Abstract
Description
Technical Field
[0001] The present application relates to the field of energy storage technology, and in particular to an energy storage device control method, apparatus, computer equipment, storage medium, and computer program product. Background Art
[0002] In the process of electricity use, the power resources consumed in different periods of electricity consumption are different. For example, during the peak period of concentrated electricity consumption, the supply and demand of electricity is tight. In order to ensure the normal supply of electricity, the power supply cost required in the power generation link and the transmission and distribution environment is relatively high. On the contrary, during the low period of electricity consumption, the supply and demand of electricity is loose, and the power supply cost will be relatively lower. Therefore, in order to reasonably consider the time value of electricity, the electricity price mechanism used in my country is the time-of-use electricity price mechanism, that is, different electricity price levels are set for each time period of the day, so that the time-of-use electricity price level is closer to the power supply cost of the power system.
[0003] How to profit from energy storage based on the current time-of-use electricity pricing mechanism is a key concern for industrial and commercial energy storage applications on the user side. Current energy storage companies typically control the charging of energy storage devices during low electricity price periods and the discharge of energy storage devices to the grid during peak electricity price periods to maximize energy storage returns. However, current control strategies focus solely on price fluctuations during low and peak periods, resulting in limited profit margins and low profit margins, and are unable to significantly increase the energy storage benefits brought by energy storage applications. Summary of the Invention
[0004] Based on this, it is necessary to provide a method, device, computer equipment, computer-readable storage medium and computer program product for controlling energy storage equipment that can improve energy storage benefits in response to the above technical problems.
[0005] In a first aspect, the present application provides a method for controlling an energy storage device, the method comprising:
[0006] In the case where there are a first energy storage area and a second energy storage area that meet the regional energy storage cooperation conditions, respectively determining the resource exchange direction of the first energy storage area and the second energy storage area; the absolute value of the electricity price difference between the first energy storage area and the second energy storage area is greater than or equal to a preset difference threshold;
[0007] According to the resource exchange direction of the first energy storage area and the second energy storage area, the first target energy storage device in the first energy storage area and the second target energy storage device in the second energy storage area are respectively controlled to exchange resources with the regional power grid in the current regional coordination cycle; the resource exchange direction of the first energy storage area is opposite to the resource exchange direction of the second energy storage area.
[0008] In the above embodiment, by having two energy storage areas with an absolute value of a price difference greater than or equal to a preset difference threshold exchange resources with the regional power grid in opposite directions, the control strategy can be expanded from focusing solely on the low and high electricity prices in a single area to focusing on the price differences between different areas. As long as the price difference between the areas exceeds the preset difference threshold, resource exchange can be profitable, effectively expanding the profit space for resource exchange between energy storage applications and the regional power grid, improving the profit rate of resource exchange, and thus significantly improving the energy storage benefits brought by energy storage applications.
[0009] In some embodiments, the method further comprises:
[0010] Obtaining grid information data of each energy storage area included in the energy storage area set, as well as the area number of each energy storage area;
[0011] Based on the number of the energy storage areas and the grid information data, it is determined whether there is a first energy storage area and a second energy storage area that meet the area cooperative energy storage conditions.
[0012] In the above embodiment, the corresponding regional coordinated energy storage conditions are determined by the number of areas in each energy storage area, and then the presence of a first energy storage area and a second energy storage area that meet the regional coordinated energy storage conditions is determined based on the grid information data. This allows accurate selection of the first energy storage area and the second energy storage area that are more suitable for regional coordinated energy storage based on the actual number of areas.
[0013] In some embodiments, determining whether there are a first energy storage area and a second energy storage area that meet the regional energy storage cooperation conditions based on the number of the energy storage areas and the grid information data includes:
[0014] When there are two energy storage areas, determining a price difference between the two energy storage areas according to the grid information data;
[0015] When the absolute value of the electricity price difference is greater than or equal to a preset difference threshold, two energy storage areas in the energy storage area set are determined as a first energy storage area and a second energy storage area that meet the regional coordinated energy storage conditions.
[0016] In the above embodiment, when the energy storage management platform manages two energy storage areas, it is only necessary to compare the absolute value of the electricity price difference between the two energy storage areas with a preset difference threshold to quickly determine whether the energy storage areas managed by the energy storage management platform meet the regional energy storage matching conditions, further improving the speed and accuracy of determining the first energy storage area and the second energy storage area.
[0017] In some embodiments, determining whether there are a first energy storage area and a second energy storage area that meet the regional energy storage cooperation conditions based on the number of the energy storage areas and the grid information data includes:
[0018] When the number of the energy storage areas exceeds two, determining, according to the grid information data, an energy storage area with the highest electricity price at the current moment and an energy storage area with the lowest electricity price in the energy storage area set;
[0019] Obtaining the absolute value of the electricity price difference between the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price;
[0020] When the absolute value of the electricity price difference is greater than or equal to a preset difference threshold, the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price are determined as the first energy storage area and the second energy storage area that meet the regional coordinated energy storage conditions.
[0021] In the above embodiment, when the energy storage management platform manages more than two energy storage areas, the energy storage management platform selects the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price from each energy storage area for electricity price comparison. Only when the absolute value of the electricity price difference between the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price is greater than or equal to a preset difference threshold is the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price determined as the first energy storage area and the second energy storage area that meet the regional energy storage cooperation conditions. This can maximize the electricity price difference between the determined first energy storage area and the second energy storage area, further improving the profitability of regional energy storage cooperation and significantly increasing the energy storage benefits brought by energy storage applications.
[0022] In some embodiments, the resource exchange direction includes a charging direction and a discharging direction;
[0023] The determining of resource exchange directions of the first energy storage area and the second energy storage area respectively when there are a first energy storage area and a second energy storage area that meet the regional energy storage cooperation conditions includes:
[0024] performing a regional electricity price comparison between the first energy storage area and the second energy storage area based on first grid information data of the first energy storage area and second grid information data of the second energy storage area;
[0025] The resource exchange direction of the energy storage area corresponding to the larger regional electricity price is determined as the discharging direction, and the resource exchange direction of the energy storage area corresponding to the smaller regional electricity price is determined as the charging direction.
[0026] In the above embodiment, by determining the resource exchange direction of the energy storage area corresponding to the larger regional electricity price as the discharge direction, and the resource exchange direction of the energy storage area corresponding to the smaller regional electricity price as the charging direction, when discharging to the regional power grid with the larger regional electricity price, the same discharge amount can be exchanged for more resources, while when charging the energy storage device through the regional power grid with the smaller regional electricity price, more electricity can be exchanged for lower resources, which can greatly improve the profitability of resource exchange.
[0027] In some embodiments, the target energy storage device is an energy storage device corresponding to a regional coordination group, and the method further includes:
[0028] Obtaining a first mapping relationship of the first energy storage area and a second mapping relationship of the second energy storage area; the mapping relationship is used to represent the correspondence between the device groups and device identifiers divided in the energy storage area;
[0029] Based on the first mapping relationship and the second mapping relationship, respectively determine group device identification information corresponding to the area coordination groups in the first energy storage area and the second energy storage area;
[0030] A first target energy storage device in the first energy storage area and a second target energy storage device in the second energy storage area are determined according to the group device identification information.
