[0038] Embodiment 1

[0039] Figure 1 It is a flowchart of a method for controlling an energy storage device provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of controlling an energy storage device and is used to control the power system to reach a state of supply-demand balance. This method can be executed by an energy storage device control device, which can be implemented in the form of hardware and / or software. The energy storage device control device can be configured in the edge computing module corresponding to the energy storage device in the energy storage device cluster, or can also be configured in a server and the electronic device provided in the embodiment.

[0040] In this embodiment, the target power system includes, but is not limited to, power generation side devices, energy storage side devices, and load side devices. The power generation side devices can be devices for generating new energy power resources, including but not limited to wind power generation devices, photovoltaic power generation devices, and tidal power generation devices. The power generation side devices transmit power resources to the energy storage side devices and the load side devices. The energy storage side devices are used to receive the power resources transmitted by the power generation side devices and transmit power resources to the load side devices. The load side devices are used to receive the power resources transmitted by the power generation side devices and the energy storage side devices. In order to optimize the computing power allocation, corresponding edge computing modules are set at each power generation side device, each energy storage side device, and each load side device. Specifically, the corresponding edge computing modules are set according to the computing power requirements corresponding to each power generation side device, each energy storage side device, and each load side device. By allocating the corresponding computing power on demand, the optimization of the new energy power grid calculation and the control of the computing power cost are realized. The method for controlling an energy storage device in this embodiment is applied to the edge computing module corresponding to the energy storage device in the energy storage device cluster. The energy storage device cluster includes multiple energy storage devices, and an edge computing module is set at each energy storage device.

[0041] As Figure 1 shown, the method includes:

[0042] S110. Obtain the power supply and demand status of the target power system, where the power supply and demand status includes any one of power balance, power surplus, and power deficit.

[0043] Among them, the target power system refers to the power system that needs to perform power balance control. The target power system includes, but is not limited to, power generation side equipment, energy storage side equipment, and load side equipment. The power supply and demand status specifically represents the balance status of the power resources provided by the power system and the power resources required by the load side. In this embodiment, it can be understood as the balance status of the power resources provided by the power generation side equipment and the power resources required by the load side equipment. The power supply and demand status includes any one of power balance, power surplus, and power deficit. Power balance represents that the power resources provided by the power generation side and the power resources required by the load side are in a balanced state. Power surplus represents the state where the power resources provided by the power generation side are more than the power resources required by the load side. Power deficit represents the state where the power resources provided by the power generation side are less than the power resources required by the load side. The power supply and demand status can be obtained in real time from the cloud server corresponding to the target power system, or the power supply and demand status sent by the cloud server can be received regularly.

[0044] Specifically, if it is necessary to grasp the power supply and demand status of the power system in real time, then the power supply and demand status of the target power system can be obtained in real time from the corresponding cloud server. Among them, the power supply and demand status includes any one of power balance, power surplus, and power deficit. Determine the control strategy for the energy storage device under different supply and demand statuses to control the power system to be in a supply and demand balance state. It should be noted that in the case of power balance in the power supply and demand status, no processing may be performed, and the operating state of the power system may be maintained. Among them, the control strategy includes the energy storage device combination selected from the energy storage device cluster, and the energy storage device combination includes at least one energy storage device.

[0045] In this embodiment, by obtaining the power supply and demand status of the target power system, it is helpful to determine the control strategy of the energy storage device in a timely manner according to the power supply and demand status, so as to ensure that the target power system is in a power balance state, which is helpful to improve the stability of the operation of the power system.

[0046] S120. In the case of power surplus in the power supply and demand status, determine at least one first energy storage device from the energy storage device cluster based on the power surplus of the target power system and the current energy storage information of each energy storage device in the energy storage device cluster, and control at least one first energy storage device to store the surplus power resources.

