Description

Technical Field

[0001] This invention belongs to the field of power supply technology, and in particular relates to a method and system for collaborative management and control of distributed energy storage devices in power distribution networks. Background Technology

[0002] To achieve coordinated scheduling of distributed energy storage devices in the power distribution network, the invention patent application CN114374273A, "Distributed Energy Storage System," utilizes a cloud server to issue control commands based on data collected by the data acquisition module. The received control commands are then used by an industrial control computer to control the energy storage units to store and output electrical energy. However, the above technical solution has the following technical problems: When conducting collaborative management and control of distributed energy storage devices, in some energy storage regulation scenarios with extremely high power regulation requirements, only one or two energy storage devices may have enough power to meet the energy storage regulation needs. Therefore, how to control and process the energy storage devices with sufficient power to meet the energy storage regulation needs in such scenarios, thereby ensuring the reliability of energy storage regulation, has become an urgent technical problem to be solved.

[0003] To address the aforementioned technical problems, this invention provides a method and system for collaborative management and control of distributed energy storage devices in power distribution networks. Summary of the Invention

[0004] To achieve the objectives of this invention, the following technical solution is adopted: According to one aspect of the present invention, a method for collaborative management and control of distributed energy storage devices in a power distribution network is provided.

[0005] A collaborative management and control method for distributed energy storage devices in a power distribution network, specifically including: Based on the energy storage regulation demand data in the distribution network area, the energy storage regulation time period data in different energy storage regulation power ranges are determined. Based on the adaptation of distributed energy storage devices in the distribution network in each energy storage regulation power range, the adaptation deviation range in the energy storage regulation power range is determined. Based on the energy storage regulation data in the adaptation deviation range, the control energy storage device in the distributed energy storage device is determined. Based on the energy storage regulation time period data in the adaptation deviation range and the energy storage regulation data of the controlled energy storage device in different remaining capacity ranges, the energy storage regulation control strategy of the controlled energy storage device in different remaining capacity ranges is determined. With the energy storage regulation control strategy and the adaptation deviation range as constraints, based on the energy storage regulation processing requirements and the remaining capacity range of the distributed energy storage device, the collaborative regulation processing strategy that does not belong to the controlled energy storage device is determined.

[0006] The beneficial effects of this invention are as follows: Based on the energy storage adjustment period data within the adaptation deviation range and the energy storage adjustment data of the controlled energy storage device in different remaining capacity ranges, the energy storage adjustment control strategy for the controlled energy storage device in different remaining capacity ranges is determined. This takes into account both the number of energy storage adjustments made by the controlled energy storage device in the remaining capacity range and the reliability of the verification processing results of the control energy storage device in the remaining capacity range. Furthermore, by combining the energy storage adjustment period data within the adaptation deviation range and considering the energy storage adjustment demand corresponding to the adaptation deviation range, the energy storage adjustment control strategy for different remaining capacity ranges is determined based on the energy storage adjustment demand and the reliability of the verification processing results, thus ensuring the reliability of the verification processing of the controlled energy storage device in different remaining capacity ranges.

[0007] Using energy storage regulation and control strategies and adaptation deviation ranges as constraints, and based on energy storage regulation and processing requirements and the remaining capacity range of distributed energy storage devices, a collaborative regulation and processing strategy for energy storage devices not subject to control is determined. This avoids the technical problem that other energy storage devices cannot respond in a timely and effective manner when the energy storage regulation reliability of the controlled energy storage devices is poor within the adaptation deviation range, which would prevent energy storage devices not subject to energy storage regulation and control from being refrained from being regulated and controlled. This further improves the reliability of energy storage regulation and processing within the adaptation deviation range.

[0008] Furthermore, the energy storage regulation demand data includes the energy storage regulation time periods in the distribution network and the energy storage regulation power ranges for different energy storage regulation time periods.

[0009] Furthermore, the energy storage regulation power range is obtained by dividing the range into equal intervals based on a preset power. In one possible embodiment, the preset power is 20KW.

[0010] Furthermore, the method for determining the adaptation deviation range within the energy storage regulation power range is as follows: Based on the adaptation of distributed energy storage devices in the power distribution network to energy storage regulation in various energy storage regulation power ranges, the energy storage regulation data of the distributed energy storage devices in the energy storage regulation power ranges are determined. Based on the energy storage regulation data, suitable distributed energy storage devices within the energy storage regulation power range are determined; Based on the distribution data of the adapted distributed energy storage devices within the energy storage regulation power range, it is determined whether the energy storage regulation power range is an adaptation deviation range.