[0031] In the above embodiment, the mapping relationship can be used to quickly find the first target energy storage device and the second target energy storage device corresponding to the area coordination group from the first energy storage area and the second energy storage area, effectively improving the efficiency and accuracy of determining the target energy storage device.
[0032] In some embodiments, the method further comprises:
[0033] Obtain the energy parameters of each energy storage device in the energy storage area during the current regional coordination cycle;
[0034] The energy storage devices whose energy parameters fall within the preset grouping range are divided into regional coordination groups.
[0035] In the above embodiment, by presetting the grouping interval and comparing the energy parameters of each energy storage device with the preset grouping interval, the energy storage devices belonging to the regional coordination group can be quickly divided, effectively improving the efficiency of device grouping.
[0036] In some embodiments, the method further comprises:
[0037] The energy storage devices whose energy parameters are greater than or equal to the upper limit of the preset grouping interval are divided into a discharge group, wherein the energy storage devices in the discharge group are used to discharge to the regional power grid in the energy storage area during the peak period of the regional power grid;
[0038] The energy storage devices whose energy parameters are less than or equal to the lower limit of the preset grouping interval are divided into charging groups, and the energy storage devices in the charging group are used to charge the energy storage devices during the off-peak period of the regional power grid in the energy storage area.
[0039] In the above embodiment, by dividing the energy storage area into discharge groups and charging groups, the energy storage area can discharge to the regional power grid during the peak period of the corresponding regional power grid, and use the regional power grid to charge the energy storage equipment during the off-peak period of the corresponding regional power grid, thereby effectively improving the energy storage benefits of the energy storage area.
[0040] In some embodiments, the method further comprises:
[0041] Get the exchange duration for resource exchange;
[0042] When the exchange duration reaches a preset exchange duration threshold, the first target energy storage device and the second target energy storage device are controlled to end resource exchange.
[0043] In the above embodiment, by real-time monitoring of the resource exchange duration, when the exchange duration reaches a preset exchange duration threshold, the first target energy storage device and the second target energy storage device can be promptly controlled to terminate the resource exchange, thereby effectively maintaining a high profit rate for regional coordinated energy storage.
[0044] In some embodiments, the method further comprises:
[0045] When the exchange duration does not reach the preset exchange duration threshold, obtaining a first energy storage parameter of the first target energy storage device and a second energy storage parameter of the second target energy storage device;
[0046] When it is determined based on the first energy storage parameter and the second energy storage parameter that both the first target energy storage device and the second target energy storage device meet the resource exchange termination condition, the first target energy storage device and the second target energy storage device are controlled to terminate the resource exchange.
[0047] In the above embodiment, if the exchange duration does not reach the preset exchange duration threshold, the energy storage management platform can monitor the energy storage status of the first target energy storage device and the second target energy storage device in real time. If it is determined that the first target energy storage device and the second target energy storage device both meet the corresponding resource exchange termination conditions, the energy storage management platform can promptly control the first target energy storage device and the second target energy storage device to terminate the resource exchange, effectively improving the operating stability and energy storage safety of the target energy storage devices during the resource exchange process.
[0048] In some embodiments, the method further comprises:
[0049] When the exchange duration does not reach the preset exchange duration threshold, obtaining a first energy storage parameter of the first target energy storage device and a second energy storage parameter of the second target energy storage device;

[0051] Based on the resource exchange direction of the first energy storage area and the second energy storage area, the first newly added target device and the second newly added target device are respectively controlled to perform resource exchange until the exchange duration reaches the preset exchange duration threshold.
[0052] In the above embodiment, if the exchange duration does not reach the preset exchange duration threshold, and both the first target energy storage device and the second target energy storage device meet the resource exchange termination conditions, the energy storage management system can promptly identify a new target device from other device groups, such as the discharge group or the charging group, and control the new target device to continue resource exchange. This can effectively improve the profitability of resource exchange and significantly increase the energy storage benefits brought by energy storage applications.

By having two energy storage areas with an absolute value of the electricity price difference greater than or equal to the preset difference threshold exchange resources with the regional power grid in opposite resource exchange directions, the profit space for resource exchange between energy storage applications and regional power grids can be effectively expanded, the profit rate of resource exchange can be improved, and the energy storage benefits brought by energy storage applications can be significantly improved.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.
[0077] The time-of-use electricity pricing mechanism is a fundamental mechanism currently used in power systems. By setting different electricity price levels for different time periods of the day, the time-of-use electricity price levels can be brought closer to the power system's supply costs. Energy storage applications deployed on both the power supply and user sides are an adjustable and flexible resource application used to fill gaps in the grid's regulation capabilities. To maximize energy storage revenue, energy storage application companies generally control the charging of energy storage devices during periods of low electricity prices and the discharge of energy storage devices into the grid during periods of peak electricity prices. Such control strategies often only focus on price fluctuations during low and peak periods, resulting in limited profit margins and low profit rates, and are unable to significantly increase the energy storage revenue generated by energy storage applications.
[0078] In order to improve the energy storage benefits brought by energy storage applications, regional energy storage cooperation conditions can be pre-set. When there are a first energy storage area and a second energy storage area that meet the regional energy storage cooperation conditions, it indicates that there is an energy storage area pair where the absolute value of the electricity price difference between the two regions is greater than or equal to the preset difference threshold. The two energy storage areas can cooperate with each other to exchange resources with the regional power grid, and the resource exchange directions of the first energy storage area and the second energy storage area are determined respectively. According to their respective resource exchange directions, the first target energy storage device of the first energy storage area and the second target energy storage device of the second energy storage area in the current regional cooperation cycle are controlled respectively, and resources are exchanged with the regional power grid in opposite resource exchange directions. By having two energy storage areas with an absolute price difference greater than or equal to a preset difference threshold exchange resources with the regional power grid in opposite directions, the control strategy can be expanded from focusing only on the lows and peaks of electricity prices in a single area to focusing on the price differences between different areas. As long as the price difference between the areas exceeds the preset difference threshold, resource exchange can be profitable, effectively expanding the profit space of resource exchange between energy storage applications and regional power grids, improving the profit rate of resource exchange, and thus significantly improving the energy storage benefits brought by energy storage applications.
[0079] The energy storage device control method provided in the embodiment of the present application can be applied to Figure 1 In the energy storage application environment shown, the energy storage area 102 is the scene area where the energy storage application is actually performed. The energy storage application enterprise or organization can set up multiple energy storage areas 102 according to the actual energy storage layout, and each energy storage area 102 can be provided with multiple energy storage devices 104.
[0080] Energy storage device 104 is a physical hardware device used for energy storage exchange. In addition to exchanging resources with the user side, energy storage device 104 is also connected to regional power grid 106 via a resource exchange channel, enabling energy exchange with regional power grid 106 to achieve energy storage and energy sharing applications. It is understood that the energy storage device 104 installed in energy storage area 102 will vary depending on the actual application of energy storage. For example, in an electric vehicle energy storage application scenario, energy storage device 104 installed in energy storage area 102 may be an electric vehicle charging device, including a bidirectional charging component and a corresponding charging gun.