[0047] Among them, the power surplus represents the amount of power resources provided by the power generation side that exceeds the power resources required by the load side, that is, the amount of power resources used for storage processing. The energy storage device cluster includes multiple energy storage devices, which are used to meet the power storage requirements of the power system and the demand for providing the missing power resources to the load side. The energy storage information represents the energy storage parameters related to the energy storage devices. The energy storage information includes, but is not limited to, the stored energy and the storage capacity. The stored energy represents the actual storage amount in the energy storage device, and the storage capacity represents the rated storage amount of the energy storage device. To select an energy storage device from the energy storage device cluster for storing surplus power resources, at least one energy storage device can be randomly selected from the energy storage device cluster. If it is determined based on the current energy storage information of the selected energy storage device that the selected energy storage device cannot meet the storage demand for the power resources of the power surplus size, then additional energy storage devices need to be selected until the multiple selected energy storage devices can meet the storage demand for the power resources of the power surplus size; alternatively, the corresponding priorities can be determined according to the current energy storage information of each energy storage device, and the energy storage devices can be selected in sequence according to the priorities until the selected energy storage devices can meet the storage demand for the power resources of the power surplus size. Preferably, the available storage space size can be determined according to the current energy storage information of each energy storage device, and the energy storage devices can be sorted in descending order according to the available storage space size. The priorities of the corresponding energy storage devices can be set according to the sorting results, and the energy storage devices can be selected in sequence according to the priorities until the storage space of at least one selected energy storage device can meet the storage demand for the power resources of the power surplus size; alternatively, the power surplus can be evenly distributed, and each energy storage device in the energy storage device cluster can evenly bear the demand for storing power resources. The first energy storage device can be understood as the energy storage device used to represent the storage processing of power resources, specifically to distinguish it from the energy storage device used for power resource release processing.

[0048] Specifically, when the edge computing module corresponding to the energy storage side device identifies the received power supply and demand status and determines that the power supply and demand status is power surplus, the power surplus of the target power system can be obtained. Using the power surplus as the screening constraint condition, energy storage devices that can match the power surplus are selected from the energy storage device cluster. If it is determined based on the current energy storage information of any randomly selected energy storage device that none of the energy storage devices can meet the storage requirements corresponding to the power surplus, then two energy storage devices are selected. If the two energy storage devices still cannot meet the storage requirements corresponding to the power surplus, the selection continues until multiple selected energy storage devices can meet the storage requirements corresponding to the power surplus, thereby obtaining at least one first energy storage device that meets the storage requirements corresponding to the power surplus for storing surplus power resources. Among them, the selection of energy storage devices can be random or can be made according to the priority of the energy storage devices. When at least one energy storage device is determined, control at least one first energy storage device to store surplus power resources so that the power supply and demand status of the power system tends to a balanced state.

[0049] In this embodiment, when it is identified that the power supply and demand status is power surplus, using the power surplus of the target power system as the constraint condition, energy storage devices are selected from the energy storage device cluster according to the current energy storage information of each energy storage device in the energy storage device cluster to complete the storage of surplus power resources. This realizes the matching of energy storage devices that meet the power surplus according to the current energy storage information of the energy storage devices, avoids waste of power resources, can carry the storage requirements of the power surplus according to the current energy storage information of the energy storage devices, improves the utilization rate of the energy storage devices, and also avoids waste of storage resources.

[0050] S130. When the power supply and demand status is power deficit, based on the power deficit amount of the target power system and the current energy storage information of each energy storage device in the energy storage device cluster, determine at least one second energy storage device from the energy storage device cluster, and control at least one second energy storage device to release power resources based on the power deficit amount.

