[0038] Embodiment 1

[0039] Figure 1 This is a flow chart of a method for controlling an energy storage device provided in Example 1 of the present invention. This embodiment can be applied to the case of controlling an energy storage device, and is used to control the power system to achieve a supply-demand balance state. The 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 an edge computing module corresponding to the energy storage device in the energy storage device cluster, or in a server and an electronic device provided in the embodiment.

[0040] In this embodiment, the target power system includes but is not limited to power generation side equipment, energy storage side equipment and load side equipment. The power generation side equipment can be equipment for generating new energy power resources, including but not limited to wind power generation equipment, photovoltaic power generation equipment and tidal power generation equipment. The power generation side equipment transmits power resources to the energy storage side equipment and the load side equipment. The energy storage side equipment is used to receive the power resources transmitted by the power generation side equipment and transmit the power resources to the load side equipment. The load side equipment is used to receive the power resources transmitted by the power generation side equipment and the energy storage side equipment. In order to optimize the computing power distribution, a corresponding edge computing module is set at each power generation side equipment, each energy storage side equipment and each load side equipment. The corresponding edge computing module is set according to the computing power requirements corresponding to each power generation side equipment, each energy storage side equipment and each load side equipment. By allocating the corresponding computing power on demand, the optimization of the new energy grid calculation and the control of the computing power cost are realized. The energy storage device control method 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] like Figure 1 As shown, the method includes:

[0042] S110. Obtaining a power supply and demand state of a target power system, wherein the power supply and demand state 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, and 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 state specifically represents the balance state between 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 state between 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 state includes any one of power balance, power surplus and power shortage. The 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. The power surplus represents the state that the power resources provided by the power generation side are more than the power resources required by the load side. The power shortage represents the state that 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 state can be obtained in real time from the cloud server corresponding to the target power system, or the power supply and demand state sent by the cloud server can be received regularly.

[0044] Specifically, if the power supply and demand status of the power system is to be able to be mastered in real time, the power supply and demand status of the target power system can be obtained from the corresponding cloud server in real time, wherein the power supply and demand status includes any one of power balance, power surplus and power shortage. Determine the control strategy for the energy storage device under different supply and demand states to control the power system to be in a supply and demand balance state. It should be noted that when the power supply and demand state is power balance, no processing is required to maintain the operating state of the power system, wherein the control strategy includes a combination of energy storage devices 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 timely determine the control strategy of the energy storage device according to the power supply and demand status to ensure that the target power system is in a power balance state, which helps to improve the stability of the power system operation.

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

[0047] Among them, the power surplus represents the amount of power resources provided by the power generation side in excess of the power resources required by the load side, that is, the amount of power resources used for storage and processing. The energy storage device cluster includes multiple energy storage devices, which are used to meet the power system's storage needs for power resources and to provide the missing power resources for the load side. Energy storage information represents energy storage parameters related to energy storage devices. Energy storage information includes but is not limited to stored energy and storage capacity. Stored energy represents the actual storage capacity in the energy storage device, and storage capacity represents the rated storage capacity of the energy storage device. Energy storage devices for storing surplus power resources are selected from the energy storage device cluster. At least one energy storage device can be randomly selected from the energy storage device cluster. If it is determined that the selected energy storage device cannot meet the storage demand for power resources with a surplus power amount based on the current energy storage information of the selected energy storage device, it is necessary to continue to select energy storage devices until the selected multiple energy storage devices can meet the storage demand for power resources with a surplus power amount. The corresponding priority can also be determined according to the current energy storage information of each energy storage device, and energy storage devices are selected in sequence according to the priority until the selected energy storage device can meet the storage demand for power resources with a surplus power amount. Preferably, the size of the available storage space can be determined according to the current energy storage information of each energy storage device, and the available storage space can be arranged in descending order. The priority of the corresponding energy storage device can be set according to the sorting result, and the energy storage device can be selected in sequence according to the priority until the storage space of at least one selected energy storage device can meet the storage demand for power resources with a surplus power amount. The surplus power can also 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 an energy storage device used to characterize the energy storage device for performing power resource storage processing, specifically to be distinguished from the energy storage device for performing power resource release processing.

