The embodiment of the application provides an energy regulation and control method of a flexible-straight interconnection system, which is executed by a flexible-straight interconnection measurement and control terminal, wherein the flexible-straight interconnection measurement and control terminal can be a server or terminal equipment, and the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server for providing cloud computing service. The terminal device may be a smart phone, a tablet computer, a notebook computer, a desktop computer, or the like, but is not limited thereto, and the terminal device and the server may be directly or indirectly connected through a wired or wireless communication manner, as shown in fig. 1, the method includes steps S101, S102, S103, S104, and S105, where:

step S101: and acquiring operation data of each platform region in the flexible and straight interconnection system, and performing platform region operation monitoring based on the operation data of each platform region to obtain a platform region load rate corresponding to each platform region.

For the embodiment of the application, the flexible direct current interconnection system connects a plurality of adjacent areas by using a flexible direct current technology interconnection method to form a micro-grid, and each area in the micro-grid can be subjected to energy sharing, so that self-management, self-balancing and self-adjustment of the micro-grid can be realized to a certain extent, and the energy utilization efficiency is improved, wherein the flexible direct current interconnection system not only comprises a plurality of adjacent areas, but also comprises equipment in each area, and of course, the flexible direct current interconnection system also comprises photovoltaic equipment, energy storage equipment and the like. The operation data of the platform area is data representing the operation condition of the platform area, and at least comprises the following steps: current, voltage, power, frequency, ramp, power factor, etc., although other data may be included, embodiments of the present application are not limited. Furthermore, the operation of the areas is monitored based on the operation data of each area to obtain an area load rate corresponding to each area, wherein the area load rate is used for representing the load condition of the areas, the operation of the area equipment is affected by the higher area load rate, and the full utilization of energy in the areas is affected by the lower area load rate.

Step S102: and determining an abnormal load platform area from all the platform areas based on the platform area load rate and the abnormal load threshold value corresponding to each platform area.

For the embodiment of the application, based on the platform area load rate and the abnormal load threshold value corresponding to each platform area, at least one abnormal load platform area is determined from all the platform areas, and specifically, when the load rate of the platform area is greater than the abnormal load threshold value, the platform area is determined to be the abnormal load platform area; and when the load rate of the platform area is not greater than the abnormal load threshold value, determining to be a normal load platform area, namely selecting an abnormal load platform area needing to reduce the load rate from all the platform areas. The abnormal load threshold is determined by the related technicians based on a large number of experimental operations, and of course, the user can also set the abnormal load threshold by himself according to actual conditions, and the abnormal load threshold is preferably selected to be 50%.

Step S103: determining an energy regulation type corresponding to the abnormal load platform region based on the platform region load rate and the regulation load threshold corresponding to the abnormal load platform region, wherein the energy regulation type comprises: photovoltaic energy storage equipment regulation and control and inter-platform transfer.

For the embodiments of the present application, the energy modulation types include: the photovoltaic energy storage equipment regulation and control and inter-station transfer supply are based on reverse power supply of the photovoltaic equipment and the energy storage equipment in the flexible-direct interconnection system to the abnormal load station so as to reduce the load rate of the abnormal load station; the inter-station transfer is to transfer energy to an abnormal load station area through a station area with lower station area load rate in the flexible-direct interconnection system so as to realize load balancing among stations. However, different energy regulation and control types have respective characteristics, and are simpler to operate compared with the inter-platform transfer supply for regulating and controlling the photovoltaic energy storage equipment, but the photovoltaic equipment and the energy storage equipment store limited electric energy, so that the method is more suitable for the condition of small abnormal degree of the load rate of the platform; for inter-station transfer, transfer operation is complex, and transfer control is difficult, that is, power transfer is performed to an abnormal load station by using a normal load station, which may cause an increase in load rate of the normal load station, and thus, the abnormal load station is formed. Therefore, a regulation and control load threshold is set in the embodiment of the application, and when the platform load rate of the abnormal load platform is not higher than the regulation and control load threshold, the energy regulation and control type is determined to be photovoltaic energy storage equipment regulation and control; and when the load rate of the abnormal load station area is higher than the regulation load threshold, determining that the energy regulation type is inter-station transfer. The regulation load threshold is determined by a related technician based on a large amount of experimental verification, and a user can also set the regulation load threshold according to actual requirements, preferably, the regulation load threshold is selected to be 70%.

Step S104: when the energy regulation type is inter-station transfer, transfer analysis is performed based on the station load rate corresponding to each normal load station, a transfer station is determined from all the normal load stations, and transfer information corresponding to the transfer station is determined.