[0051] Among them, the power deficit represents the amount of power resources lacking in the power resources provided by the power generation side compared to those required by the load side, that is, the amount of power resources that the energy storage device needs to release. Selecting energy storage devices for power resource release from the energy storage device cluster, with the power deficit as the constraint condition, it is possible to match according to the current energy storage information of each energy storage device in the energy storage device cluster and the power deficit. One energy storage device can be randomly selected from the successfully matched energy storage devices for power resource release. In the case where a single energy storage device that can meet the power deficit is not found, two energy storage devices are selected for resource release. If the two energy storage devices still do not meet the power deficit, more energy storage devices are continuously selected until the amount of power resources that the selected energy storage devices can provide matches the power deficit. Among them, the determination condition for successful matching can be set such that the total amount of releasable power resources corresponding to the energy storage information of the selected energy storage devices meets the power deficit; it is also possible to sort the energy storage devices in descending order according to the actual stored energy corresponding to the current energy storage information of each energy storage device in the energy storage device cluster, set the priority of each energy storage device according to the sorting result, and select the energy storage devices in sequence. When the total amount of releasable power resources corresponding to the energy storage information of the selected energy storage devices meets the power deficit, the selection stops, and at least one second energy storage device for power resource release is obtained for power resource release. The second energy storage device can be understood as an energy storage device used to represent the processing of power resource release, specifically distinguished from the energy storage device used for power resource storage processing.

[0052] Specifically, after identifying the received power supply and demand status, when it is identified that the power supply and demand status is a power deficit, obtain the power deficit amount of the target power system. Using the power deficit amount as the screening constraint condition, select energy storage devices from the energy storage device cluster that can match the power deficit amount. If the current energy storage information of any one energy storage device does not match the power deficit amount, select two energy storage devices. If the current energy storage information of the two energy storage devices does not match the power deficit amount, continue to select until the sum of the energy storage information of the selected multiple energy storage devices can match the power deficit amount, thereby obtaining at least one second energy storage device for releasing power resources to compensate for the missing power resources on the load side, so as to control the power system to be in a power balance state. Among them, the selection of energy storage devices can be carried out according to a pre-set selection rule. The selection rule includes a selection method and a constraint condition. Among them, the selection method can be random selection or selection according to the priority of the energy storage device. The priority of the energy storage device can be determined according to the current energy storage information of the energy storage device. Preferably, it can be sorted in descending order according to the energy storage value corresponding to the current energy storage information, and the descending order result is used as the priority of the corresponding energy storage device. The constraint condition can be that the sum of the energy storage information of the selected multiple energy storage devices can meet the power deficit amount, and the number of the selected multiple energy storage devices is the least. When determining at least one second energy storage device, control at least one second energy storage device to release power resources based on the power deficit amount, so that the supply and demand status of the power system tends to a balanced state.

[0053] In this embodiment, when it is identified that the power supply and demand status is a power deficit, set the constraint condition with the power deficit amount of the target power system, and select energy storage devices from the energy storage device cluster according to the current energy storage information of each energy storage device in the energy storage device cluster to compensate for the missing power resources on the load side. It realizes matching the energy storage devices that meet the power deficit amount according to the current energy storage information of the energy storage devices, avoids waste of resources, can carry the power resource demand of the power deficit amount according to the current energy storage information of the energy storage devices, improves the utilization rate of the energy storage devices, helps to improve the rapidity of the power system to reach the power balance state, and ensures the stable operation of the power system.

[0054] On the basis of the above embodiments, information sharing is performed among the edge computing modules respectively corresponding to each energy storage device; after determining at least one first energy storage device or at least one second energy storage device, the method further includes: traversing the at least one first energy storage device or the at least one second energy storage device determined by each edge computing module to obtain the device numbers in the at least one first energy storage device or the device numbers in the at least one second energy storage device; classifying and counting the at least one first energy storage device or the at least one second energy storage device according to the device numbers, and determining the weight information corresponding to the at least one first energy storage device or the at least one second energy storage device determined by each edge computing module according to the statistical result; obtaining the usage times corresponding to each energy storage device in the energy storage device cluster, and adjusting the at least one first energy storage device or the at least one second energy storage device based on the weight information and / or the usage times.

[0055] Wherein, each energy storage device in the energy storage device cluster is provided with a device number, and the device numbers of the energy storage devices in the same energy storage device cluster are unique. Specifically, information sharing is performed among the edge computing modules respectively corresponding to each energy storage device.