[0081] It should be noted that the diagram is based on the example of n energy storage devices 104 in each energy storage area 102. In actual applications, the number of energy storage devices 104 included in each energy storage area 102 may be different. The number of energy storage devices 104 included in each energy storage area 102 can also be determined based on actual energy storage application requirements and the actual creation environment of the energy storage area 102.
[0082] The energy storage management platform 108 can communicate with the energy storage devices 104 in each of the above-mentioned energy storage areas 102 by means of wireless communication. The data storage system can store data that the energy storage management platform 108 needs to process. The data storage system can be integrated on the energy storage management platform 108, or it can be placed on the cloud or other network servers. When the energy storage management system 108 determines that there is a first energy storage area 1021 and a second energy storage area 1022 that meet the regional energy storage conditions in each energy storage area 102, it determines the resource exchange direction of the first energy storage area 1021 and the second energy storage area 1022 respectively, wherein the absolute value of the electricity price difference between the first energy storage area 1021 and the second energy storage area 1022 is greater than or equal to the preset difference threshold. The energy storage management system 108 controls the first target energy storage device 1041 of the first energy storage area 1021 and the second target energy storage device 1042 of the second energy storage area 1022 to exchange resources with the regional power grid 106 in the current regional coordination cycle according to the resource exchange direction of the first energy storage area 1021 and the second energy storage area 1022. It can be understood that the resource exchange direction of the first energy storage area 1021 is opposite to the resource exchange direction of the second energy storage area 1022.
[0083] The energy storage management platform 108 is a platform for managing and controlling the energy storage information of each energy storage area 102. The energy storage management platform 108 can be implemented using an independent server or a server cluster consisting of multiple servers, or can provide management services through cloud services.
[0084] In some embodiments, the energy storage management platform 108 may include a cloud service that provides management services and a monitoring platform. The monitoring platform is used to obtain energy parameters of the energy storage device 104 and monitor energy changes of the energy storage device 104 in real time.
[0085] In some embodiments, as Figure 2 As shown, a method for controlling an energy storage device is provided, which is applied to Figure 1 Taking the energy storage management platform 102 in FIG. 1 as an example, the following steps are included:
[0086] S202: When there are a first energy storage area and a second energy storage area that meet the regional energy storage cooperation conditions, determine the resource exchange direction of the first energy storage area and the second energy storage area respectively; the absolute value of the electricity price difference between the first energy storage area and the second energy storage area is greater than or equal to a preset difference threshold.
[0087] The first energy storage area and the second energy storage area are two target energy storage areas in each energy storage area that meet the regional coordinated energy storage conditions. The regional coordinated energy storage conditions are preset judgment conditions used to determine whether there are energy storage area pairs that can be used for regional coordinated energy storage in each energy storage area managed by the energy storage management platform. If there are first energy storage areas and second energy storage areas that meet the regional coordinated energy storage conditions in each energy storage area, it can be considered that the absolute value of the electricity price difference between the first energy storage area and the second energy storage area is greater than or equal to the preset difference threshold, and the two energy storage areas can cooperate with each other to exchange resources with the regional power grid. It is understandable that the regional coordinated energy storage conditions can be pre-determined by designers or energy storage managers based on the number of energy storage areas actually managed by the energy storage management platform and set in the energy storage management system.
[0088] In some embodiments, each energy storage area may include multiple pairs of energy storage areas that meet the regional energy storage coordination requirements. Each pair includes a first energy storage area and a second energy storage area that mutually meet the regional energy storage coordination requirements. That is, each energy storage area may include multiple first energy storage areas and corresponding multiple second energy storage areas. The first and second energy storage areas in each energy storage area pair can cooperate with each other to exchange resources with the regional power grid.
[0089] Among them, the preset difference threshold is a difference parameter set to determine whether the absolute value of the electricity price difference between energy storage areas can be used for regional coordinated energy storage. The preset difference threshold can be determined by the energy storage management personnel based on the electricity price difference corresponding to each time period between all energy storage areas currently managed by the energy storage management platform. For example, the energy storage management platform can determine the average electricity price difference in each time period based on the electricity price data of each energy storage area in each time period, and determine the average electricity price difference as the preset difference threshold. The preset difference threshold corresponding to each time period is different. The preset difference threshold can also be determined by the energy storage management personnel based on the actual arbitrage needs of the energy storage application scenario. For example, the energy storage management personnel can determine the preset difference threshold q to be 0.2 based on the actual arbitrage needs of the energy storage application scenario. In each subsequent time period, 0.2 can be used as the preset difference threshold to determine whether each energy storage area meets the conditions for regional coordinated energy storage.
[0090] The resource exchange direction is a parameter used to characterize the direction of energy resource flow when the first or second energy storage region exchanges resources with the regional power grid. This direction can include charging and discharging. The charging direction refers to the direction in which energy resources flow from the regional power grid to the energy storage devices in the energy storage region for energy storage, while the discharging direction refers to the direction in which energy resources flow from the energy storage region to the regional power grid for resource exchange.
[0091] In some embodiments, the energy storage management platform determines whether there is a pair of energy storage areas that meets the regional energy storage coordination conditions among the energy storage areas under management based on the regional energy storage coordination conditions. If there is a pair of energy storage areas that meets the regional energy storage coordination conditions, it indicates that there are two energy storage areas in each energy storage area whose absolute value of the electricity price difference is greater than or equal to a preset difference threshold. These two energy storage areas can cooperate with each other to exchange resources with the regional power grid, and the two energy storage areas in the pair of energy storage areas that meet the regional energy storage coordination conditions are respectively determined as the first energy storage area and the second energy storage area.
[0092] S204, based on the resource exchange direction of the first energy storage area and the second energy storage area, respectively controlling the first target energy storage device in the first energy storage area and the second target energy storage device in the second energy storage area in the current regional coordination cycle to exchange resources with the regional power grid; the resource exchange direction of the first energy storage area is opposite to the resource exchange direction of the second energy storage area.
[0093] The current regional coordination cycle refers to the time period during which the first energy storage area and the second energy storage area cooperate with each other and exchange resources with the regional power grid. The specific duration of the current regional coordination cycle can be determined based on the duration during which the absolute value of the electricity price difference between the first energy storage area and the second energy storage area is greater than or equal to a preset difference threshold. For example, if the absolute value of the electricity price difference between the first energy storage area and the second energy storage area is greater than or equal to the preset difference threshold for one hour, then the duration of the current regional coordination cycle is one hour.
[0094] The first target energy storage device in the first energy storage area and the second target energy storage device in the second energy storage area are energy storage devices used to exchange resources with the regional power grid during the current regional coordination cycle. It is understood that the first target energy storage device and the second target energy storage device can be energy storage devices pre-set by the energy storage management personnel for regional coordination, or they can be target energy storage devices determined in real time by the energy storage management platform based on the actual energy storage status of each energy storage device in the first and second energy storage areas before the regional coordination cycle begins.
