[0005] To achieve the purpose of the present application, the present application adopts the following technical solutions:

[0006] According to one aspect of the present application, a distributed energy storage device collaborative management method for a power distribution network is provided.

Based on the energy storage regulation data in the adaptation deviation interval, the control energy storage devices in the distributed energy storage devices are determined.

[0009] According to the energy storage adjustment period data in the adaptive deviation interval and the energy storage adjustment data of the control energy storage device in different residual capacity intervals, the energy storage adjustment control strategy of the control energy storage device in different residual capacity intervals is determined, and the collaborative adjustment processing strategy of the control energy storage device is determined based on the energy storage adjustment processing demand and the residual capacity interval of the distributed energy storage device, with the energy storage adjustment control strategy and the adaptive deviation interval as constraint conditions.

[0010] The present application has the following advantages:

[0011] According to the energy storage adjustment period data in the adaptive deviation interval and the energy storage adjustment data of the control energy storage device in different residual capacity intervals, the energy storage adjustment control strategy of the control energy storage device in different residual capacity intervals is determined, so as to consider the number of energy storage adjustments of the control energy storage device in the residual capacity interval, realize the evaluation of the reliability of the verification processing result of the adjustment reliability of the control energy storage device in the residual capacity interval, and further combine the energy storage adjustment period data in the adaptive deviation interval, also consider the energy storage adjustment demand corresponding to the adaptive deviation interval, and then realize the determination of the energy storage adjustment control strategy in different residual capacity intervals from the energy storage adjustment demand and the reliability of the verification processing result, and guarantee the reliability of the verification processing of the control energy storage device in different residual capacity intervals.

[0030] 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.

[0031] 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.

[0032] Example 1

[0033] 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:

[0034] 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.

[0035] 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.

[0036] Further, the energy storage adjustment power interval is equally divided according to a preset power, and in a possible embodiment, the preset power is 20 KW.

[0037] Specifically, as shown in Figure 2 the method for determining the adaptive deviation interval in the energy storage adjustment power interval is:

[0038] Based on the adaptive condition of the distributed energy storage device in the power distribution network in each energy storage adjustment power interval, energy storage adjustment data of the distributed energy storage device in the energy storage adjustment power interval is determined.

[0039] Based on the energy storage adjustment data, the adaptive distributed energy storage device in the energy storage adjustment power interval is determined.

[0040] Based on the distribution data of the adaptive distributed energy storage device in the energy storage adjustment power interval, it is determined whether the energy storage adjustment power interval is an adaptive deviation interval.

[0041] It should be noted that the adaptive distributed energy storage device in the energy storage adjustment power interval is the distributed energy storage device whose energy storage adjustment power falls within the rated energy storage adjustment power.

[0042] It should be noted that when the number of adaptive distributed energy storage devices in the energy storage adjustment power interval meets the requirements and the line loss data between different power distribution areas meets the requirements, it is determined that the energy storage adjustment power interval does not belong to the adaptive deviation interval.

[0043] In a possible specific embodiment, if the line loss rate of the adaptive distributed energy storage device in different power distribution areas is less than 10% and the number of distributed energy storage devices is not less than 3, it is determined that the energy storage adjustment power interval does not belong to the adaptive deviation interval.

[0044] Optionally, the method for determining the adaptive deviation interval in the energy storage adjustment power interval is:

[0045] Based on the adaptive condition of the distributed energy storage device in the power distribution network in each energy storage adjustment power interval, energy storage adjustment data of the distributed energy storage device in the energy storage adjustment power interval is determined.

[0046] Based on the energy storage adjustment data, the adaptive distributed energy storage device in the energy storage adjustment power interval is determined.

[0047] Based on the distribution data of the adaptive distributed energy storage device in the energy storage adjustment power interval, it is determined whether the energy storage adjustment power interval is an adaptive deviation interval.

[0048] Specifically, when the number of the adaptive distributed energy storage devices in the energy storage regulation power interval is less than the preset energy storage device number threshold, for example, is not more than 2, since the number of the adaptive distributed energy storage devices in the energy storage regulation power interval is less, it is determined that the energy storage regulation power interval is an adaptive deviation interval.