[0056] After determining at least one first energy storage device or at least one second energy storage device, obtain the at least one first energy storage device or at least one second energy storage device determined by each edge computing module. For the at least one first energy storage device determined by each edge computing module, the at least one first energy storage device determined by each edge computing module can be used as a first energy storage device set. Traverse the first energy storage device sets determined by each edge computing module, classify and count the first energy storage device sets, count the first energy storage device sets with the same label information, and set the statistical result as the weight data of the corresponding first energy storage device set. It can be understood that the larger the number of sets of the first energy storage device set with the same device number information, the greater the weight value of the corresponding first energy storage device set. The first energy storage device set with the largest weight value can be used as the target energy storage device set to control each energy storage device in the target energy storage device set to store surplus power resources. Alternatively, obtain the usage times corresponding to each energy storage device in the energy storage device cluster, determine the usage times of the energy storage devices in each first energy storage device set and the usage times of the energy storage devices outside the set, match the energy storage devices in each first energy storage device set with the energy storage devices outside the set. If the matching condition is met, the energy storage device outside the set that matches successfully will replace the energy storage device inside the set to obtain the updated first energy storage device, where the matching condition includes that the error between the current energy storage information of the energy storage device outside the set and the current energy storage information of the energy storage device inside the set is within a preset range, and the usage times of the energy storage device outside the set are less than the usage times of the energy storage device inside the set, so as to ensure that the goal of storing surplus power resources can be achieved while avoiding the problem of excessive usage times of individual energy storage devices, which helps to balance the utilization rate of energy storage devices and improve the service life of energy storage devices. Alternatively, the energy storage devices in the first energy storage device sets determined by each edge computing module can be adjusted according to the usage times corresponding to the energy storage devices first, and then, the adjusted first energy storage device sets are classified and counted to determine the weight data of each first energy storage device set, so as to determine the target first energy storage device set according to the weight data. The energy storage devices in the initially determined at least one first energy storage device can be adjusted according to any of the above methods.

[0057] Accordingly, for at least one second energy storage device determined by each edge computing module, traverse the at least one second energy storage device determined by each edge computing module to obtain the device numbers in the at least one second energy storage device; classify and count the at least one second energy storage device according to the device numbers, and determine the weight information corresponding to the at least one second energy storage device determined by each edge computing module according to the statistical results; obtain the usage times corresponding to each energy storage device in the energy storage device cluster, and adjust the at least one second energy storage device based on the weight information and / or the usage times. The specific process of adjusting the at least one second energy storage device based on the weight information and / or the usage times can refer to the adjustment process of adjusting the at least one first energy storage device, which will not be elaborated here.

[0058] In this embodiment, information sharing is carried out between the edge computing modules respectively corresponding to each energy storage device. Each edge computing module determines at least one first energy storage device or at least one energy storage device according to the shared information, determines the weight information corresponding to the at least one first energy storage device or at least one energy storage device, and adjusts the at least one first energy storage device or at least one second energy storage device based on the weight information and / or the usage times, achieving the situation of being able to store the power resources corresponding to the power surplus while avoiding the problem of excessive usage times of individual energy storage devices, and being able to provide power resources to meet the power deficit for the load side while avoiding the problem of excessive usage times of individual energy storage devices. While improving the control efficiency of power balance in the power system, it also improves the service life of the energy storage devices.

As Figure 2 shown, the method includes:

[0062] S210. Obtain the power supply and demand status of the target power system, where the power supply and demand status includes any one of power balance, power surplus, and power deficit.

[0063] S220. When the power supply and demand state is power surplus, obtain the current energy storage information corresponding to each energy storage device in the energy storage device cluster, and determine the idle energy storage information of the energy storage device based on the current energy storage information of the energy storage device.

[0064] Among them, the idle energy storage information can be specifically understood as the information used to characterize the remaining energy storage space of the energy storage device, which can be the capacity size or percentage information of the remaining energy storage space.

[0065] Specifically, when the power supply and demand state is power surplus, obtain the current energy storage information corresponding to each energy storage device in the energy storage device cluster. The current energy storage information includes the actual stored energy and the rated stored energy of the energy storage device. The idle energy storage information of the corresponding energy storage device can be determined according to the difference between the actual stored energy and the rated stored energy. In this embodiment, the idle energy storage information refers to the size of the remaining energy storage space. Traverse the current energy storage information corresponding to each energy storage device in the energy storage device cluster, and calculate the difference between the current energy storage information of each energy storage device and the corresponding rated stored energy to determine the idle energy storage information of each energy storage device.