[0011] Furthermore, the method for determining the coordinated regulation and processing strategy that does not belong to the control of energy storage devices is as follows: Based on the energy storage regulation and control strategy, determine the remaining capacity range of the energy storage device when the preset regulation and control strategy is adopted; The remaining capacity range of the control energy storage device is determined based on the remaining capacity range of the distributed energy storage device. Based on the remaining capacity range of the energy storage device using the preset adjustment control strategy, and the historical adjustment data of the remaining capacity range of the energy storage device within the adaptation deviation range, it is determined that when there is an energy storage adjustment demand, the coordinated adjustment processing strategy of the energy storage device is not applicable to the energy storage device.

[0012] On the other hand, the present invention provides a computer system comprising: a memory and a processor connected in communication, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the above-described method for collaborative management and control of distributed energy storage devices in a power distribution network when running the computer program.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0018] For ease of understanding, the following will describe the scheme through Embodiment 1 and Embodiment 2. In this application, when there are only one or two energy storage devices in the distribution network that can meet the energy storage regulation power requirements of the high energy storage regulation power range, the energy storage devices are controlled during energy storage regulation, thereby ensuring the reliability of energy storage regulation in the high energy storage regulation power range.

[0019] Example 1 To solve the above problems, according to one aspect of the present invention, such as Figure 1 As shown, according to one aspect of the present invention, a method for collaborative management and control of distributed energy storage devices in a power distribution network is provided, specifically including: Based on the energy storage regulation demand data in the distribution network area, the energy storage regulation time period data in different energy storage regulation power ranges are determined. Based on the adaptation of distributed energy storage devices in the distribution network in each energy storage regulation power range, the adaptation deviation range in the energy storage regulation power range is determined. Based on the energy storage regulation data in the adaptation deviation range, the control energy storage device in the distributed energy storage device is determined. Furthermore, the energy storage regulation demand data includes the energy storage regulation time periods in the distribution network and the energy storage regulation power ranges for different energy storage regulation time periods.

[0020] Furthermore, the energy storage regulation power range is obtained by dividing the range into equal intervals based on a preset power. In one possible embodiment, the preset power is 20KW.

[0021] Specifically, such as Figure 2 As shown, the method for determining the adaptation deviation range in the energy storage regulation power range is as follows: Based on the adaptation of distributed energy storage devices in the power distribution network to energy storage regulation in various energy storage regulation power ranges, the energy storage regulation data of the distributed energy storage devices in the energy storage regulation power ranges are determined. Based on the energy storage regulation data, suitable distributed energy storage devices within the energy storage regulation power range are determined; Based on the distribution data of the adapted distributed energy storage devices within the energy storage regulation power range, it is determined whether the energy storage regulation power range is an adaptation deviation range.

[0022] It should be noted that the compatible distributed energy storage devices within the energy storage regulation power range are distributed energy storage devices whose energy storage regulation power range falls within the rated energy storage regulation power.

[0023] It should be noted that when the number of compatible distributed energy storage devices within the energy storage regulation power range meets the requirements and the line loss data between the device and different distribution substations all meet the requirements, then the energy storage regulation power range is determined not to be an adaptation deviation range.

[0024] In one possible specific embodiment, if the line loss rate of the adapted distributed energy storage device is less than 10% in different distribution zones and the number of distributed energy storage devices is not less than 3, then it is determined that the energy storage regulation power range does not belong to the adaptation deviation range.

[0025] Optionally, the method for determining the adaptation deviation range in the energy storage regulation power range is as follows: Based on the adaptation of distributed energy storage devices in the power distribution network to energy storage regulation in various energy storage regulation power ranges, the energy storage regulation data of the distributed energy storage devices in the energy storage regulation power ranges are determined. Based on the energy storage regulation data, suitable distributed energy storage devices within the energy storage regulation power range are determined; Based on the data of the adapted distributed energy storage devices within the energy storage regulation power range, determine whether the energy storage regulation power range is an adaptation deviation range.