[0048] Specifically, after the edge computing module corresponding to the energy storage device side identifies the received power supply and demand state, if it identifies that the power supply and demand state is a surplus of power, it can obtain the surplus of power of the target power system, and use the surplus of power as a screening constraint to screen out energy storage devices that can match the surplus of power from the energy storage device cluster. If it is determined based on the current energy storage information of any selected energy storage device that none of the energy storage devices can meet the storage demand corresponding to the surplus of power, then two energy storage devices are selected. If the two energy storage devices also cannot meet the storage demand corresponding to the surplus of power, then continue to select until the selected multiple energy storage devices can meet the storage demand corresponding to the surplus of power, thereby obtaining at least one first energy storage device that meets the storage demand corresponding to the surplus of power, which is used to store surplus power resources, wherein the selection of energy storage devices can be random selection or selection according to the priority of the energy storage devices. When at least one energy storage device is determined, at least one first energy storage device is controlled to store surplus power resources so that the supply and demand state of the power system tends to a balanced state.

[0049] In this embodiment, when it is identified that the power supply and demand state is surplus power, the surplus power of the target power system is used as a constraint condition, and 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 achieves matching of energy storage devices that meet the surplus power according to the current energy storage information of the energy storage devices, avoids waste of power resources, and can carry the storage demand for surplus power according to the current energy storage information of the energy storage devices, thereby improving the utilization rate of the energy storage devices and avoiding waste of storage resources.

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

[0051] The power shortage represents the amount of power resources that are lacking in the power resources provided by the power generation side compared to the power resources required by the load side, that is, the amount of power resources that need to be released by the energy storage device. The energy storage device used for power resource release is selected from the energy storage device cluster, and the power shortage is used as a constraint condition. The current energy storage information of each energy storage device in the energy storage device cluster can be matched with the power shortage. One energy storage device can be randomly selected from the successfully matched energy storage devices for releasing power resources. If a single energy storage device that can meet the power shortage is not matched, two energy storage devices are selected for resource release. If the two energy storage devices also do not meet the power shortage, the energy storage devices are continuously selected until the power resources that can be provided by the selected energy storage device can match the power shortage. The determination condition for successful matching can be set as the sum of the releasable power resources corresponding to the energy storage information of the selected energy storage device meets the power shortage. The energy storage device cluster can also be sorted in descending order according to the actual storage energy corresponding to the current energy storage information of each energy storage device, and the priority of each energy storage device is set according to the sorting result. The energy storage devices are selected in turn according to the priority. When the sum of the releasable power resources corresponding to the energy storage information of the selected energy storage device meets the power shortage, the selection is stopped, and at least one second energy storage device for releasing power resources is obtained to release power resources. The second energy storage device can be understood as an energy storage device used to characterize the power resource release process, specifically to distinguish it from the energy storage device used for power resource storage process.

[0052] Specifically, after identifying the received power supply and demand state, if it is identified that the power supply and demand state is a power shortage, the power shortage amount of the target power system is obtained, and the power shortage amount is used as a screening constraint condition to screen out energy storage devices that can match the power shortage amount from the energy storage device cluster. If the current energy storage information of any energy storage device does not match the power shortage amount, two energy storage devices are selected. If the current energy storage information of the two energy storage devices does not match the power shortage amount, continue to select until the sum of the energy storage information of the selected multiple energy storage devices can match the power shortage amount, thereby obtaining at least one second Energy storage equipment is used to release electric power resources to compensate for the missing electric power resources on the load side, so as to control the power system to be in a state of power balance, wherein the selection of energy storage equipment can be based on preset selection rules, and the selection rules include selection methods and constraints, wherein the selection method can be random selection or selection according to the priority of the energy storage equipment, and the priority of the energy storage equipment can be determined according to the current energy storage information of the energy storage equipment. Preferably, the energy storage values ​​corresponding to the current energy storage information can be arranged in descending order, and the descending order result is used as the priority of the corresponding energy storage equipment. The constraint condition can be that the sum of the energy storage information of the selected multiple energy storage devices can meet the power shortage, and the number of the selected multiple energy storage devices is the least. In the case of determining at least one second energy storage device, at least one second energy storage device is controlled to release electric power resources based on the power shortage, so that the supply and demand state of the power system tends to a balanced state.

[0053] In this embodiment, when it is identified that the power supply and demand state is a power shortage, a constraint condition is set based on the power shortage of the target power system, and energy storage devices are selected from the energy storage device cluster based on 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. This achieves matching of energy storage devices that meet the power shortage based on the current energy storage information of the energy storage devices, avoids waste of resources, and can carry the power resource demand for the power shortage based on the current energy storage information of the energy storage devices, thereby improving the utilization rate of the energy storage devices, helping to improve the speed with which the power system can reach a power balance state and ensure stable operation of the power system.