[0066] S230. Based on the idle energy storage information of each energy storage device in the energy storage device cluster, determine at least one first energy storage device that matches the power surplus amount, where the sum of the idle energy storage information of the at least one first energy storage device is greater than or equal to the power surplus amount.

[0067] Specifically, the energy storage device that matches can be selected from the energy storage device cluster according to the power surplus amount. Specifically, match the power surplus amount with the idle energy storage information of each energy storage device to match at least one first energy storage device that can meet the power surplus amount, and the sum of the idle energy storage information of the at least one first energy storage device that is matched is greater than or equal to the power surplus amount.

[0068] Optionally, determining at least one first energy storage device that matches the power surplus amount based on the idle energy storage information of each energy storage device in the energy storage device cluster includes: arranging the idle energy storage information of each energy storage device in descending order, and sequentially selecting at least one first energy storage device according to the arrangement order. When the sum of the idle energy storage information of the at least one first energy storage device selected is greater than or equal to the power surplus amount, stop selecting the first energy storage device to obtain at least one first energy storage device that matches the power surplus amount.

[0069] Specifically, the idle energy storage information of each energy storage device is sorted in descending order, the priorities of the corresponding energy storage devices are set according to the sorting results, and the first energy storage device is sequentially selected according to the priorities until the sum of the idle energy storage information of at least one selected energy storage device is greater than or equal to the power surplus amount, and the selection of the first energy storage device is stopped, so as to obtain at least one first energy storage device that matches the power surplus amount. By screening the energy storage devices according to the descending order of the idle energy storage information of each energy storage device, it is possible to store the surplus power resources with the smallest number of energy storage devices, avoid the waste of the energy storage resources of the energy storage devices, and improve the utilization rate of the energy storage devices.

[0070] S240. In the case where the power supply and demand state is a power deficit, at least one second energy storage device that matches the power deficit amount is determined based on the current energy storage information of each energy storage device in the energy storage device cluster, where the sum of the current energy storage information of the at least one second energy storage device is greater than or equal to the power deficit amount.

[0071] Specifically, in the case where the power supply and demand state is a power deficit, the energy storage devices that match can be selected from the energy storage device cluster according to the power deficit amount. Specifically, the power deficit amount is matched with the current energy storage information of each energy storage device, and at least one second energy storage device that can meet the power deficit amount is matched, that is, the sum of the pre-energy storage information of the at least one second energy storage device is greater than or equal to the power surplus amount, so as to obtain at least one second energy storage device that matches the power deficit amount.

[0072] S250. Control at least one first energy storage device to store the surplus power resources, or control at least one second energy storage device to release the power resources based on the power deficit amount.

[0073] The technical solution of this embodiment is to obtain the power supply and demand status of the target power system, where the power supply and demand status includes any one of power balance, power surplus, and power deficit; in the case of power surplus in the power supply and demand status, obtain the current energy storage information corresponding to each energy storage device in the energy storage device cluster, and determine the idle energy storage information of the energy storage device based on the current energy storage information of the energy storage device; based on the idle energy storage information of each energy storage device in the energy storage device cluster, determine at least one first energy storage device that matches the power surplus amount, where the sum of the idle energy storage information of at least one first energy storage device is greater than or equal to the power surplus amount; in the case of power deficit in the power supply and demand status, based on the current energy storage information corresponding to each energy storage device in the energy storage device cluster, determine at least one second energy storage device that matches the power deficit amount, where the sum of the current energy storage information of at least one second energy storage device is greater than or equal to the power deficit amount; control at least one first energy storage device to store surplus power resources, or control at least one second energy storage device to release power resources based on the power deficit amount. This technical solution realizes that when the power system is in different power supply and demand states, according to the power surplus amount or power deficit amount in the current supply and demand state and the current energy storage information of the energy storage device, the energy storage devices used for regulation are screened out from the energy storage device cluster to obtain multiple energy storage devices that conform to the actual operation of the power system, which are used to store power resources or release power resources, solves the problem of unable to accurately, quickly, and flexibly and effectively regulate the energy storage device according to the actual operation of the power system, and the problem of poor utilization rate of the energy storage device, and also fully considers the energy storage information of the energy storage device itself, improves the reasonable regulation of the energy storage device in the power system, the control efficiency of the energy storage device and the utilization rate of the energy storage device, so that the power system can be controlled in a power balance state in real time and effectively, and the stable operation of the power system is ensured.

