[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] The power control method provided in the embodiment of the present application can be applied in the application environment shown in FIG1 . Among them, the energy storage management terminal 101 and the power grid management terminal 102 both communicate with the server 103 through the network. The data storage system can store the data that the server 103 needs to process. The data storage system can be integrated on the server 103, or it can be placed on the cloud or other network servers.

[0046] When power regulation is required, first, the energy storage management terminal 101 sends a first power regulation request to the server 103, and the power grid management terminal 102 sends a second power regulation request to the server 103. The first power regulation request includes power supply data of multiple energy storage devices and the first virtual resource data required for power transfer corresponding to each energy storage device, and the second power regulation request includes power demand data of multiple distribution network systems. Secondly, the server 103 determines the power regulation strategy data based on the power supply data, the power demand data and the first virtual resource data. The power regulation strategy data includes multiple power transfer relationships, and each power transfer relationship is used to indicate the energy storage device corresponding to the starting end of the power transfer and the distribution network system corresponding to the destination end of the power transfer. Thirdly, the server 103 generates multiple order information for power transfer based on the multiple power transfer relationships. Finally, the server 103 sends multiple order information to the energy storage management terminal and the power grid management terminal.

[0047] The energy storage management terminal 101 and the power grid management terminal 102 may be, but are not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices and portable wearable devices. IoT devices may be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The server 103 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0048] Figure 2 This is a schematic diagram of the structure of a power control system provided in an embodiment of the present application. Figure 2 As shown, the power control system includes: an energy storage management terminal 101, a power grid management terminal 102, a server 103, an energy storage device 104 and a power grid system 105.

[0049] Among them, the energy storage management terminal 101 is used to collect information about the energy storage device 104, and the power grid management terminal 102 is used to collect information about the power grid system 105. A cloud energy storage service system platform is set up on the server 103. The cloud energy storage system interacts with the energy storage management terminal 101 and the power grid management terminal 102 to build a valuable information transmission channel between the distributed energy storage device 104 and the power grid system 105 to achieve flexible scheduling of energy storage. Under the power control strategy, the distributed energy storage device 104 and the power grid system 105 realize the power transfer between each subject through the cloud platform.

[0050] In some embodiments, data monitoring interfaces such as voltage transformers, current sensors, and temperature and humidity sensors are installed inside the energy storage device 104, and a battery management module of the energy storage device 104 is constructed to obtain various parameters of each battery module in the energy storage device 104 and monitor the battery condition and operating status of the energy storage device.

[0051] In some embodiments, the energy storage management terminal 101 collects the power supply data of the energy storage device 104 and the first virtual resource data required for power transfer and uploads them to the cloud in real time through a first power control request, so as to perform joint scheduling under the scheduling of the server according to the power status of the energy storage device 104. Correspondingly, the power grid management terminal 102 collects the power demand data of the distribution network system and reports it to the server 103 through a second power control request.

[0052] In some embodiments, the server 103 constructs a cloud energy storage integrated management platform with the help of technologies such as big data, cloud computing, and the Internet of Things. The cloud energy storage integrated management platform can achieve comprehensive cloud energy storage services and optimal configuration of electric energy after obtaining the power supply data of the energy storage device and the first virtual resource data required for power transfer through the energy storage management terminal 101, and obtaining the power demand data of the distribution network system through the power grid management terminal 102.

[0053] In one embodiment, Figure 3 As shown, a power control method is provided, and the method is applied to the server in FIG. 1 as an example for description, including S201-S204:

[0054] S201. Receive a first power control request sent by an energy storage management terminal and a second power control request sent by a power grid management terminal.

[0055] The first power control request includes power supply data of multiple energy storage devices and first virtual resource data required for power transfer corresponding to each energy storage device, and the second power control request includes power demand data of multiple distribution network systems.

[0056] It should be understood that the power transfer involved in the embodiment of the present application can be the power transmission between the energy storage device and the distribution network system during load peaks and valleys. The above power supply data refers to the power that the energy storage device can provide, and the above power demand data refers to the power required by the distribution network system. The first virtual resource data refers to the amount of virtual resources gained per unit of power through resource transfer during load peaks and valleys.

[0057] In some embodiments, each energy storage device may correspond to an energy storage management terminal, and accordingly, each energy storage management terminal may collect the operation data of the corresponding energy storage device, thereby determining the power supply data and the first virtual resource data of the corresponding energy storage device. Similarly, each distribution network system may correspond to a power network management terminal, and accordingly, each power network management terminal may collect the operation data of the corresponding distribution network system, thereby determining the power demand data of the corresponding distribution network system.