[0095] In some embodiments, the energy storage management system may search a preset regional compatible energy storage device identification table, and based on the regional compatible energy storage device identification table, determine a preset first target energy storage device in a first energy storage area and a preset second target energy storage device in a second energy storage area.
[0096] In other embodiments, after determining the resource exchange direction between the first energy storage area and the second energy storage area, the energy storage management system can respectively obtain the real-time energy storage parameters of each energy storage device in the first energy storage area and the second energy storage area, and determine the first target energy storage device in the first energy storage area and the second target energy storage device in the second energy storage area based on the resource exchange direction between the first energy storage area and the second energy storage area and the real-time energy storage parameters of each energy storage device.
[0097] In some embodiments, after respectively determining the resource exchange direction of the first energy storage area and the second energy storage area, the energy storage management platform can control the first target energy storage device of the first energy storage area and the second target energy storage device of the second energy storage area to exchange resources with the regional power grid. It should be noted that the resource exchange direction of the first energy storage area is opposite to the resource exchange direction of the second energy storage area. For example, if the resource exchange direction of the first energy storage area is the discharge direction, the resource exchange direction of the second energy storage area is the charging direction. For another example, if the resource exchange direction of the first energy storage area is the charging direction, the resource exchange direction of the second energy storage area is the discharge direction. By controlling the first target energy storage device and the second target energy storage device to exchange resources with the regional power grid in opposite resource exchange directions, the energy storage management platform can achieve regional cooperative arbitrage and increase energy storage revenue.
[0098] In the above-mentioned energy storage device control method, when there are a first energy storage area and a second energy storage area that meet the regional coordinated energy storage conditions, it indicates that there is currently a pair of energy storage areas where the absolute value of the electricity price difference between the regions is greater than or equal to a preset difference threshold. The two energy storage areas can cooperate with each other to exchange resources with the regional power grid, and the resource exchange directions of the first energy storage area and the second energy storage area are respectively determined. According to their respective resource exchange directions, the first target energy storage device of the first energy storage area and the second target energy storage device of the second energy storage area in the current regional coordination cycle are respectively controlled to exchange resources with the regional power grid in opposite resource exchange directions. By having the two energy storage areas with an absolute value of the electricity price difference greater than or equal to the preset difference threshold exchange resources with the regional power grid in opposite resource exchange directions, the profit space for resource exchange between the energy storage application and the regional power grid can be effectively expanded, the profit rate of resource exchange can be improved, and the energy storage benefits brought by the energy storage application can be significantly improved.
[0099] The determination of the first energy storage area and the second energy storage area is the basis for regional coordinated energy storage. In some embodiments, such as Figure 3 As shown, the energy storage device control method further includes the following steps:
[0100] S302: Obtain grid information data of each energy storage area included in the energy storage area set, as well as the area quantity of each energy storage area.
[0101] The energy storage area set is a collection of energy storage areas managed by the energy storage management platform. The grid information data is information data used to represent the regional electricity prices of each energy storage area in the energy storage area set. The grid information data may include regional electricity price data for each energy storage area, as well as information such as electricity price discounts and electricity usage categories for each energy storage area. In some embodiments, the regional electricity price data may be a table showing the relationship between regional electricity prices at various times.
[0102] It is understandable that the grid information data can be data issued by relevant departments based on the time-of-use electricity price mechanism, or it can be information data generated by the energy storage management platform based on the grid information files formulated and issued by relevant departments based on the time-of-use electricity price mechanism.
[0103] In some embodiments, the energy storage management system obtains grid information data of each energy storage area included in the energy storage area set managed by the energy storage management system, as well as the number of energy storage areas included in the energy storage area set.
[0104] S304: Based on the number of energy storage areas and the grid information data, determine whether there is a first energy storage area and a second energy storage area that meet the regional energy storage coordination conditions.
[0105] In some embodiments, the number of regions is different, and the corresponding regional energy storage coordination conditions for determining the first energy storage region and the second energy storage region are also different. Therefore, after obtaining the grid information data of each energy storage region included in the set of energy storage regions managed by the energy storage management system and the number of energy storage regions included in the set of energy storage regions, the energy storage management system can determine the corresponding regional energy storage coordination conditions based on the number of energy storage regions. Based on the grid information data and the regional energy storage coordination conditions, it is determined whether there are a first energy storage region and a second energy storage region that meet the regional energy storage coordination conditions.
[0106] In the above embodiment, the corresponding regional coordinated energy storage conditions are determined by the number of areas in each energy storage area, and then the presence of a first energy storage area and a second energy storage area that meet the regional coordinated energy storage conditions is determined based on the grid information data. This allows accurate selection of the first energy storage area and the second energy storage area that are more suitable for regional coordinated energy storage based on the actual number of areas.
[0107] In some embodiments, based on the number of energy storage areas and grid information data, determining whether there are first energy storage areas and second energy storage areas that meet the regional energy storage cooperation conditions includes:
[0108] If there are two energy storage areas, the electricity price difference between the two energy storage areas is determined based on the grid information data. If the absolute value of the electricity price difference is greater than or equal to a preset difference threshold, the two energy storage areas in the energy storage area set are determined as the first energy storage area and the second energy storage area that meet the regional energy storage coordination conditions.
[0109] In some embodiments, when there are two energy storage areas, the energy storage management platform does not need to consider other factors and only needs to compare the absolute value of the price difference between the two energy storage areas with a preset difference threshold to determine whether the two energy storage areas meet the regional energy storage cooperation conditions. The energy storage management platform determines the current electricity price information of the two energy storage areas based on the current electricity price information of the two energy storage areas, and determines the price difference between the two energy storage areas based on the current electricity price information of the two energy storage areas.
[0110] The energy storage management platform compares the absolute value of the electricity price difference between the two energy storage areas with a preset difference threshold. If the absolute value of the electricity price difference is greater than or equal to the preset difference threshold, it indicates that the two energy storage areas in the energy storage area set meet the regional energy storage coordination conditions, and the two energy storage areas are respectively determined as the first energy storage area and the second energy storage area.
[0111] In some embodiments, when the energy storage management platform determines that the absolute value of the electricity price difference between two energy storage areas is less than a preset difference threshold, it is determined that there are no first energy storage areas and second energy storage areas that meet the regional energy storage coordination conditions in the current regional coordination cycle, and the resource exchange operation of the current regional coordination cycle is terminated, and the regional energy storage coordination conditions are re-determined when entering the next regional coordination cycle.
[0112] In the above embodiment, when the energy storage management platform manages two energy storage areas, it is only necessary to compare the absolute value of the electricity price difference between the two energy storage areas with a preset difference threshold to quickly determine whether the energy storage areas managed by the energy storage management platform meet the regional energy storage matching conditions, further improving the speed and accuracy of determining the first energy storage area and the second energy storage area.