[0074] Embodiment III

[0075] Figure 3 FIG. is a flowchart of a method for determining power supply and demand data provided in Embodiment III of the present invention. This embodiment is applicable to the situation of determining power supply and demand data. This method can be executed by a power supply and demand data determining device, which can be implemented in the form of hardware and / or software. The power supply and demand data determining device can be configured in electronic devices such as servers and computers, or can be configured in the electronic device provided in the embodiment. As Figure 3 shown, the method includes:

[0076] S310. Obtain the characteristic information corresponding to the target power system, where the characteristic information includes power source characteristic information and load characteristic information.

[0077] Among them, the characteristic information can be specifically understood as data representing the operating conditions of the power system. The characteristic information includes power source characteristic information and load characteristic information. Among them, the power source characteristic information represents data on the operating conditions of power generation side equipment, including but not limited to the power generation method and output information based on time series. The output information represents the electric energy that a generator set can output within a preset time period, also known as the power generation output. The time period can be understood as the interval time between time series, which can be 1 second, 1 minute, 1 hour, one day, etc., and is set according to the actual situation and is not limited here. The load characteristic information represents data on the operating conditions of load side equipment, including but not limited to the load type and power consumption information based on time series. The load type can be classified according to electrical equipment or according to application scenarios. The load type includes but not limited to lighting power consumption load, network loss load, electrothermal load, and rectifier load. The power consumption information specifically refers to the power consumption corresponding to different load types.

[0078] Specifically, the characteristic information corresponding to the target power system can be obtained from the target storage space in the server in real time, or the power source characteristic information and load characteristic information in the power system can be collected in real time through data collection devices. Among them, corresponding data collection devices are set on both the power source side and the load side, and the collected information can be transmitted to the server in real time. After preprocessing such as data cleaning and data verification on the collected data, the characteristic information corresponding to the target power system is obtained.

[0079] In this embodiment, obtaining the power source characteristic information and load characteristic information of the target power system provides a data basis for subsequent determination of the power supply and demand status of the power system, ensuring the accuracy and real-time nature of the power supply and demand status.

[0080] S320. Determine the power supply and demand status of the target power system based on the power source characteristic information and load characteristic information in the characteristic information. Among them, the power source characteristic information includes the power generation method and output information, and the load characteristic information includes the load type and power consumption information.

[0081] Among them, the power supply and demand state can be specifically understood as representing the power supply and demand state of power resources on the power generation side and the load side, including any one of power balance, power surplus, and power deficit. It should be noted that power balance, power surplus, and power deficit can be represented by characters to only represent a state, or can be represented by numerical values with positive and negative signs for power balance, power surplus, and power deficit. Preferably, if the numerical value is 0, it represents that the power supply and demand state is power balance; if the numerical value is positive, it represents that the power supply and demand state is power surplus, and the corresponding numerical value represents the power surplus amount; if the numerical value is negative, it represents that the power supply and demand state is power deficit, and the corresponding numerical value represents the power deficit amount. The power generation method refers to the method of generating electric energy on the power generation side, including but not limited to wind power generation, photovoltaic power generation, and tidal power generation. The output information refers to the electric energy that the corresponding power generation method can output within a preset time period. The output information is information based on a time series. The preset time period can be set based on the time interval between adjacent time points in the time series, can be set based on a time period composed of one or more time intervals, and can also be set according to actual needs.