[0054] On the basis of the above embodiments, information is shared between the edge computing modules 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 also includes: traversing at least one first energy storage device or at least one second energy storage device determined by each edge computing module, and obtaining the device number in at least one first energy storage device or the device number in at least one second energy storage device; classifying and counting at least one first energy storage device or at least one second energy storage device according to the device number, and determining the weight information corresponding to at least one first energy storage device or at least one second energy storage device determined by each edge computing module according to the statistical results; obtaining the number of uses corresponding to each energy storage device in the energy storage device cluster, and adjusting at least one first energy storage device or at least one second energy storage device based on the weight information and / or the number of uses.

[0055] Each energy storage device in the energy storage device cluster is provided with a device number, and the device number of each energy storage device in the same energy storage device cluster is unique. Specifically, information is shared between the edge computing modules 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 at least one first energy storage device or at least one second energy storage device determined by each edge computing module. For at least one first energy storage device determined by each edge computing module, 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 results as the weight data of the corresponding first energy storage device sets. It can be understood that the more the number of sets of first energy storage devices 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, the usage count corresponding to each energy storage device in the energy storage device cluster is obtained, the usage count of each energy storage device in each first energy storage device set and the usage count of energy storage devices outside the set are determined, and the energy storage devices in each first energy storage device set are matched with the energy storage devices outside the set. If the matching condition is met, the energy storage device outside the set that has been successfully matched replaces the energy storage device in the set to obtain an updated first energy storage device, wherein 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 in the set is within a preset range, and that the usage count of the energy storage device outside the set is less than the usage count of the energy storage device in the set, so as to ensure that the goal of storing surplus power resources can be achieved while avoiding the problem of excessive usage of individual energy storage devices, which helps to balance the utilization rate of the energy storage devices and improve the service life of the energy storage devices. Alternatively, the energy storage devices in the first energy storage device set determined by each edge computing module can be adjusted according to the corresponding number of times the energy storage devices are used, and then the adjusted first energy storage device set can be 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, and the energy storage devices in at least one of the initially determined first energy storage devices can be adjusted according to any of the above methods.

[0057] Correspondingly, at least one second energy storage device determined by each edge computing module is traversed to obtain the device number of at least one second energy storage device; at least one second energy storage device is classified and counted according to the device number, and the weight information corresponding to at least one second energy storage device determined by each edge computing module is determined according to the statistical result; the number of uses corresponding to each energy storage device in the energy storage device cluster is obtained, and at least one second energy storage device is adjusted based on the weight information and / or the number of uses, wherein the specific process of adjusting at least one second energy storage device according to the weight information and / or the number of uses can refer to the adjustment process of adjusting at least one first energy storage device, which will not be repeated here.

[0058] In this embodiment, information is shared between edge computing modules corresponding to each energy storage device, and 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 weight information corresponding to at least one first energy storage device or at least one energy storage device, and adjusts at least one first energy storage device or at least one second energy storage device based on the weight information and / or the number of uses. This achieves the ability to store power resources corresponding to the surplus power while avoiding the problem of excessive use of individual energy storage devices, and to provide the load side with power resources that meet the power deficit while avoiding the problem of excessive use of individual energy storage devices. This improves the control efficiency of the power balance of the power system and also improves the service life of the energy storage devices.

[0074] Embodiment 3

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

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

[0077] Among them, the characteristic information can be specifically understood as data that characterizes the operating status of the power system, and the characteristic information includes power characteristic information and load characteristic information. Among them, the power characteristic information characterizes the data of the operating status of the power generation side equipment, including but not limited to the power generation mode and the output information based on the time series. The output information characterizes the electric energy that the generator set can output within the preset time period, also known as the power generation output. The time period can be understood as the interval between the 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 characterizes the data of the operating status of the load side equipment, including but not limited to the load type and the power consumption information based on the time series. The load type can be classified according to the power equipment or the application scenario. The load type includes but is not limited to the lighting power load, the network loss load, the electric heating load and the 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, and the power supply characteristic information and load characteristic information in the power system can be collected in real time through the data acquisition equipment. Corresponding data acquisition equipment is set on the power supply side and the load side, and the collected information can be transmitted to the server in real time. After pre-processing such as data cleaning and data verification of the collected data, the characteristic information corresponding to the target power system is obtained.