[0049] Specifically, as shown in Figure 3 The method for determining the control energy storage device in the distributed energy storage device is:

[0050] Based on the energy storage regulation data in the adaptive deviation interval, the energy storage regulation period data of the adaptive distributed energy storage device in the adaptive deviation interval is determined;

[0051] Based on the energy storage regulation period data, the energy storage regulation period data of the adaptive distributed energy storage device in the adaptive deviation interval in different remaining capacity intervals is determined;

[0052] The control energy storage device in the distributed energy storage device is determined by using the energy storage regulation period data of the adaptive distributed energy storage device in the adaptive deviation interval in different remaining capacity intervals.

[0053] It should be noted that when there is only one adaptive distributed energy storage device in the adaptive deviation interval, it is determined that the adaptive distributed energy storage device in the adaptive deviation interval belongs to the control energy storage device;

[0054] In addition, it can be understood that when there is not only one adaptive distributed energy storage device in the adaptive deviation interval, based on the energy storage regulation period data of the adaptive distributed energy storage device in the adaptive deviation interval in different remaining capacity intervals, the adaptive distributed energy storage device in the adaptive deviation interval with the least number of remaining capacity intervals in the preset number interval is taken as the control energy storage device, for example, the adaptive distributed energy storage device in the adaptive deviation interval with the least number of remaining capacity intervals with less than 10 energy storage regulation periods is taken as the control energy storage device.

[0055] According to the energy storage regulation period data in the adaptive deviation interval and the energy storage regulation data of the control energy storage device in different remaining capacity intervals, the energy storage regulation control strategy of the control energy storage device in different remaining capacity intervals is determined, and based on the energy storage regulation processing demand and the remaining capacity interval of the distributed energy storage device, the collaborative regulation processing strategy of the energy storage device not belonging to the control energy storage device is determined as the constraint condition.

[0056] Optionally, the method for determining the energy storage regulation control strategy of the control energy storage device in different remaining capacity intervals is:

[0057] determine distribution data of the energy storage adjustment time period in the adaptation deviation interval in different dates based on the energy storage adjustment time period data in the adaptation deviation interval, determine dates in which the energy storage adjustment time period exists in the adaptation deviation interval based on the distribution data, and take the dates as the adaptation adjustment dates;

[0058] determine the energy storage adjustment time period data in the adaptation deviation interval in the residual capacity interval based on the energy storage adjustment data of the control energy storage device in the residual capacity interval;

[0059] determine a distribution aggregation value based on the energy storage adjustment time period data in the adaptation deviation interval in the residual capacity interval, and determine the energy storage adjustment control strategy of the control energy storage device in the residual capacity interval based on the distribution aggregation value and the adaptation adjustment date data.

[0060] It can be understood that when the proportion of the number of the adaptation adjustment dates in the most recent preset time period is greater than a preset proportion threshold, it indicates that the number of the energy storage adjustment time period in the adaptation deviation interval is large, and therefore a preset adjustment control strategy is used in different residual capacity intervals to determine the energy storage adjustment control strategy of the control energy storage device.

[0061] In addition, it can be understood that when the proportion of the number of the adaptation adjustment dates in the most recent preset time period is not greater than the preset proportion threshold, and when the distribution aggregation value is less than a preset aggregation threshold, for example, less than 0.6, a preset adjustment control strategy is used in the residual capacity interval to determine the energy storage adjustment control strategy of the control energy storage device.

[0062] Further, when the distribution aggregation value is not less than the preset aggregation threshold, a second preset adjustment control strategy is used in the residual capacity interval to determine the energy storage adjustment control strategy of the control energy storage device.

[0063] Further, the method for determining the energy storage adjustment control strategy of the control energy storage device in different residual capacity intervals is as follows:

[0064] determine distribution data of the energy storage adjustment time period in the adaptation deviation interval in different dates based on the energy storage adjustment time period data in the adaptation deviation interval, determine dates in which the energy storage adjustment time period exists in the adaptation deviation interval based on the distribution data, and take the dates as the adaptation adjustment dates;

[0065] determine the energy storage adjustment time period data in the adaptation deviation interval in the residual capacity interval based on the energy storage adjustment data of the control energy storage device in the residual capacity interval;

[0066] According to the energy storage adjustment time period data in the adaptation deviation interval and the adaptation adjustment date data in the remaining capacity interval, the energy storage adjustment control strategy of the control energy storage device in the remaining capacity interval is determined.