[0113] In other embodiments, Figure 4 As shown, S304, based on the number of energy storage areas and grid information data, determines whether there are a first energy storage area and a second energy storage area that meet the regional energy storage cooperation conditions, including:
[0114] S402 : When the number of energy storage areas exceeds two, determine the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price at the current moment in the energy storage area set based on the grid information data.
[0115] In some embodiments, if the energy storage management platform manages more than two regions, it is possible that the absolute value of the price difference between multiple pairs of energy storage regions will exceed a preset difference threshold. In this case, to maximize profitability, the energy storage management platform must not only consider the comparison of the absolute value of the price difference with the preset difference threshold, but also the size of the price difference between each pair of energy storage regions. Therefore, if the energy storage management platform manages more than two regions, the energy storage management platform can determine the current electricity price information for each energy storage region based on grid information data. Based on this current electricity price information for each energy storage region, the energy storage management platform can determine the energy storage region with the highest electricity price and the energy storage region with the lowest electricity price.
[0116] S404: Obtain the absolute value of the electricity price difference between the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price.
[0117] In some embodiments, the energy storage management platform compares the highest electricity price of the energy storage area with the highest electricity price with the lowest electricity price of the energy storage area with the lowest electricity price to obtain the absolute value of the electricity price difference between the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price.
[0118] S406 , when the absolute value of the electricity price difference is greater than or equal to a preset difference threshold, the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price are determined as the first energy storage area and the second energy storage area that meet the regional energy storage coordination conditions.
[0119] In some embodiments, when the absolute value of the electricity price difference between the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price is greater than or equal to a preset difference threshold, the energy storage management platform can determine the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price as the first energy storage area and the second energy storage area that meet the regional energy storage coordination conditions.
[0120] In some embodiments, when the absolute value of the electricity price difference between the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price is less than a preset difference threshold, it is determined that the first energy storage area and the second energy storage area that meet the regional cooperation energy storage conditions do not exist in the current regional cooperation cycle, the resource exchange operation of the current regional cooperation cycle is terminated, and the regional cooperation energy storage conditions are judged again when entering the next regional cooperation cycle.
[0121] In some embodiments, after determining the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price in the energy storage area set as the first energy storage area and the second energy storage area that meet the regional energy storage matching conditions, the energy storage management platform can modify the status of the determined first energy storage area and the second energy storage area in the energy storage area set to a matching completed state, and then perform regional matching on each energy storage area in the energy storage area set that is in an unmatched state, that is, return to the step of determining whether there are first energy storage areas and second energy storage areas that meet the regional energy storage matching conditions based on the number of areas of each energy storage area and the power grid information data, until there are no energy storage areas that meet the regional energy storage matching conditions in the energy storage area set, or the status of all energy storage areas in the energy storage area set is a matching completed state. By setting a corresponding regional state for each energy storage area in the energy storage area set and performing matching operations for each energy storage area according to the regional state, the number of energy storage area pairs obtained by matching the energy storage area set can be increased, thereby improving the profitability of resource exchange.
[0122] In the above embodiment, when the energy storage management platform manages more than two energy storage areas, the energy storage management platform selects the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price from each energy storage area for electricity price comparison. Only when the absolute value of the electricity price difference between the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price is greater than or equal to a preset difference threshold is the energy storage area with the highest electricity price and the energy storage area with the lowest electricity price determined as the first energy storage area and the second energy storage area that meet the regional energy storage cooperation conditions. This can maximize the electricity price difference between the determined first energy storage area and the second energy storage area, further improving the profitability of regional energy storage cooperation and significantly increasing the energy storage benefits brought by energy storage applications.
[0123] The resource exchange direction of the energy storage area can determine the direction of the flow of electric energy resources during actual resource exchange. In some embodiments, as described above, the resource exchange direction includes a charging direction and a discharging direction. When there are a first energy storage area and a second energy storage area that meet the regional energy storage matching conditions, the resource exchange directions of the first energy storage area and the second energy storage area are determined separately, including:
[0124] Based on the first grid information data of the first energy storage area and the second grid information data of the second energy storage area, the regional electricity prices of the first energy storage area and the second energy storage area are compared. The resource exchange direction of the energy storage area corresponding to the larger regional electricity price is determined as the discharge direction, and the resource exchange direction of the energy storage area corresponding to the smaller regional electricity price is determined as the charge direction.
[0125] The first grid information data is information data used to characterize the regional electricity price of the first energy storage area. The first grid information data may include regional electricity price data for the first energy storage area, such as regional electricity price information for the first energy storage area at various times. Similarly, the second grid information data is information data used to characterize the regional electricity price of the second energy storage area. The second grid information data may include regional electricity price data for the second energy storage area, such as regional electricity price information for the second energy storage area at various times.
[0126] In some embodiments, the energy storage management platform obtains first grid information data of the first energy storage area and second grid information data of the second energy storage area from the grid information data, determines a first regional electricity price of the first energy storage area at the current moment and a second regional electricity price of the second energy storage area at the current moment based on the first grid information data and the second grid information data, compares the regional electricity prices of the first energy storage area and the second energy storage area based on the first regional electricity price and the second regional electricity price, and determines a larger regional electricity price and a smaller regional electricity price.
[0127] The energy storage management platform determines the resource exchange direction for energy storage areas with higher regional electricity prices as discharge, and for energy storage areas with lower regional electricity prices as charge. During resource exchange, the energy storage areas with higher regional electricity prices will transfer stored energy to the regional power grid for resource exchange, while the energy storage areas with lower regional electricity prices will exchange resources with the regional power grid and obtain energy from the regional power grid for storage.
[0128] In the above embodiment, by determining the resource exchange direction of the energy storage area corresponding to the larger regional electricity price as the discharge direction, and the resource exchange direction of the energy storage area corresponding to the smaller regional electricity price as the charging direction, when discharging to the regional power grid with the larger regional electricity price, the same discharge amount can be exchanged for more resources, while when charging the energy storage device through the regional power grid with the smaller regional electricity price, more electricity can be exchanged for lower resources, which can greatly improve the profitability of resource exchange.
[0129] The target energy storage device is the main execution device that actually performs the resource exchange operation. In some embodiments, such as Figure 5 As shown, the target energy storage device is the energy storage device corresponding to the regional coordination group, and the energy storage device control method further includes the following steps:
[0130] S502: Acquire a first mapping relationship of the first energy storage area and a second mapping relationship of the second energy storage area.
[0131] The mapping relationship is used to represent the correspondence between the device groups and device identifiers within the energy storage area. The first mapping relationship for the first energy storage area can represent the correspondence between the device groups and device identifiers within the first energy storage area. Similarly, the second mapping relationship for the second energy storage area can represent the correspondence between the device groups and device identifiers within the second energy storage area.
[0132] In some embodiments, the energy storage region mapping relationship can be obtained based on the actual energy storage parameters of each energy storage device in the energy storage region before entering the current region coordination cycle. Before entering the current region coordination cycle, the energy storage management platform obtains the actual energy storage parameters of each energy storage device in the first energy storage region and the second energy storage region, divides each energy storage device into a corresponding device group based on the actual energy storage parameters, and generates a mapping relationship between the energy storage regions based on each device group and the device identifiers of the energy storage devices included in each device group.