[0079] In this embodiment, the power source characteristic information and load characteristic information of the target power system are obtained, which provides a data basis for the subsequent determination of the power supply and demand status of the power system, thereby ensuring the accuracy and real-time performance 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 the load characteristic information in the characteristic information, wherein the power source characteristic information includes the power generation mode 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 the supply and demand state of power resources that characterize the power generation side and the load, including any one of power balance, power surplus and power shortage. It should be noted that power balance, power surplus and power shortage can be used to represent only one state through characters, or can be represented by numerical values ​​with positive and negative signs. Preferably, if the value is 0, it represents that the power supply and demand state is power balance, if the value is a positive number, it represents that the power supply and demand state is power surplus, and the corresponding numerical value represents the power surplus, if the value is a negative number, it represents that the power supply and demand state is power shortage, and the corresponding numerical value represents the power shortage. The power generation mode refers to the mode 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 can be output by the corresponding power generation mode within the preset time period. The output information is information based on the time series. The preset time period can be set based on the time interval of adjacent time points in the time series, and the preset time period can be set based on the time period composed of one or more time intervals. It can also be set according to actual needs.

[0082] Specifically, when the power characteristic information and the load characteristic information are obtained, the output information in the power characteristic information and the power consumption information in the load side characteristic information are both based on time series data, so it is necessary to align the power characteristic information and the load characteristic information according to the time information, and project the power characteristic information and the load characteristic information on a unified time axis based on the time series, so as to facilitate the comparison of the output information in the power 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. When the output information is greater than the power consumption information, the corresponding power supply and demand state is determined to be greater than the 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 less than the demand, that is, power shortage. When the output information is equal to the power consumption information, it is power balance, wherein the difference between the output information and the power consumption information is the corresponding power surplus or power shortage.

[0083] In some embodiments, a pre-trained power supply and demand state determination model can be used to take power supply characteristic information and load characteristic information as input information of the power supply and demand state determination model. The power supply and demand state determination model determines the power supply and demand state result, that is, obtains the power supply and demand state corresponding to the power supply characteristic information and load characteristic information.

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

[0085] Specifically, when the power supply and demand state is a surplus or shortage of power, the predicted output information is obtained. The difference result between the predicted output information and the load characteristic information is calculated, and the power supply and demand data is determined based on the difference result, that is, if the difference result is a positive number, the absolute value of the difference is the surplus of power, and if the difference result is a negative number, the absolute value of the difference is the shortage of power. The predicted output information and the load characteristic information can also be processed in a pre-trained power supply and demand data determination model to obtain the power supply and demand data. Optionally, obtaining the predicted output information includes: obtaining the predicted environment information of the power generation side, predicting the predicted environment information based on a preset output information prediction algorithm, and determining the predicted output information corresponding to the predicted environment information. Specifically, a pre-constructed environment information-output information mapping relationship can be obtained, and the output information matching the predicted environment information can be matched based on the obtained predicted environment information of the power generation side from the pre-constructed environment information-output information mapping relationship, and the output information matched with the predicted environment information can be determined, and the obtained output information can be used as the predicted output information corresponding to the predicted environment information. The pre-trained output information prediction model can also be called, and the predicted environmental information of the power generation side obtained is used as the input parameter of the output information prediction model. After being processed by the output information prediction model, the predicted output information corresponding to the predicted environmental information is output. The output information prediction model is a neural network prediction model. The power supply and demand data is sent to the edge computing module corresponding to the energy storage device.

[0086] The technical solution of this embodiment obtains characteristic information corresponding to the target power system, wherein the characteristic information includes power characteristic information and load characteristic information; determines the power supply and demand state of the target power system based on the power characteristic information and load characteristic information in the characteristic information, wherein the power characteristic information includes power generation mode and output information, and the load characteristic information includes load type and power consumption information; when the power supply and demand state is power surplus or power shortage, obtains predicted output information, determines power supply and demand data based on predicted output information and load characteristic information, and sends the power 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 or power shortage information corresponding to the power system under different power supply and demand states, thereby realizing the ability to determine the power supply and demand data in real time according to the characteristic information of the power system, so that the effective control strategy of the energy storage device is determined based on the power supply and demand data, thereby 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.