[0067] It can be understood that when the proportion of the number of adaptation adjustment dates in the recent preset time period is greater than the preset proportion threshold, it means that the number of energy storage adjustment time periods in the adaptation deviation interval is relatively large at this time, and therefore the preset adjustment control strategy is adopted in different remaining capacity intervals to determine the energy storage adjustment control strategy of the control energy storage device.

[0068] In a possible specific embodiment, the recent preset time period is three months, and the preset proportion threshold is 0.1.

[0069] In addition, it should be noted that when the proportion of the number of adaptation adjustment dates is not greater than the preset proportion threshold, the energy storage adjustment time period data in the adaptation deviation interval in the recent preset time period is determined, and when the energy storage adjustment time period data in the adaptation deviation interval in the recent preset time period meets the requirement, that is, the number of energy storage adjustment time periods in the adaptation deviation interval in the recent preset time period is relatively large, the preset adjustment control strategy is adopted in different remaining capacity intervals to determine the energy storage adjustment control strategy of the control energy storage device.

[0070] For example, when the number of energy storage adjustment time periods in the adaptation deviation interval in the recent preset time period is not less than 20, the preset adjustment control strategy is adopted in different remaining capacity intervals to determine the energy storage adjustment control strategy of the control energy storage device.

[0071] Further, if the energy storage adjustment time period data in the adaptation deviation interval in the recent preset time period does not meet the requirement, the energy storage adjustment time period data in the adaptation deviation interval in the remaining capacity interval is determined, and if the number of energy storage adjustment time periods in the adaptation deviation interval in the remaining capacity interval is less than a preset time period number threshold, for example, less than 10, the preset adjustment control strategy is adopted in the remaining capacity interval to determine the energy storage adjustment control strategy of the control energy storage device.

[0072] It should be noted that the remaining capacity interval is equally divided by 10% to perform the equal-interval division of the remaining energy storage capacity of the distributed energy storage device, that is, 10%, 20%, and so on to 100%.

[0073] In addition, it can be understood that if the number of energy storage adjustment periods in the adaptation deviation interval in the residual capacity interval is not less than the preset period threshold, then the residual capacity interval data using the preset adjustment control strategy is used as the basis to determine the adaptation deviation value based on the number of residual capacity intervals using the preset adjustment control strategy and the number of energy storage adjustment periods in the adaptation deviation interval in the residual capacity interval. When the adaptation deviation value is less than the preset deviation threshold, for example, less than 0.6, it is determined that the preset adjustment control strategy is used in the residual capacity interval, and the energy storage adjustment control strategy of the control energy storage device is determined.

[0074] In one possible embodiment, the distribution aggregation value of the residual capacity interval is determined based on the ratio of the number of energy storage adjustment periods in the adaptation deviation interval in the residual capacity interval to the average of the number of energy storage adjustment periods in the adaptation deviation interval in different residual capacity intervals. The adaptation deviation value is determined based on the average of the distribution aggregation value and the number of residual capacity intervals using the preset adjustment control strategy.

[0075] In addition, it can be understood that when the adaptation deviation value in the residual capacity interval is not less than the preset deviation threshold, the second preset adjustment control strategy is used in the residual capacity interval, and the energy storage adjustment control strategy of the control energy storage device is determined.

[0076] It should be noted that the preset adjustment control strategy is to control the output of other energy storage devices except the control energy storage device when there is an energy storage adjustment demand in different transformer areas, so that the energy storage adjustment demand in different transformer areas is maintained in the adaptation deviation interval after subtracting the energy storage adjustment power of the output of other energy storage devices except the control energy storage device, and the control energy storage device is used for energy storage adjustment processing. For example, if the maximum value of the end point of the adaptation deviation interval is C, and the sum of the energy storage adjustment power of the energy storage adjustment demand in different transformer areas is A, the output of other energy storage devices except the control energy storage device is controlled to A minus C, so that the control energy storage device can operate in the adaptation deviation interval.