[0082] Specifically, when the power source characteristic information and the load characteristic information are obtained, both the output information in the power source characteristic information and the power consumption information in the load side characteristic information are data based on a time series. Then, it is necessary to align the power source characteristic information and the load characteristic information according to the time information, project the power source characteristic information and the load characteristic information onto the same time axis based on the time series, so as to facilitate the comparison of the output information in the power source characteristic information and the power consumption information in the load side characteristic information. The difference between the output information and the power consumption information in the same time period can be calculated, and the corresponding power supply and demand state can be determined according to the difference. It is set that when the output information is greater than the power consumption information, the corresponding power supply and demand state is determined to be supply greater than demand, that is, power surplus; when the output information is less than the power consumption information, the corresponding power supply and demand state is determined to be supply less than demand, that is, power deficit; when the output information is equal to the power consumption information, it is power balance. Among them, the difference between the output information and the power consumption information is the corresponding power surplus amount or power deficit amount.

[0083] In some embodiments, the power supply and demand state determination model that has been pre-trained can also be used. The power source characteristic information and the load characteristic information are used as the input information of the power supply and demand state determination model, and the power supply and demand state determination model determines the power supply and demand state result, that is, the power supply and demand state corresponding to the power source characteristic information and the load characteristic information is obtained.

[0084] S330. When the power supply and demand state is power surplus or power deficit, obtain the predicted output information, determine the power quantity supply and demand data based on the predicted output information and the load characteristic information, and send the power quantity supply and demand data to the edge computing module corresponding to the energy storage device.

[0085] Specifically, in the case where the power supply and demand state is power surplus or power deficit, obtain the predicted output information. Calculate the difference result between the predicted output information and the load characteristic information, and determine the power quantity supply and demand data based on the difference result. That is, if the difference result is positive, the absolute value of the difference is the power surplus quantity, and if the difference result is negative, the absolute value of the difference is the power deficit quantity. It is also possible to process the predicted output information and the load characteristic information in a pre-trained power quantity supply and demand data determination model to obtain the power quantity supply and demand data. Optionally, obtaining the predicted output information includes: obtaining the predicted environment information on the power generation side, and performing prediction processing on the predicted environment information based on a pre-set output information prediction algorithm to determine the predicted output information corresponding to the predicted environment information. Specifically, a pre-constructed environment information-output information mapping relationship can be obtained, and based on the obtained predicted environment information on the power generation side, matching is performed in the pre-constructed environment information-output information mapping relationship to determine the output information that matches the predicted environment information, and the obtained output information is used as the predicted output information corresponding to the predicted environment information. It is also possible to call a pre-trained output information prediction model, use the obtained predicted environment information on the power generation side as the input parameter of the output information prediction model, and after being processed by the output information prediction model, output the predicted output information corresponding to the predicted environment information. Among them, the output information prediction model is a neural network prediction model. Send the power quantity supply and demand data to the edge computing module corresponding to the energy storage device.

[0086] The technical solution of this embodiment is to obtain the characteristic information corresponding to the target power system, where the characteristic information includes power source characteristic information and load characteristic information; determine the power supply and demand state of the target power system based on the power source characteristic information and the load characteristic information in the characteristic information, where the power source characteristic information includes the power generation method and the output information, and the load characteristic information includes the load type and the power consumption information; in the case where the power supply and demand state is power surplus or power deficit, obtain the predicted output information, determine the power quantity supply and demand data based on the predicted output information and the load characteristic information, and send the power quantity supply and demand data to the edge computing module corresponding to the energy storage device. This technical solution determines the power supply and demand state of the target power system according to the characteristic information of the target power system, and then determines the power surplus quantity or the power deficit quantity information corresponding to the power system in different power supply and demand states, realizing the ability to determine the power quantity supply and demand data in real time according to the characteristic information of the power system, enabling the subsequent determination of an effective regulation strategy for the energy storage device based on the power quantity supply and demand data, improving the utilization rate of the energy storage device, ensuring the supply and demand balance of the power system, and helping to improve the control efficiency of the power balance of the power system.