[0026] Specifically, when the number of compatible distributed energy storage devices within the energy storage regulation power range is less than a preset threshold for the number of energy storage devices, for example, no more than 2, the energy storage regulation power range is determined to be an adaptation deviation range because the number of compatible distributed energy storage devices within the energy storage regulation power range is small.

[0027] Specifically, such as Figure 3 As shown, the method for determining the control energy storage device in the distributed energy storage device is as follows: Based on the energy storage regulation data within the adaptation deviation range, the energy storage regulation period data of the distributed energy storage device within the adaptation deviation range is determined; Based on the energy storage adjustment period data, determine the energy storage adjustment period data within the adaptation deviation range in different remaining capacity ranges; By using energy storage adjustment time data within the adaptation deviation range in different remaining capacity ranges, the control energy storage device in the distributed energy storage device is determined.

[0028] It should be noted that when there is only one distributed energy storage device that is adapted within the adaptation deviation range, the distributed energy storage device that is adapted within the adaptation deviation range is determined to be a control energy storage device. Additionally, it can be understood that when there is more than one distributed energy storage device adapted within the adaptation deviation range, based on the data of energy storage adjustment periods within the adaptation deviation range in different remaining capacity ranges, the distributed energy storage device adapted within the adaptation deviation range with the fewest remaining capacity ranges containing the fewest energy storage adjustment periods is designated as the control energy storage device. For example, the distributed energy storage device adapted within the adaptation deviation range with the fewest remaining capacity ranges containing fewer than 10 energy storage adjustment periods is designated as the control energy storage device.

[0029] Based on the energy storage regulation time period data in the adaptation deviation range and the energy storage regulation data of the controlled energy storage device in different remaining capacity ranges, the energy storage regulation control strategy of the controlled energy storage device in different remaining capacity ranges is determined. With the energy storage regulation control strategy and the adaptation deviation range as constraints, based on the energy storage regulation processing requirements and the remaining capacity range of the distributed energy storage device, the collaborative regulation processing strategy that does not belong to the controlled energy storage device is determined.

[0030] Optionally, the method for determining the energy storage regulation and control strategy of the energy storage device in different remaining capacity ranges is as follows: Based on the data of energy storage adjustment periods within the adaptation deviation range, the distribution data of energy storage adjustment periods within the adaptation deviation range on different dates is determined. Based on the distribution data, the dates on which energy storage adjustment periods exist within the adaptation deviation range are determined and used as the adaptation adjustment dates. Based on the energy storage adjustment data of the controlled energy storage device within the remaining capacity range, determine the energy storage adjustment period data within the adaptation deviation range within the remaining capacity range; Based on the energy storage adjustment period data within the remaining capacity range and the adaptation deviation range, a distribution aggregation value is determined. Using the distribution aggregation value and the adaptation adjustment date data, an energy storage adjustment control strategy for the controlled energy storage device within the remaining capacity range is determined.

[0031] It is understandable that when the proportion of the number of adaptation adjustment dates in the most recent preset time period is greater than the preset proportion threshold, it indicates that there are a large number of energy storage adjustment periods in the adaptation deviation range. Therefore, a preset adjustment control strategy is adopted in different remaining capacity ranges to determine the energy storage adjustment control strategy of the energy storage device.

[0032] Additionally, it can be understood that when the proportion of the number of the adaptation adjustment dates within the most recent preset time period is not greater than a preset proportion threshold, and when the distribution aggregation value is less than a preset aggregation threshold, for example, less than 0.6, then it is determined that a preset adjustment control strategy will be adopted within the remaining capacity range, and the energy storage adjustment control strategy of the energy storage device is determined.

[0033] Furthermore, when the distribution aggregation value is not less than a preset aggregation threshold, a second preset regulation and control strategy is determined to be adopted within the remaining capacity range, thus determining the energy storage regulation and control strategy for the energy storage device.

[0034] Furthermore, the method for determining the energy storage regulation and control strategy of the energy storage device within different remaining capacity ranges is as follows: Based on the data of energy storage adjustment periods within the adaptation deviation range, the distribution data of energy storage adjustment periods within the adaptation deviation range on different dates is determined. Based on the distribution data, the dates on which energy storage adjustment periods exist within the adaptation deviation range are determined and used as the adaptation adjustment dates. Based on the energy storage adjustment data of the controlled energy storage device within the remaining capacity range, determine the energy storage adjustment period data within the adaptation deviation range within the remaining capacity range; Based on the energy storage adjustment period data within the remaining capacity range and the adaptation deviation range, as well as the adaptation adjustment date data, the energy storage adjustment control strategy of the controlled energy storage device within the remaining capacity range is determined.