[0077] In addition, it can be understood that when the energy storage adjustment demand power corresponding to the energy storage adjustment demand of any one transformer area falls within the adaptation deviation interval, the control energy storage device is controlled to perform energy storage adjustment processing.

[0078] Specifically, the method for determining the cooperative adjustment processing strategy that does not belong to the control energy storage device includes:

[0079] determine, based on the residual capacity interval of the control energy storage device, a residual capacity interval of the control energy storage device;

[0080] determine, based on the residual capacity interval of the control energy storage device, a residual capacity interval of the control energy storage device;

[0081] determine, based on the residual capacity interval of the control energy storage device, a residual capacity interval of the control energy storage device;

[0082] When the residual capacity interval of the control energy storage device belongs to the residual capacity interval adopting the preset adjustment control strategy, if the number of energy storage adjustment time intervals within the adaptive deviation interval of the residual capacity interval of the control energy storage device is less than the second preset time interval threshold, the cooperative adjustment processing strategy of the energy storage devices other than the control energy storage device is to ensure that at least a first preset number of energy storage devices other than the control energy storage device can meet the demand for energy storage adjustment power of the adaptive deviation interval when performing energy storage adjustment.

[0083] In addition, it can be understood that if the number of energy storage adjustment time intervals within the adaptive deviation interval of the residual capacity interval of the control energy storage device is not less than the second preset time interval threshold, when the adjacent residual capacity interval of the residual capacity interval of the control energy storage device also belongs to the residual capacity interval adopting the preset adjustment control strategy, the cooperative adjustment processing strategy of the energy storage devices other than the control energy storage device is to ensure that at least a first preset number of energy storage devices other than the control energy storage device can meet the demand for energy storage adjustment power of the adaptive deviation interval when performing energy storage adjustment.

[0084] It should be noted that the adjacent residual capacity interval is a residual capacity interval that overlaps with the end point of the residual capacity interval of the control energy storage device, and in a possible specific embodiment, the second preset time interval threshold is 5.

[0085] Further, if the adjacent residual capacity interval of the residual capacity interval of the control energy storage device also does not belong to the residual capacity interval adopting the preset adjustment control strategy, the cooperative adjustment processing strategy of the energy storage devices other than the control energy storage device is to ensure that at least a second preset number of energy storage devices other than the control energy storage device can meet the demand for energy storage adjustment power of the adaptive deviation interval when performing energy storage adjustment.

[0086] Embodiment 2

[0087] In another aspect, the present application provides a computer system, comprising a memory and a processor connected in communication, and a computer program stored on the memory and capable of running on the processor, wherein the processor executes the computer program to implement the above-mentioned method for collaborative management of distributed energy storage devices in a power distribution network.

[0088] Further, the method for determining the collaborative adjustment processing strategy of the energy storage devices other than the control energy storage device is:

[0089] Based on the energy storage adjustment control strategy, the remaining capacity interval of the control energy storage device using the preset adjustment control strategy is determined.

[0090] Based on the remaining capacity interval of the distributed energy storage device, the remaining capacity interval in which the control energy storage device is located is determined.

[0091] Based on the remaining capacity interval of the control energy storage device using the preset adjustment control strategy and the historical adjustment data of the remaining capacity interval in which the control energy storage device is located within the adaptive deviation interval, the collaborative adjustment processing strategy of the energy storage devices other than the control energy storage device is determined when there is an energy storage adjustment demand.

[0092] It should be noted that when the number of the remaining capacity intervals of the control energy storage device using the preset adjustment control strategy is greater than the interval number threshold, the collaborative adjustment processing strategy of the energy storage devices other than the control energy storage device is to ensure that at least a first preset number of energy storage devices other than the control energy storage device can meet the demand for energy storage adjustment power in the adaptive deviation interval when performing energy storage adjustment, that is, the first preset number of energy storage devices other than the control energy storage device can be used to adjust the energy storage adjustment power in the adaptive deviation interval.