[0133] In some embodiments, the energy storage management platform obtains a first mapping relationship of the first energy storage area and a second mapping relationship of the second energy storage area.
[0134] S504 : Based on the first mapping relationship and the second mapping relationship, determine group device identification information corresponding to the area coordination groups in the first energy storage area and the second energy storage area respectively.
[0135] The regional coordination group is a special group for regional coordinated energy storage, and the group device identification information corresponding to the regional coordination group can be used to represent the device identification information of the energy storage devices included in the regional coordination group.
[0136] In some embodiments, the energy storage devices included in the regional coordination group can be considered as energy storage devices with moderate energy storage capacity. In this way, when regional coordinated energy storage is required, regardless of whether the resource exchange direction determined by the energy storage area is the discharge direction or the charging direction, the energy storage devices in the regional coordination group can complete the resource exchange in accordance with the corresponding resource exchange direction.
[0137] In some embodiments, the energy storage devices included in the regional coordination group may be composed of energy storage devices with moderate energy storage, as well as some energy storage devices with higher and lower energy storage. When the energy storage management platform assigns energy storage devices to the corresponding groups for the regional coordination groups, it prioritizes assigning energy storage devices with moderate energy storage to the regional coordination groups and simultaneously determines the number of energy storage devices with moderate energy storage. If the number of energy storage devices with moderate energy storage does not reach a preset threshold, the energy storage management platform may extract some energy storage devices with higher and lower energy storage from other groups according to a preset extraction method, and these energy storage devices, together with the energy storage devices with moderate energy storage, constitute the group of devices corresponding to the regional coordination group.
[0138] In some embodiments, after obtaining the first mapping relationship and the second mapping relationship, the energy storage management platform can determine the group device identification information corresponding to the regional coordination group in the first energy storage area based on the first mapping relationship, and determine the group device identification information corresponding to the regional coordination group in the second energy storage area based on the second mapping relationship.
[0139] S506 : Determine a first target energy storage device in the first energy storage area and a second target energy storage device in the second energy storage area according to the group device identification information.
[0140] In some embodiments, the energy storage management platform searches for an energy storage device corresponding to the group device identification information in the first energy storage area based on the group device identification information corresponding to the regional pairing group, and determines the energy storage device corresponding to the group device identification information as the first target energy storage device in the first energy storage area. Similarly, the energy storage management platform searches for an energy storage device corresponding to the group device identification information in the second energy storage area, and determines the energy storage device corresponding to the group device identification information as the second target energy storage device in the second energy storage area.
[0141] In the above embodiment, the mapping relationship can be used to quickly find the first target energy storage device and the second target energy storage device corresponding to the area coordination group from the first energy storage area and the second energy storage area, effectively improving the efficiency and accuracy of determining the target energy storage device.
[0142] Furthermore, in some embodiments, the energy storage device control method further includes:
[0143] Obtain the energy parameters of each energy storage device within the energy storage area during the current regional coordination cycle. Assign energy storage devices whose energy parameters fall within a preset grouping range to regional coordination groups.
[0144] The energy parameter of an energy storage device is an indicator parameter used to characterize the current amount of stored energy in the energy storage device. For example, the energy parameter can be the SOC (State of Charge) or SOE (State of Energy) of the energy storage device. A larger energy parameter value indicates that the corresponding energy storage device stores more energy and has a smaller storage capacity. Conversely, a smaller energy parameter value indicates that the corresponding energy storage device stores less energy and has a larger storage capacity.
[0145] The preset grouping interval is a preset interval range used to divide equipment groups. The preset grouping interval can be preset by the energy storage management personnel based on actual energy storage needs.
[0146] In some embodiments, the energy storage management platform can obtain the energy parameters of each energy storage device in the first energy storage area and the second energy storage area in the current regional coordination cycle, and compare the energy parameters of each energy storage device with the preset grouping interval. If the energy parameters of the energy storage device belong to the preset grouping interval, it means that the storage energy of the energy storage device is moderate, and the energy storage device can be divided into the regional coordination group.
[0147] In the above embodiment, by presetting the grouping interval and comparing the energy parameters of each energy storage device with the preset grouping interval, the energy storage devices belonging to the regional coordination group can be quickly divided, effectively improving the efficiency of device grouping.
[0148] In addition to regional coordination groups, in order to ensure the normal use of the energy storage area, equipment groups can also include discharge groups and charging groups.
[0149] In some embodiments, the energy storage device control method further includes:
[0150] Energy storage devices with energy parameters greater than or equal to the upper limit of the preset grouping interval are divided into the discharge group, and energy storage devices with energy parameters less than or equal to the lower limit of the preset grouping interval are divided into the charging group.
[0151] Among them, the energy storage equipment in the discharge group is used to discharge the regional power grid during the peak period of the regional power grid in the energy storage area, and the energy storage equipment in the charging group is used to charge the energy storage equipment during the off-peak period of the regional power grid in the energy storage area.
[0152] In some embodiments, the energy storage management platform compares the energy parameters of the energy storage devices with a preset grouping interval. If the energy parameter is greater than or equal to the preset grouping area upper limit, it indicates that the energy storage device has a high stored energy and can be used to discharge to the regional power grid during peak hours in the energy storage area to improve profitability. Therefore, the energy storage management platform can classify energy storage devices with energy parameters greater than or equal to the preset grouping interval upper limit into a discharge group.
[0153] Similarly, if the energy parameter is less than or equal to the preset lower limit for the grouping area, it indicates that the energy storage device has low stored energy and high storage capacity, and can be used to charge the regional power grid during off-peak periods in the energy storage area, thereby increasing profitability. Therefore, the energy storage management platform can classify energy storage devices with energy parameters less than or equal to the preset lower limit for the grouping area into charging groups.
[0154] In the above embodiment, by dividing the energy storage area into discharge groups and charging groups, the energy storage area can discharge to the regional power grid during the peak period of the corresponding regional power grid, and use the regional power grid to charge the energy storage equipment during the off-peak period of the corresponding regional power grid, thereby effectively improving the energy storage benefits of the energy storage area.
[0155] In order to further maintain a high profit rate, in some embodiments, the energy storage device control method further includes:
[0156] An exchange duration for resource exchange is acquired, and when the exchange duration reaches a preset exchange duration threshold, the first target energy storage device and the second target energy storage device are controlled to end the resource exchange.
[0157] The preset exchange duration threshold is a preset termination condition parameter used to determine whether the resource exchange needs to be terminated.
[0158] In some embodiments, the preset exchange duration threshold can be determined based on the duration of the current regional coordination cycle. Specifically, it can be determined based on the length of time that the absolute value of the electricity price difference between the first energy storage area and the second energy storage area is greater than or equal to the preset difference threshold. For example, if the absolute value of the electricity price difference between the first energy storage area and the second energy storage area is greater than or equal to the preset difference threshold for one hour, the preset exchange duration threshold can be set to one hour.