For the embodiment of the application, when the energy regulation type is inter-station transfer, the overload condition of the abnormal load station is serious, and the energy regulation type is determined as the inter-station transfer because the photovoltaic equipment and the energy storage equipment in the flexible-direct interconnection system have weaker reverse power supply regulation and control capability. Furthermore, transfer analysis is performed based on the load rate of the areas corresponding to each normal load area, transfer information corresponding to the transfer areas and transfer information corresponding to the transfer areas are determined, various transfer analysis modes exist, and different types of transfer analysis can be adopted for different numbers of abnormal load areas. When the energy regulation type is photovoltaic energy storage equipment regulation, the photovoltaic equipment and/or the energy storage equipment in the flexible-straight interconnection system are/is controlled to supply power reversely to the abnormal load platform area, so that the energy regulation of the flexible-straight interconnection system is completed, and the load balance between adjacent platform areas is realized.

In one case, when the number of abnormal load areas is one, selecting a normal load area with the lowest area load rate as a transfer area, and performing transfer analysis based on operation data of the transfer area to determine transfer information, wherein the transfer information includes but is not limited to: converting voltage and converting power. However, it may not be possible to meet the needs of the abnormal load areas by using only the normal load area with the lowest area load ratio as the transfer area, and preferably, the transfer analysis is performed based on the area load ratio corresponding to each normal load area and the area load ratio corresponding to the abnormal load area according to the principle of minimum transfer area number, where the principle of minimum transfer area number is used to minimize the number of transfer areas, and reduce the complexity of transfer operation as much as possible. In another case, when the number of the abnormal load areas is multiple, transfer analysis of a single area can be performed based on each abnormal load area to obtain transfer areas and transfer information corresponding to each abnormal load area, and the transfer areas and transfer information of each abnormal load area are synthesized to determine the transfer areas and transfer information corresponding to the flexible and straight interconnection system. However, when the number of the abnormal load areas is large, the transfer analysis is performed on each abnormal load area, so that not only is a high requirement on the analysis capability of the flexible-direct interconnection measurement and control terminal provided, but also the transfer area and transfer information of each abnormal load area are difficult to integrate. Preferably, when the number of the abnormal load areas is multiple, comprehensive analysis is performed firstly based on the area load rate corresponding to each abnormal load area to obtain comprehensive abnormal load characteristics corresponding to the flexible-direct interconnection system, then transfer analysis is performed based on the area load rate corresponding to each normal load area and the comprehensive abnormal load characteristics, transfer areas are determined from all normal load areas, transfer information corresponding to the transfer areas is determined, and it is easy to know that the transfer areas and the transfer information determined herein are for the whole flexible-direct interconnection system.

Step S105: and sending the transfer information to a corresponding transfer area control end so as to complete energy regulation and control of the flexible-direct interconnection system, wherein the transfer area control end is used for executing energy transfer operation.

For the embodiment of the application, each transfer station area corresponds to a transfer station area control end, and the transfer station area control end is used for controlling the transfer station area to perform energy transfer operation, specifically, after transfer information is sent to the transfer station area control end, the transfer station area control end controls the transfer station area to perform energy transfer to the abnormal load station area according to the transfer information.

Therefore, in the embodiment of the application, the platform region load rate of each platform region is obtained by monitoring the operation data of each platform region in the flexible and straight interconnection system in real time, the energy regulation type is determined based on the platform region load rate and the regulation load threshold corresponding to the abnormal load platform region, and the complexity of operation can be reduced to a certain extent by adopting different energy regulation types according to different load conditions of the abnormal load platform region. And when the energy regulation type is inter-station transfer, transfer analysis is performed based on the station load rate corresponding to each normal load station, transfer information corresponding to the transfer station and the transfer station is determined, and the transfer information is sent to a corresponding transfer station control end so as to complete energy regulation of the flexible and straight interconnection system. The transfer supply area and transfer supply information determined through transfer supply analysis can enable energy regulation and control of the flexible and straight interconnection system to be more consistent with actual conditions of the area, and further, the electric energy quality of the flexible and straight interconnection system is improved.

Further, in order to make the flexible-direct interconnection system easy to operate and higher in stability when energy sharing is performed, in the embodiment of the present application, determining an energy regulation type corresponding to an abnormal load zone based on a zone load rate and an energy regulation policy corresponding to the abnormal load zone includes:

comparing the sizes of the platform region load rates and the regulation load threshold values corresponding to the abnormal load platform region;

when the load rate of the platform region is not greater than the regulation load threshold, determining that the energy regulation type corresponding to the abnormal load platform region is photovoltaic energy storage equipment regulation, wherein the photovoltaic energy storage equipment regulation is to realize load balancing among the platform regions through photovoltaic and/or energy storage equipment.

