, the ice melting amount of the flat period also increases, so that the ice melting amount of the peak period gradually decreases, the number of the refrigerating machines which are started and the load rate of the refrigerating machines gradually increase until all the refrigerating machines in the system reach full-load operation, and the maximum cooling capacity of the cold station, namely the designed cooling capacity of the cold station, is achieved. At this time, the calculation is still carried out according to the maximum cost of the cost calculation model, the range corresponding to the minimum operation cost is obtained, and the opening or closing of the dynamic switch valve is controlled according to the range.

In some embodiments, a pipe network calculation model corresponding to the regional energy supply station can be obtained by measuring the energy flow of each energy supplied point in the energy supply range of each regional energy supply station, then the working lift range of the supply device in the regional energy supply station is obtained by the pipe network calculation model corresponding to the regional energy supply station, and further the supply type selection parameters are obtained according to a preset characteristic curve set and the working lift range of the supply device.

In some embodiments, a plurality of pipe network operation conditions under each regional energy supply station may be obtained, where each pipe network operation condition is used to represent a load factor combination relationship of a plurality of users, and the operation conditions of any two pipe networks are different.

It will be appreciated that the zone total load rate model is determined by the time-by-time energy consumption of each energy supplied point within the zone.

In some embodiments, the predetermined set of feeder characteristics is determined by feeder factory parameters, each model of feeder having a respective characteristic. That is, each energy supply device controlled by the regional energy supply station has a respective characteristic curve.

In some embodiments, the operating parameters include the number of supplies and the operating frequency. The method can predict the working parameters of the regional energy supply station according to the time-by-time energy consumption and the supply type selection parameters of each energy supply point, and calibrate the number and the operating frequency of the supply devices of the regional energy supply station according to the predicted working parameters, so that the control of regional energy can be effectively simplified.