[0159] In some embodiments, when controlling the first target energy storage device and the second target energy storage device to execute resource exchange, the energy storage management platform can obtain the exchange duration of the resource exchange in real time and compare the exchange duration with a preset exchange duration threshold. If the exchange duration reaches the preset exchange duration threshold, it indicates that the absolute value of the subsequent electricity price difference between the first energy storage area and the second energy storage area may not be greater than or equal to the preset difference threshold, and continuing the resource exchange may reduce the profit rate of the resource exchange. Therefore, the energy storage management platform will control the first target energy storage device and the second target energy storage device to terminate the resource exchange.
[0160] In the above embodiment, by real-time monitoring of the resource exchange duration, when the exchange duration reaches a preset exchange duration threshold, the first target energy storage device and the second target energy storage device can be promptly controlled to terminate the resource exchange, thereby effectively maintaining a high profit rate for regional coordinated energy storage.
[0161] In some other embodiments, the energy storage device control method further includes:
[0162] If the exchange duration does not reach a preset exchange duration threshold, a first energy storage parameter of the first target energy storage device and a second energy storage parameter of the second target energy storage device are obtained. If it is determined based on the first energy storage parameter and the second energy storage parameter that both the first target energy storage device and the second target energy storage device meet a resource exchange termination condition, the first target energy storage device and the second target energy storage device are controlled to terminate the resource exchange.
[0163] The first energy storage parameter and the second energy storage parameter are indicator parameters for respectively characterizing the real-time storage energy size of the first target energy storage device and the real-time storage energy size of the second target energy storage device.
[0164] The resource exchange termination condition is a judgment condition used to determine whether the first target energy storage device or the second target energy storage device has reached its energy storage limit. It will be understood that the resource exchange termination condition corresponding to a target energy storage device is related to its corresponding resource exchange direction. For example, if the resource exchange direction corresponding to the first target energy storage device is discharging and the resource exchange direction corresponding to the second target energy storage device is charging, the resource exchange termination condition for the first target energy storage device can be determined as the first target energy storage device's first energy storage parameter being less than or equal to a preset discharge threshold. The preset discharge threshold can be the lower limit of a preset grouping interval. The resource exchange termination condition for the second target energy storage device can be determined as the second target energy storage device's second energy storage parameter being greater than or equal to a preset charge threshold. The preset charge threshold can be the upper limit of a preset grouping interval. Conversely, if the resource exchange direction corresponding to the first target energy storage device is charging and the resource exchange direction corresponding to the second target energy storage device is discharging, the resource exchange termination condition for the first target energy storage device can be determined as the second target energy storage device's second energy storage parameter being less than or equal to the preset discharge threshold. The resource exchange termination condition for the first target energy storage device can be determined as the first target energy storage device's first energy storage parameter being greater than or equal to the preset charge threshold.
[0165] In some embodiments, if the energy storage management platform determines that the exchange duration has not reached a preset exchange duration threshold, it may obtain a first energy storage parameter of the first target energy storage device and a second energy storage parameter of the second target energy storage device, and determine whether both the first target energy storage device and the second target energy storage device meet corresponding resource exchange termination conditions based on the first energy storage parameter and the second energy storage parameter, as well as the resource exchange directions corresponding to the first target energy storage device and the second target energy storage device. If it is determined that both the first target energy storage device and the second target energy storage device meet corresponding resource exchange termination conditions, the energy storage management platform may control the first target energy storage device and the second target energy storage device to terminate the resource exchange.
[0166] In the above embodiment, if the exchange duration does not reach the preset exchange duration threshold, the energy storage management platform can monitor the energy storage status of the first target energy storage device and the second target energy storage device in real time. If it is determined that the first target energy storage device and the second target energy storage device both meet the corresponding resource exchange termination conditions, the energy storage management platform can promptly control the first target energy storage device and the second target energy storage device to terminate the resource exchange, effectively improving the operating stability and energy storage safety of the target energy storage devices during the resource exchange process.
[0167] In order to further improve the profitability of resource exchange, in some embodiments, Figure 6 As shown, the energy storage device control method further includes the following steps:
[0168] S602 : When the exchange duration does not reach a preset exchange duration threshold, obtain a first energy storage parameter of the first target energy storage device and a second energy storage parameter of the second target energy storage device.
[0169] In some embodiments, if the energy storage management platform determines that the exchange duration has not reached a preset exchange duration threshold, it can obtain a first energy storage parameter of the first target energy storage device and a second energy storage parameter of the second target energy storage device. It is understood that the specific definitions of the first energy storage parameter and the second energy storage parameter can be found in the previous description and are not further elaborated here.
[0170] S604, when it is determined based on the first energy storage parameter and the second energy storage parameter that the first target energy storage device and the second target energy storage device both meet the resource exchange end condition, determine the first newly added target device and the second newly added target device from other device groups based on the first mapping relationship and the second mapping relationship, as well as the resource exchange direction.
[0171] Other equipment groups include discharge and charge groups. Energy storage devices in the discharge group are those with high energy storage capacity and are generally used to discharge energy to the regional grid during peak hours. Energy storage devices in the charge group are those with low energy storage capacity and are generally used to charge energy storage devices during off-peak hours.
[0172] In some embodiments, the energy storage management platform determines whether the first target energy storage device and the second target energy storage device both meet the corresponding resource exchange termination conditions based on the first energy storage parameter and the second energy storage parameter, and then determines the first newly added target device and the second newly added target device from other groups based on the first mapping relationship and the second mapping relationship, as well as the resource exchange direction.
[0173] In some embodiments, when the resource exchange direction corresponding to the first target energy storage device is the discharging direction, and the resource exchange direction corresponding to the second target energy storage device is the charging direction, the energy storage management platform can determine the energy storage device groups corresponding to the charging group in the first energy storage area based on the first mapping relationship, and determine the first newly added target device from the energy storage device groups based on a preset addition method. Simultaneously, the energy storage device groups corresponding to the discharging group in the second energy storage area can be determined based on the second mapping relationship, and determine the second newly added target device from the energy storage device groups based on the preset addition method.
[0174] Conversely, in other embodiments, when the resource exchange direction corresponding to the first target energy storage device is charging, and the resource exchange direction corresponding to the second target energy storage device is discharging, the energy storage management platform can determine the energy storage device groups corresponding to the discharging group in the first energy storage area based on the first mapping relationship, and determine the first newly added target device from the energy storage device groups based on a preset addition method. Simultaneously, the energy storage device groups corresponding to the charging group in the second energy storage area can be determined based on the second mapping relationship, and determine the second newly added target device from the energy storage device groups based on the preset addition method.
[0175] It is understood that the preset addition method can be determined based on actual energy storage needs. For example, the preset addition method can be to randomly select a preset number of groups of energy storage devices from each group of energy storage devices as new target devices. Alternatively, the preset addition method can be to determine the group of energy storage devices with the highest or lowest stored energy as the new target devices.
[0176] S606: Based on the resource exchange direction of the first energy storage area and the second energy storage area, respectively control the first newly added target device and the second newly added target device to exchange resources until the exchange duration reaches a preset exchange duration threshold.