[0035] It is understandable that when the proportion of the number of adaptation adjustment dates in the most recent preset time period is greater than the preset proportion threshold, it indicates that there are a large number of energy storage adjustment periods in the adaptation deviation range. Therefore, a preset adjustment control strategy is adopted in different remaining capacity ranges to determine the energy storage adjustment control strategy of the energy storage device.

[0036] In one possible specific embodiment, the most recent preset time period is three months, and the preset percentage threshold is 0.1.

[0037] It should also be noted that when the proportion of the number of the adaptation adjustment dates is not greater than the preset proportion threshold, the energy storage adjustment period data within the adaptation deviation range in the most recent preset time period is determined. When the energy storage adjustment period data within the adaptation deviation range in the most recent preset time period meets the requirements, that is, when the number of energy storage adjustment periods within the adaptation deviation range in the most recent preset time period is large, the preset adjustment control strategy is adopted in different remaining capacity ranges to determine the energy storage adjustment control strategy of the energy storage device.

[0038] For example, if the number of energy storage adjustment periods within the adaptation deviation range is not less than 20 within the most recent preset time period, then the preset adjustment control strategy is adopted in different remaining capacity ranges, and the energy storage adjustment control strategy of the energy storage device is determined.

[0039] Furthermore, if the energy storage adjustment period data within the adaptation deviation interval does not meet the requirements in the most recent preset time period, then the energy storage adjustment period data within the adaptation deviation interval in the remaining capacity interval is determined. If the number of energy storage adjustment periods within the adaptation deviation interval in the remaining capacity interval is less than a preset time period number threshold, for example, less than 10, then the preset adjustment control strategy is adopted in the remaining capacity interval, and the energy storage adjustment control strategy for controlling the energy storage device is determined.

[0040] It should be noted that the remaining capacity range is divided into equal intervals of 10% for the remaining energy storage capacity of the distributed energy storage device, i.e., 10%, 20% up to 100%.

[0041] Additionally, it can be understood that if the number of energy storage adjustment periods within the adaptation deviation range in the remaining capacity range is not less than a preset threshold number of periods, then the adaptation deviation value is determined based on the remaining capacity range data using the preset adjustment control strategy, the proportion of the remaining capacity range using the preset adjustment control strategy, and the number of energy storage adjustment periods within the adaptation deviation range in the remaining capacity range. When the adaptation deviation value is less than the preset deviation threshold, for example, less than 0.6, then the preset adjustment control strategy is determined to be used within the remaining capacity range, and the energy storage adjustment control strategy for the energy storage device is determined.

[0042] In one possible embodiment, the distribution clustering value of the remaining capacity range is determined based on the ratio of the number of energy storage adjustment periods of the energy storage device within the remaining capacity range and within the adaptation deviation range to the average number of energy storage adjustment periods within the adaptation deviation range in different remaining capacity ranges. The adaptation deviation value is then determined based on the distribution clustering value and the average proportion of the remaining capacity ranges using the preset adjustment control strategy.

[0043] It can also be understood that when the adaptation deviation value within the remaining capacity range is not less than the preset deviation threshold, it is determined that a second preset regulation and control strategy is adopted within the remaining capacity range, and the energy storage regulation and control strategy of the energy storage device is determined.

[0044] It should be noted that the preset adjustment and control strategy is to control the output of other energy storage devices (excluding the control energy storage device) when different distribution areas have energy storage adjustment needs. This ensures that the energy storage adjustment needs of different distribution areas minus the energy storage adjustment power output of other energy storage devices is maintained within the adaptation deviation range. The control energy storage device is then used for energy storage adjustment processing. For example, if the maximum value of the endpoint of the adaptation deviation range is C, then if the sum of the energy storage adjustment power of the energy storage adjustment needs of different distribution areas is A, the energy storage adjustment power output of other energy storage devices (excluding the control energy storage device) is controlled to A minus C, thereby enabling the control energy storage device to operate within the adaptation deviation range.