[0093] In one possible embodiment, when the number of the remaining capacity intervals of the control energy storage device using the preset adjustment control strategy is not less than 4, at least 2 energy storage devices other than the control energy storage device can meet the demand for energy storage adjustment power in the adaptive deviation interval, so that the control energy storage device can use the energy storage devices other than the control energy storage device to perform adjustment processing when the energy storage adjustment power does not meet the requirement.

[0094] Further, when the number of the remaining capacity intervals adopting the preset adjustment control strategy of the control energy storage device is not greater than the interval number threshold, the deviation of the current energy storage adjustment power corresponding to the current energy storage adjustment demand from the end point of the adaptive deviation interval is obtained. When the deviation does not meet the requirement, that is, the deviation of the current energy storage adjustment power corresponding to the current energy storage adjustment demand from the minimum value of the end point of the adaptive deviation interval is small, for example, less than 5%, the cooperative adjustment processing strategy of the energy storage devices other than the control energy storage device is that at least the first preset number of energy storage devices other than the control energy storage device can meet the demand of the energy storage adjustment power of the adaptive deviation interval when performing energy storage adjustment.

[0095] In a possible specific embodiment, when the ratio of the deviation of the current energy storage adjustment power corresponding to the current energy storage adjustment demand from the minimum value of the end point of the adaptive deviation interval to the minimum value of the end point of the adaptive deviation interval is less than 5%, the cooperative adjustment processing strategy of the energy storage devices other than the control energy storage device is that at least the first preset number of energy storage devices other than the control energy storage device can meet the demand of the energy storage adjustment power of the adaptive deviation interval when performing energy storage adjustment.

[0096] In addition, it can be understood that when the deviation meets the requirement, it is determined whether the remaining capacity interval in which the control energy storage device is located belongs to the remaining capacity interval adopting the preset adjustment control strategy. When the remaining capacity interval in which the control energy storage device is located does not belong to the remaining capacity interval adopting the preset adjustment control strategy, the cooperative adjustment processing strategy of the energy storage devices other than the control energy storage device is that at least the second preset number of energy storage devices other than the control energy storage device can meet the demand of the energy storage adjustment power of the adaptive deviation interval when performing energy storage adjustment.

[0097] In a possible specific embodiment, the second preset number is 3.

[0098] Further, when the remaining capacity interval in which the control energy storage device is located belongs to the remaining capacity interval adopting the preset adjustment control strategy, and when the number of the energy storage adjustment time intervals of the control energy storage device in the adaptive deviation interval is less than the second preset time interval threshold, the cooperative adjustment processing strategy of the energy storage devices other than the control energy storage device is that at least the first preset number of energy storage devices other than the control energy storage device can meet the demand of the energy storage adjustment power of the adaptive deviation interval when performing energy storage adjustment.

[0099] In addition, it can be understood that if the number of the energy storage adjustment time periods in the adaptation deviation interval is not less than the second preset time period number threshold when the control energy storage device is in the remaining capacity interval, and the adjacent remaining capacity interval of the control energy storage device also belongs to the remaining capacity interval adopting the preset adjustment control strategy, then the cooperative adjustment processing strategy of the energy storage devices other than the control energy storage device is that at least the first preset number of energy storage devices other than the control energy storage device can meet the demand of the energy storage adjustment power of the adaptation deviation interval when the energy storage adjustment is performed.

[0100] It should be noted that the adjacent remaining capacity interval is the remaining capacity interval that has an overlap with the end point of the remaining capacity interval in which the control energy storage device is located, and in a possible specific embodiment, the second preset time period number threshold is 5.

[0101] Further, if the adjacent remaining capacity interval of the control energy storage device also does not belong to the remaining capacity interval adopting the preset adjustment control strategy, then the cooperative adjustment processing strategy of the energy storage devices other than the control energy storage device is that at least the second preset number of energy storage devices other than the control energy storage device can meet the demand of the energy storage adjustment power of the adaptation deviation interval when the energy storage adjustment is performed.

Each of the embodiments mainly describes the difference from other embodiments. In particular, for the device, equipment, and nonvolatile computer storage medium embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the part of the method embodiments.