[0177] In some embodiments, after determining the first newly added target device and the second newly added target device, the energy storage management platform controls the first newly added target device and the second newly added target device to exchange resources based on the resource exchange direction of the first energy storage area and the second energy storage area, respectively, until the exchange duration reaches a preset exchange duration threshold.
[0178] In some embodiments, if both the first newly added target device and the second newly added target device meet the corresponding resource exchange termination conditions, the energy storage management platform may update the first newly added target device and the second newly added target device to the first target device and the second target device, and return to execute S602, that is, if the exchange duration does not reach the preset exchange duration threshold, obtain the first energy storage parameter of the first target energy storage device and the second energy storage parameter of the second target energy storage device until the exchange duration reaches the preset exchange duration threshold.
[0179] In the above embodiment, if the exchange duration does not reach the preset exchange duration threshold, and both the first target energy storage device and the second target energy storage device meet the resource exchange termination conditions, the energy storage management system can promptly identify a new target device from other device groups, such as the discharge group or the charging group, and control the new target device to continue resource exchange. This can effectively improve the profitability of resource exchange and significantly increase the energy storage benefits brought by energy storage applications.
[0180] In some embodiments, a method for controlling an energy storage device is provided, which is described by taking the application of the energy storage device control method to an energy storage sharing application scenario of an electric vehicle as an example.
[0181] The energy storage sharing application scenarios of electric vehicles can be as follows: Figure 7 As shown, each energy storage device can be considered an energy storage node. The energy storage device includes a communication-connected energy storage device and a charging device. The energy storage device is equipped with a wireless communication device, which can communicate with the cloud service through the wireless communication device. One side of the charging device is connected to an external device charging gun, which can be used to convert electrical energy resources with the electric vehicle through the charging gun. The charging device can also exchange resources with the power grid. The cloud service in the energy storage management platform can communicate with each energy storage device in multiple energy storage areas. At the same time, the cloud service also communicates with the monitoring platform, which can monitor the energy changes of each energy storage device in real time.
[0182] In order to clearly describe the technical solution of this embodiment, the energy storage area managed by the energy storage management platform only includes two energy storage areas, namely area A and area B. Figure 8 As shown, the energy storage device control method specifically includes the following steps:
[0183] S801: The energy storage management platform obtains regional electricity price information for region A and region B.
[0184] S802 : Determine the regional electricity prices of region A and region B in each time period according to regional electricity price information.
[0185] S803, calculating the electricity price difference between area A and area B in each time period.
[0186] S804: When the absolute value of the electricity price difference in a certain period is greater than or equal to a preset difference threshold, it is determined that region A and region B meet the regional coordinated energy storage conditions in the regional coordinated period.
[0187] In this embodiment, the energy storage management platform may determine a period during which the absolute value of the electricity price difference is greater than or equal to a preset difference threshold as a regional coordination period, and the period length N of the regional coordination period is equal to the length of the period.
[0188] S805: When the absolute value of the electricity price difference in each time period is less than the preset difference threshold, it is determined that area A and area B do not meet the regional energy storage cooperation conditions, and the resource exchange task between area A and area B is terminated. The step S801 is executed again after the regional electricity price information of area A and area B is updated.
[0189] S806 , obtaining the SOC value of each energy storage device in area A and area B at a preset time before entering the area coordination cycle.
[0190] S807 , compare the SOC value of each energy storage device with the preset grouping interval [n1, n2], divide the energy storage devices with SOC≥n1 into group 1, divide the energy storage devices with SOC≤n2 into group 2, and divide the energy storage devices with n1>SOC>n2 into group 3.
[0191] Among them, Figure 9 As shown, the device groups include Group 1, Group 2, and Group 3. Group 1 is the discharge group, used to discharge energy from the storage area to the grid during peak hours in the corresponding regional grid. Group 2 is the charge group, used to charge the energy storage from the grid during off-peak hours in the corresponding regional grid. Group 3 is the regional cooperation group, used to cooperate with other regions to achieve electricity price arbitrage.
[0192] S808 , entering the current regional coordination cycle, and determining the resource exchange direction between region A and region B based on the regional electricity prices of region A and region B.
[0193] S809 , controlling each energy storage device of group 3 in region A and each energy storage device of group 3 in region B to exchange resources with the regional power grid according to their corresponding resource exchange directions.
[0194] S810: Obtain the exchange duration of the resource exchange and determine whether the exchange duration lasts for N hours.
[0195] S811: When the exchange duration lasts for N hours, the energy storage devices in area A and area B are regrouped, and the resource exchange task is terminated.
[0196] S812: If the exchange duration does not reach N hours, return to step S808.
[0197] The following example illustrates regional energy storage integration. For example, the regional power grid in Region A operates during peak and valley periods: 7:00 AM to 10:00 AM and 7:00 PM to 11:00 PM daily, normal hours from 11:00 AM to 7:00 PM, and off-peak hours from 11:00 PM to 7:00 AM the following day. The regional power grid in Region B operates during peak and valley periods: 8:00 AM to 11:00 AM and 11:00 AM to 9:00 PM daily, off-peak hours from 10:00 PM to 5:00 AM the following day, and normal hours for the remainder of the day. All times are in Beijing time.
[0198] During the period from 7:00 to 8:00, the regional power grid corresponding to area A is in peak hours, while the regional power grid corresponding to area B is in normal hours. As long as the absolute value of the price difference between the two regions is greater than or equal to the preset difference threshold, such as the absolute value of the price difference ≥ 0.2 yuan, the energy storage devices in group 3 in area A can be controlled to discharge during this period, and the energy storage devices in group 3 in area B can be controlled to charge during this period, achieving electricity price arbitrage.
[0199] Similarly, during the period from 22:00 to 23:00, the regional power grid corresponding to area A is in peak period, while the regional power grid corresponding to area B is in off-peak period. As long as the absolute value of the price difference between the two regional electricity prices is greater than or equal to the preset difference threshold, the energy storage devices in group 3 in area A can be controlled to discharge during this period, and the energy storage devices in group 3 in area B can be controlled to charge during this period, thereby achieving electricity price arbitrage.
[0200] During the period from 10:00 to 11:00, the regional power grid corresponding to area A is in normal hours, and the regional power grid corresponding to area B is in peak hours. As long as the absolute value of the price difference between the two regional electricity prices is greater than or equal to the preset difference threshold, the energy storage devices in group 3 in area A can be controlled to charge during this period, and the energy storage devices in group 3 in area B can be controlled to discharge during this period, achieving electricity price arbitrage.
[0201] In this embodiment, by dividing the energy storage equipment in each region into three groups, it is possible to use the energy storage equipment in Group 1 and Group 2 for electricity price arbitrage when the respective energy storage region is in the peak period or the grid off period. At the same time, the energy storage equipment in different regions can be coordinated. By using regional energy storage, peak-valley arbitrage can be carried out at all times by taking advantage of the peak and valley periods in different regions. This can effectively expand the profit space for resource exchange between energy storage applications and regional power grids, improve the profit rate of resource exchange, and thus significantly increase the energy storage benefits brought by energy storage applications.