[0045] Additionally, it can be understood that when the energy storage regulation demand corresponding to the energy storage regulation demand of any transformer area falls within the adaptation deviation range, the control energy storage device is controlled to perform energy storage regulation processing.

[0046] Specifically, the method for determining the coordinated regulation and processing strategy that does not belong to the control of energy storage devices is as follows: Based on the energy storage regulation and control strategy, determine the remaining capacity range of the energy storage device when the preset regulation and control strategy is adopted; The remaining capacity range of the control energy storage device is determined based on the remaining capacity range of the distributed energy storage device. Based on the energy storage regulation control strategy of the remaining capacity range where the controlled energy storage device is located, and the historical regulation data of the remaining capacity range where the controlled energy storage device is located within the adaptation deviation range, it is determined that when there is an energy storage regulation demand, the coordinated regulation processing strategy of the energy storage device that does not belong to the controlled energy storage device is determined.

[0047] When the remaining capacity range of the controlled energy storage device is within the remaining capacity range of the preset adjustment control strategy, if the number of energy storage adjustment periods within the adaptation deviation range of the remaining capacity range of the controlled energy storage device is less than the second preset threshold number of time periods, then the collaborative adjustment processing strategy for energy storage devices that do not belong to the controlled energy storage device is to ensure that, during energy storage adjustment, at least a first preset number of energy storage devices that do not belong to the controlled energy storage device can meet the energy storage adjustment power requirements of the adaptation deviation range.

[0048] Additionally, it can be understood that if the number of energy storage adjustment periods within the adaptation deviation range of the remaining capacity range where the controlled energy storage device is located is not less than the second preset time period threshold, and when the remaining capacity range adjacent to the remaining capacity range where the controlled energy storage device is located also belongs to the remaining capacity range using the preset adjustment control strategy, then the collaborative adjustment processing strategy for energy storage devices that do not belong to the controlled energy storage device is to ensure that, during energy storage adjustment, at least a first preset number of energy storage devices that do not belong to the controlled energy storage device can meet the energy storage adjustment power requirements of the adaptation deviation range.

[0049] It should be noted that the adjacent remaining capacity interval is a remaining capacity interval that overlaps with the endpoint of the remaining capacity interval where the controlled energy storage device is located. In a possible specific embodiment, the second preset time period number threshold is 5.

[0050] Furthermore, if the remaining capacity range adjacent to the remaining capacity range where the controlled energy storage device is located is also not a remaining capacity range for which a preset adjustment control strategy is adopted, then the collaborative adjustment processing strategy for energy storage devices that are not controlled energy storage devices is to ensure, during energy storage adjustment, at least a second preset number of energy storage devices that are not controlled energy storage devices can meet the energy storage adjustment power requirements of the adaptation deviation range.

[0051] Example 2 On the other hand, the present invention provides a computer system comprising: a memory and a processor connected in communication, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the above-described method for collaborative management and control of distributed energy storage devices in a power distribution network when running the computer program.

[0052] Furthermore, the method for determining the coordinated regulation and processing strategy that does not belong to the control of energy storage devices is as follows: Based on the energy storage regulation and control strategy, determine the remaining capacity range of the energy storage device when the preset regulation and control strategy is adopted; The remaining capacity range of the control energy storage device is determined based on the remaining capacity range of the distributed energy storage device. Based on the remaining capacity range of the energy storage device using the preset adjustment control strategy, and the historical adjustment data of the remaining capacity range of the energy storage device within the adaptation deviation range, it is determined that when there is an energy storage adjustment demand, the coordinated adjustment processing strategy of the energy storage device is not applicable to the energy storage device.

[0053] It should be noted that when the number of remaining capacity intervals of the energy storage device using the preset adjustment control strategy is greater than the interval number threshold, the collaborative adjustment processing strategy for energy storage devices that do not belong to the control energy storage device is to ensure that at least a first preset number of energy storage devices that do not belong to the control energy storage device can meet the energy storage adjustment power requirements of the adaptation deviation interval when performing energy storage adjustment. In other words, the energy storage adjustment power of the adaptation deviation interval can be adjusted by using the first preset number of energy storage devices that do not belong to the control energy storage device.

