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.

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;

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.

In some embodiments, the first regional energy supply station may be a cold station a and the second regional energy supply station may be a cold station B, the cold station a configuring the chiller capacityTen thousands kW cold accumulation capacity of cold station A>Ten thousand kWh; cold station B is provided with the installed capacity of the refrigerator>Ten thousands kW cold accumulation capacity of cold station B +.>Ten thousand kWh. In some embodiments, the sum of the stored energy is the sum of the cold storage capacities of cold station a and cold station B.
It is understood that the cold storage is used to provide ice melting refrigeration to the system and the installed capacity is the refrigerator refrigeration. It can be understood that the refrigerating machine is used for refrigerating by mechanically compressing and expanding working medium to absorb and release heat so as to reduce the temperature, and the ice-melting refrigerating is used for absorbing heat by utilizing the phase change (melting) of substances so as to achieve the effect of reducing the temperature. Because ice-melting refrigeration only needs to provide enough heat to melt ice, and does not need to consume a large amount of electricity to drive the mechanical compression and expansion working medium like refrigerating by a refrigerator, the energy consumed by ice-melting refrigeration is less than that consumed by refrigerating by the refrigerator, and a large amount of electricity is saved compared with that consumed by refrigerating by the refrigerator. In addition, ice melting and refrigeration can also utilize heat in the environment to accelerate ice melting, so that less energy is consumed. It will be appreciated that energy storage (ice storage) is typically performed at night, as the system is not only less energy consuming at night, but also has a lower electricity price than at daytime.
In some embodiments, the total energy consumption and the stored energy sum may be compared to determine a supply scenario. Specifically, if the total energy consumption is smaller than the energy storage sum, the energy storage sum is enough to provide energy for the whole system, a refrigerator is not needed to be used for refrigeration, and the system meets the whole-day ice melting and cooling conditions. It can be understood that since cold accumulation is performed when the electricity price is lowest at night and ice melting and cooling are adopted in the daytime, the most economical cooling operation in the whole day can be ensured by adopting full ice melting and cooling. In some embodiments, cold storage may be performed at low electricity rates, such as 1-7 hours, and 24-0 hours.

10-a and 10-b, in some embodiments, if the total energy consumption is less than or equal to the first zone energy storage sum, i.eThe entire system can be supplied with energy by the cold station a alone. It will be appreciated that the entire system may also be powered by a combination of cold stations a and B, as embodiments of the present application are not particularly limited.
Referring to FIGS. 11-a and 11-b, in some embodiments, if the total energy consumption is less than or equal to the second zone energy storage sum, i.eThe entire system can be supplied with energy by the cold station B alone.

Step S503, if the energy storage sum is greater than or equal to the total energy supply amount and less than the total energy supply amount in the peak period, and the sum of the remaining energy storage amount and the energy production amount in the peak period is greater than the total time-by-time energy consumption amount, setting the energy storage sum in the first area to be greater than or equal to the energy supply amount in the peak period of the first area energy supply station, and setting the energy storage sum in the second area to be greater than or equal to the energy supply amount in the peak period of the second area energy supply station; energy is provided by adopting energy storage in peak time, and energy is provided by adopting residual energy storage and energy production in ordinary time; wherein the energy is generated by an energy generator; the energy storage sum comprises a first area energy storage sum and a second area energy storage sum, the residual energy storage amount is obtained by subtracting the total energy supply amount of the peak period from the energy storage sum, and it is understood that when the total energy supply amount of the peak period is exactly equal to the total energy storage sum, the residual energy storage amount in the normal period is 0, that is, the residual energy storage amount is 0, and at the moment, the energy production mechanism energy is adopted in the normal period.
In some embodiments, the energy dividing parameters may be obtained through an energy calculation model, and the sum of the total energy supply amount, the total time-by-time energy consumption amount, and the remaining energy storage amount and the energy production amount in the peak period may be known. In some embodiments, the peak total energy supply may be [ ] ) Sum of energy storage ()>) And total energy supply quantity (+)>) Comparing the total time-by-time energy consumption (++>) The sum of the residual energy storage and the energy production in peak time) A comparison is made to determine the specific supply scenario.

It can be understood that, because the electricity price is high in the peak period, and the ice melting refrigeration is more energy-saving than the refrigeration, the formulated target division strategy should preferably satisfy the ice melting refrigeration in the peak period of the electricity price, and then preferably satisfy 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.
Referring to fig. 13-a and 13-B, fig. 13-a and 13-B are schematic diagrams of cooling station a and cooling station B in the system using ice-melting refrigeration during peak hours and using ice-melting and ice-making machine during normal times.
Referring to fig. 14-a and 14-B, fig. 14-a and 14-B are schematic diagrams of the system in which the cold stations a and B use ice-melting refrigeration during peak periods and use ice-making machines for refrigeration during normal periods, and the peak periods just consume the ice-storage amount, so that the ice-making machines are used for refrigeration during normal periods. It is understood that when dividing each energy supply area, the amount of melted ice should be ensured to be consumed, so that a cost calculation model may be used to calculate the operation cost of the multiple division schemes, and a target division strategy corresponding to the operation cost with the lowest price may be used.
Referring to fig. 15, in some embodiments, step S103 further includes, but is not limited to, steps S601 to S603:
step S601, obtaining the total energy supply quantity and the total energy supply quantity in the peak period, and comparing the total energy supply quantity and the total energy supply quantity in the peak period;
Step S602, obtaining total time-by-time energy consumption and the sum of the residual energy storage capacity and the energy production capacity in the peak time, and comparing the total time-by-time energy consumption with the sum of the residual energy storage capacity and the energy production capacity in the peak time;
step S603, if the energy storage sum is greater than or equal to the total energy supply amount and less than the total energy supply amount in the peak period, and the sum of the remaining energy storage amount and the energy production amount in the peak period is less than the total time-by-time energy consumption amount, energy storage and energy production are adopted to provide energy in the peak period and the average period;

the total energy supply amount is greater than or equal to the total energy consumption amount;
the overall price is minimal; the total price refers to the sum of peak time electricity prices and ordinary time electricity prices.
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 the sum of the remaining energy and the energy production in the peak period (+)>) 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.

In some embodiments, the minimum operating cost of cold station A is +. >Minimum operation of cold station BThe cost 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.