For the embodiments of the present application, the energy modulation types include: the photovoltaic energy storage equipment regulation and control and inter-station transfer have the characteristics corresponding to different energy regulation types, so that the embodiment of the application adopts different energy regulation types for abnormal load stations with different station load rates, and the flexible and straight interconnection system is simple to operate when energy sharing is carried out, and has higher stability.

For regulation and control of the photovoltaic energy storage equipment, the operation is simpler than the transfer between the stations, but the photovoltaic equipment and the energy storage equipment are limited in stored electric energy, so that the method is more suitable for the condition of small abnormal degree of the load rate of the stations; for inter-station transfer, transfer operation is complex, and transfer control is difficult, that is, power transfer is performed to an abnormal load station by using a normal load station, which may cause an increase in load rate of the normal load station, and thus, the abnormal load station is formed. Therefore, a regulation and control load threshold is set in the embodiment of the application, and when the platform load rate of the abnormal load platform is not higher than the regulation and control load threshold, the energy regulation and control type is determined to be photovoltaic energy storage equipment regulation and control; and when the load rate of the abnormal load station area is higher than the regulation load threshold, determining that the energy regulation type is inter-station transfer. Through the mode, when the photovoltaic energy storage equipment is regulated and controlled to finish inter-platform load balancing, the mode of regulating and controlling the photovoltaic energy storage equipment is preferably selected, the operation difficulty is reduced in regulation and control operation, and inter-platform transfer is selected for an abnormal load platform with high platform load rate, so that the power supply stability of the flexible and straight interconnection system is ensured to a certain extent. The regulation load threshold is determined by a related technician based on a large amount of experimental verification, and a user can also set the regulation load threshold according to actual requirements, preferably, the regulation load threshold is selected to be 70%.

Therefore, in the embodiment of the application, different energy regulation and control types are adopted for abnormal load areas with different area load rates, so that the flexible and straight interconnection system is simple to operate and higher in stability when energy sharing is performed.

Further, in order to reduce complexity of transfer operation, in an embodiment of the present application, as shown in fig. 2a and 2b, transfer analysis is performed based on a load factor of a zone corresponding to each normal load zone, a transfer zone is determined from all normal load zones, and transfer information corresponding to the transfer zone is determined, including: step S1041-step S1043, wherein:

step S1041: when only one abnormal load station area exists, according to the principle of minimum transfer station area quantity, transfer analysis is carried out based on the station area load rate corresponding to each normal load station area and the station area load rate corresponding to the abnormal load station area, a transfer station area is determined from all the normal load station areas, transfer information corresponding to the transfer station area is determined, wherein the transfer information comprises: power and voltage are transferred.

For the embodiment of the application, the principle of the least number of transfer areas is used for minimizing the number of transfer areas and reducing the complexity of transfer operation as much as possible, so that transfer analysis is performed based on the area load rate corresponding to each normal load area and the area load rate corresponding to the abnormal load area, and transfer information corresponding to at least one transfer area and each transfer area is determined. For the specific rule of the principle of minimum number of transfer areas, the embodiment of the application is not limited any more, as long as the minimum number of transfer areas can be achieved. Preferably, the normal load area sequences with the area load rates from low to high are obtained based on the inverse sequence arrangement of the area load rates corresponding to all the normal load areas, then the normal load areas are selected one by one from the normal load area sequences, the shared electric energy is calculated based on the area load rates, the area rated capacity and the abnormal load threshold values of the normal load areas, the shared electric energy of the normal load areas is determined, and meanwhile, the electric energy demand is calculated based on the area load rates, the area rated capacity and the abnormal load threshold values of the abnormal load areas, and the electric energy demand of the abnormal load areas is determined. Further, whether the sharing demand of a normal load area is greater than the demand energy is determined, and when the sharing demand is greater than the demand energy, the normal load area is determined to be a transfer area, and transfer information is determined according to operation data of the transfer area, wherein the transfer information includes but is not limited to: the power supply voltage and power supply power are converted, and reasonable power supply information can guarantee the stability of power supply of the flexible-direct interconnection system to a certain extent. When the total shared electric energy of the two normal load areas is larger than the required electric energy, determining the two normal load areas as transfer areas and determining transfer information; and when the power consumption is not greater than the required power consumption, continuously selecting the next normal load platform area until the revolution platform area can meet the requirement of the abnormal load platform area.