[0054] In one possible specific embodiment, when the number of remaining capacity ranges of the controlled energy storage device using the preset adjustment control strategy is not less than 4, at least 2 energy storage devices that do not belong to the controlled energy storage device are guaranteed to meet the energy storage adjustment power requirements of the adaptation deviation range. This allows the controlled energy storage device to use energy storage devices that do not belong to the controlled energy storage device for adjustment when the energy storage adjustment power does not meet the requirements during the energy storage adjustment process of the adaptation deviation range.

[0055] Furthermore, when the number of remaining capacity intervals of the controlled energy storage device using the preset adjustment control strategy is not greater than the interval number threshold, the energy storage adjustment power corresponding to the current energy storage adjustment demand is obtained, and the deviation between it and the endpoint of the adaptation deviation interval is obtained. When the deviation does not meet the requirements, that is, when the deviation between the energy storage adjustment power corresponding to the current energy storage adjustment demand and the minimum value of the endpoint of the adaptation deviation interval is small, for example, less than 5%, the collaborative adjustment processing strategy for energy storage devices that do not belong to the controlled energy storage device is to ensure that at least a first preset number of energy storage devices that do not belong to the controlled energy storage device can meet the energy storage adjustment power demand of the adaptation deviation interval during energy storage adjustment.

[0056] In one possible specific embodiment, if the ratio of the deviation between the energy storage regulation power corresponding to the current energy storage regulation demand and the minimum value of the endpoint of the adaptation deviation interval to the minimum value of the endpoint of the adaptation deviation interval is less than 5%, then the collaborative regulation processing strategy for energy storage devices that do not belong to the controlled energy storage devices is to ensure that, when performing energy storage regulation, at least a first preset number of energy storage devices that do not belong to the controlled energy storage devices can meet the energy storage regulation power demand of the adaptation deviation interval.

[0057] Additionally, it can be understood that when the deviation meets the requirements, it is determined whether the remaining capacity range where the controlled energy storage device is located belongs to the remaining capacity range using the preset adjustment control strategy. When the remaining capacity range where the controlled energy storage device is located does not belong to the remaining capacity range using the preset adjustment control strategy, the collaborative adjustment processing strategy for energy storage devices that do not belong to the controlled energy storage device is to ensure that, during energy storage adjustment, at least a second preset number of energy storage devices that do not belong to the controlled energy storage device can meet the energy storage adjustment power requirements of the adaptation deviation range.

[0058] In one possible specific embodiment, the second preset quantity is 3.

[0059] Furthermore, when the remaining capacity range of the controlled energy storage device belongs to the remaining capacity range using a preset adjustment control strategy, if the number of energy storage adjustment periods within the adaptation deviation range of the remaining capacity range of the controlled energy storage device is less than a second preset threshold number of time periods, then the collaborative adjustment processing strategy for energy storage devices that do not belong to the controlled energy storage device is to ensure that, during energy storage adjustment, at least a first preset number of energy storage devices that do not belong to the controlled energy storage device can meet the energy storage adjustment power requirements of the adaptation deviation range.

[0060] Additionally, it can be understood that if the number of energy storage adjustment periods within the adaptation deviation range of the remaining capacity range where the controlled energy storage device is located is not less than the second preset time period threshold, and when the remaining capacity range adjacent to the remaining capacity range where the controlled energy storage device is located also belongs to the remaining capacity range using the preset adjustment control strategy, then the collaborative adjustment processing strategy for energy storage devices that do not belong to the controlled energy storage device is to ensure that, during energy storage adjustment, at least a first preset number of energy storage devices that do not belong to the controlled energy storage device can meet the energy storage adjustment power requirements of the adaptation deviation range.

[0061] It should be noted that the adjacent remaining capacity interval is a remaining capacity interval that overlaps with the endpoint of the remaining capacity interval where the controlled energy storage device is located. In a possible specific embodiment, the second preset time period number threshold is 5.

[0062] Furthermore, if the remaining capacity range adjacent to the remaining capacity range where the controlled energy storage device is located is also not a remaining capacity range for which a preset adjustment control strategy is adopted, then the collaborative adjustment processing strategy for energy storage devices that are not controlled energy storage devices is to ensure, during energy storage adjustment, at least a second preset number of energy storage devices that are not controlled energy storage devices can meet the energy storage adjustment power requirements of the adaptation deviation range.