[0058] In other embodiments, multiple energy storage devices may correspond to the same energy storage management terminal, and accordingly, the energy storage management terminal may aggregate the operating data of multiple energy storage devices, thereby respectively determining the power supply data and the first virtual resource data of each energy storage device. Similarly, multiple distribution network systems may correspond to one power network management terminal, and accordingly, the power network management terminal may aggregate the operating data of multiple distribution network systems, thereby respectively determining the power demand data of each distribution network system.

[0059] The energy storage device mentioned above may be various energy storage power stations, such as an electrochemical energy storage power station.

[0060] It should be understood that the embodiments of the present application do not impose any restrictions on when the energy storage management terminal sends the first power control request and when the power grid management terminal sends the second power control request. In some embodiments, the first power control request and the second power control request can be sent to the server in real time. In other embodiments, a fixed-point power control cycle can be set, and the first power control request and the second power control request are sent to the server at a set time point before the start of each power control cycle. Exemplarily, the power control cycle can be set to a day, and the first power control request and the second power control request can be sent to the server at 10 o'clock in the evening of the previous day.

[0061] In other embodiments, after receiving the first power control request sent by the energy storage management terminal and the second power control request sent by the power grid management terminal, the server can verify the power control authority of multiple energy storage devices and multiple distribution network systems. If it is verified that the power control authority is not possessed, the server can discard the power supply data and the first virtual resource data of the energy storage device that does not have the power control authority, and the power demand data of the distribution network system that does not have the power control authority. If it is verified that the power control authority is possessed, the server continues to perform power control based on the first power control request and the second power control request.

[0062] It should be understood that the embodiments of the present application do not limit how to verify the power control authority. In some embodiments, the server can obtain the contract information of the corresponding power control types of multiple energy storage devices and multiple distribution network systems respectively. Subsequently, the server verifies the power control authority of multiple energy storage devices and multiple distribution network systems respectively according to the contract information.

[0063] Exemplarily, the energy storage service provider formulation platform on the server can formulate operating rules, including the rights, power control rules, service processes, rules and regulations that the energy storage device and the distribution network system have in the energy storage service provider formulation platform. Subsequently, if the energy storage device and the distribution network system need to perform power control, a contract request can be sent to the server to generate corresponding contract information. When performing power control, the server determines the power control authority of multiple energy storage devices and multiple distribution network systems by verifying the contract information. For energy storage devices and distribution network systems with power control authority, power control can be performed. For energy storage devices and distribution network systems that do not have power control authority, the power control queue can be removed, and the power supply data and first virtual resource data of the energy storage device that does not have power control authority, as well as the power demand data of the distribution network system that does not have power control authority, are discarded.

[0064] In some embodiments, after receiving the first power control request and the second power control request, the server may further integrate and publish the power supply data, power demand data and the first virtual resource data therein according to time periods.

[0065] S202: Determine power control strategy data according to power supply data, power demand data and first virtual resource data.

[0066] The power control strategy data includes a plurality of power transfer relationships, each of which is used to indicate the energy storage device corresponding to the starting end of the power transfer and the distribution network system corresponding to the destination end of the power transfer.

[0067] In this step, after receiving the first power control request and the second power control request, the server may also determine power control strategy data according to the power supply data, the power demand data and the first virtual resource data.

[0068] It should be understood that the embodiments of the present application do not limit how to determine the power control strategy data based on the power supply data, the power demand data and the first virtual resource data. In some embodiments, the server may first obtain preset power dispatch rule data, and the power dispatch rule data is used to indicate the mapping relationship between the power supply data and the first virtual resource data and the power demand data, respectively. Subsequently, the server may match multiple energy storage devices and multiple distribution network systems according to the power dispatch rule data, the power supply data, the power demand data and the first virtual resource data, and determine multiple power transfer relationships. Finally, the server may summarize multiple power transfer relationships to generate power control strategy data.

[0069] The above-mentioned preset power dispatch rule data may be pre-set to determine the mapping relationship between the power supply data and the first virtual resource data and the power demand data respectively.

[0070] Exemplarily, using the preset power dispatch rule data, the first virtual resource data of each energy storage device can be centrally bid in combination with the power supply data and power demand data. Based on the mapping relationship indicated by the power dispatch rule data, it can be determined whether there is a distribution network system that matches the energy storage device. If so, the energy storage device bids successfully, and then a power transfer relationship between the successfully matched energy storage device and the distribution network system can be generated. By combining multiple power transfer relationships, the final power control strategy data can be formed, and the power control strategy data can be the final dispatch result.

[0071] S203. Generate multiple order information of electricity transfer according to multiple electricity transfer relationships.

[0072] In this step, after the server determines the power regulation strategy data according to the power supply data, the power demand data and the first virtual resource data, it can generate multiple order information of power transfer according to multiple power transfer relationships.

[0073] In some embodiments, the power control strategy data also includes the resource transfer amount corresponding to each power transfer relationship; accordingly, the above order information includes not only the corresponding power transfer relationship, but also the resource transfer amount corresponding to the power transfer relationship.

[0074] S204: Send multiple order information to the energy storage management terminal and the power grid management terminal.

[0075] In the present application, after the server generates multiple order information for electric energy transfer, the multiple order information can be sent to the energy storage management terminal and the power grid management terminal.

[0076] In some embodiments, if multiple energy storage devices can correspond to one energy storage management terminal, and multiple distribution network systems correspond to one grid management terminal, multiple order information can be directly sent to the energy storage management terminal and the grid management terminal. If each energy storage device corresponds to one energy storage management terminal, and each distribution network system corresponds to one grid management terminal, the order information can be sent to the energy storage management terminal corresponding to the energy storage device for the power transfer involved in the order, and the grid management terminal corresponding to the distribution network system for the power transfer involved in the order.

[0077] In some embodiments, the order information also includes power transmission credential information, which is used to verify the energy storage device corresponding to the starting end of the power transfer and the distribution network system corresponding to the destination end of the power transfer when the power is transferred.

[0078] For example, before executing the power transfer corresponding to the order information, the power transfer certificate information can be used to verify whether the energy storage device and distribution network system for the power transfer are determined. If correct, the power transfer will continue and the power delivery will be completed. If incorrect, the information power transfer will be stopped.

[0079] In some embodiments, after sending multiple order information to the energy storage management terminal and the power grid management terminal to transfer electricity, the server can also determine the first virtual resource data corresponding to each electricity transfer relationship based on the energy storage device corresponding to the starting end of the electricity transfer indicated by each electricity transfer relationship. Subsequently, the server can determine the second virtual resource data corresponding to each energy storage device based on the resource transfer amount corresponding to each electricity transfer relationship and the first virtual resource data corresponding to each electricity transfer relationship.

[0080] The second virtual resource data is used to represent the total amount of virtual resources interacted by the energy storage device during the power transfer process.

[0081] Exemplarily, after the power transfer is completed, the amount of resource transfer transferred by the order information corresponding to each power transfer relationship can be determined. In addition, since the first virtual resource data required for the power transfer is proposed by the energy storage device, the first virtual resource data corresponding to each power transfer relationship can be determined by querying the energy storage device corresponding to the starting end of the power transfer indicated by each power transfer relationship. Subsequently, the server can multiply the first virtual resource data corresponding to each power transfer relationship by the amount of resource transfer transferred by each power transfer relationship to obtain the amount of virtual resources generated by each power transfer. The amount of virtual resources generated by each power transfer is summarized to obtain the second virtual resource data. That is, the server realizes a settlement that benefits all parties.

[0082] The power control method provided in the embodiment of the present application first receives a first power control request sent by an energy storage management terminal and a second power control request sent by a power grid management terminal. The first power control request includes power supply data of multiple energy storage devices and first virtual resource data required for power transfer corresponding to each energy storage device, and the second power control request includes power demand data of multiple distribution network systems. Secondly, according to the power supply data, the power demand data and the first virtual resource data, the power control strategy data is determined. The power control strategy data includes multiple power transfer relationships, and each power transfer relationship is used to indicate the energy storage device corresponding to the starting end of the power transfer and the distribution network system corresponding to the destination end of the power transfer. Thirdly, according to the multiple power transfer relationships, multiple order information for power transfer is generated. Finally, multiple order information is sent to the energy storage management terminal and the power grid management terminal. By matching the power supply data, the power demand data and the first virtual resource data required for power transfer, order information corresponding to multiple power transfer relationships between the energy storage device and the distribution network system is generated, so that the energy storage device and the distribution network system are transferred based on the order information, and then multiple energy storage power stations can be effectively regulated on a large scale.

[0083] The following describes how to determine the power control strategy data. Figure 4 A flow chart of another power control method provided in an embodiment of the present application is shown as follows: Figure 4 As shown, the power control method includes S301-S306:

[0094] S402: Determine power control strategy data according to power supply data, power demand data and first virtual resource data.

[0095] The power control strategy data includes a plurality of power transfer relationships, each of which is used to indicate the energy storage device corresponding to the starting end of the power transfer and the distribution network system corresponding to the destination end of the power transfer.

Thirdly, according to the multiple power transfer relationships, multiple order information for power transfer is generated. Finally, multiple order information is sent to the energy storage management terminal and the power grid management terminal. By matching the power supply data, the power demand data and the first virtual resource data required for power transfer, order information corresponding to multiple power transfer relationships between the energy storage device and the distribution network system is generated, so that the energy storage device and the distribution network system are transferred based on the order information, and then multiple energy storage power stations can be effectively regulated on a large scale.
