[0051] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0052] Reference Figure 1 , a flow chart of a power intelligent allocation method according to an embodiment of the present application is shown, and the power intelligent allocation method may at least include steps S100-S400:

[0053] S100, obtaining the maximum output power, real-time power supply demand and real-time available power of the home energy storage system of all electrical devices.

[0054] S200: Determine the allocated power of each electrical device according to each maximum output power and the real-time available power.

[0055] S300. When the real-time power demand is greater than the real-time available power, determine the priority of the power-consuming device, determine the target power-consuming device according to the priority, or prompt the user and determine the target power-consuming device in response to the user's selection instruction.

[0056] S400: Reduce the allocated power of the target electrical equipment.

[0057] The technical solution of the embodiment of the present application can initially perform reasonable power allocation by obtaining the maximum output power, real-time power supply demand and real-time available power of all electrical devices, and determining the allocated power of each electrical device according to each maximum output power and real-time available power; when the real-time power supply demand is greater than the real-time available power, determining the priority of the electrical device, and determining the target electrical device according to the priority, or prompting the user and responding to the user's selection instruction to determine the target electrical device, reducing the allocated power of the target electrical device, and realizing intelligent power allocation, which is conducive to more reasonable utilization of resources and ensuring the stability of the operation of electrical equipment.

[0058] In one embodiment, the processor of the home energy storage system can poll each connected electrical device through a bus or communication protocol (such as Modbus, CAN, etc.), confirm the online status of the electrical device, and simulate the operation of the electrical device by applying a standard load, so as to detect the maximum output power of each electrical device. Optionally, the processor can initialize a list of electrical devices, and the maximum output power of each electrical device and the identity corresponding to each electrical device are recorded in the electrical device list for subsequent processing.

[0059] In addition, by setting up sensors or external data sources (such as smart meters), etc., the real-time power demand and the real-time available power of the home energy storage system can be read in real time, and the processor can use these data for subsequent calculations. It should be noted that the real-time power demand refers to the total power required by the home energy storage system at the current moment, including the total power required when all electrical devices in the home are running at the same time; the real-time available power refers to the total power that the current home energy storage system can provide, which is calculated based on the energy storage device (such as a battery), the external power grid power supply, and other available energy sources (such as solar panels, wind power, etc.).

[0060] In one embodiment, step S200 includes steps S210-S230:

[0061] S210: Calculate the sum of the maximum output powers according to each maximum output power.

[0062] Optionally, the sum of the maximum output powers is: Among them, P max , i is the maximum output power of the i-th electrical device, and n is the number of electrical devices.

[0063] S220: respectively determine a power ratio of each maximum output power to the sum of the maximum output powers.

[0064] Optionally, the power ratio value is:

[0065] S230: Determine the allocated power of each electrical device according to the product of the power ratio and the real-time available power.

[0066] Optionally, the calculation formula is:

[0067]

[0068] Among them, P_final,i is the allocated power of the i-th power-consuming device, and P_avail is the real-time available power.

[0069] In one embodiment, in step S300, the real-time power demand is compared with the real-time available power. When the real-time power demand is greater than the real-time available power, it means that the power of the current energy storage system is insufficient to meet the current power demand. At this time, a solution strategy needs to be adopted to determine the priority of the power-consuming equipment, and the target power-consuming equipment is determined according to the priority. Optionally, step S310 or S320 is included:

[0070] S310: Find the priority of each electric device from the preset list, and use the electric device with the lowest priority as the target electric device, or use all electric devices except the electric device with the highest priority as the target electric device.

[0071] Optionally, the user can communicate with the home energy storage system through the terminal in advance, configure the priority of an electrical device in advance, and then the home energy storage system will save the configured content in the preset list. Therefore, the processor can find the priority of each electrical device from the preset list; and the priority level can be set based on user needs, each level can have one or more electrical devices, and the processor can use the electrical device with the lowest priority level as the target electrical device, so the number of target electrical devices can be one or more; or, all electrical devices except the electrical device with the highest priority level are used as target electrical devices.

[0072] S320, prompting the user and responding to the user's setting instruction to set the priority of each electric device, and taking the electric device with the lowest priority as the target electric device.

[0073] Optionally, the home energy storage system provides a display interface for the user to operate on the terminal. When the user has not set the priority and there is no preset list, the user can be prompted to generate a setting instruction to set the priority of each electrical device; then, the electrical device with the lowest priority level is similarly used as the target electrical device.

[0074] In one embodiment, in step S300, when the real-time power demand is greater than the real-time available power, the user can be prompted directly on the display interface to select, for example, an electrical device that needs to reduce power, specifically by selecting an instruction to select, thereby determining the target electrical device. Optionally, the display interface can also display the operating status and power distribution of each electrical device in real time.

[0075] In one implementation, step S400 includes steps S410-S420:

[0076] S410: When the number of the target electric device is one, reduce the allocated power of the target electric device.

[0077] Optionally, when the number of target power-consuming devices is one, the allocated power of the target power-consuming device can be reduced to a certain extent, or the target power-consuming device can be directly turned off to reduce the allocated power to 0. It should be noted that whether to reduce to a certain extent or to turn off directly can be selected by the user in the display page.

[0078] S420: When there are multiple target power-consuming devices, reduce the allocated power of all target power-consuming devices by a preset value or shut down at least one target power-consuming device.

[0079] Optionally, when there are multiple target power-consuming devices at the lowest level, a preset value can be set in advance, and the size of the preset value is not specifically limited. The allocated power of all target power-consuming devices can be reduced by the preset value, or any one or more target power-consuming devices can be directly shut down to reduce the allocated power.

[0080] In one implementation, S400 may include steps S430-S460:

[0081] S430: Determine the power difference between the real-time power supply demand and the real-time available power.

[0082] S440: When the target power-consuming devices are all power-consuming devices except the power-consuming device with the highest priority level, determine the actual number of the target power-consuming devices.

[0083] Optionally, the difference between the real-time power demand and the real-time available power is calculated to obtain the power difference; when the target power-consuming devices are all power-consuming devices except the power-consuming devices with the highest priority level, the actual number of the target power-consuming devices is determined.

[0084] S450: Calculate the ratio of the power difference to the actual number, and determine the power average.

[0085] S460: Reduce the allocated power of each target electrical device by the average power value.

[0086] Optionally, the power average is determined based on the ratio of the power difference to the actual number, and then the allocated power of each target power-consuming device is reduced by the power average, so that the real-time power demand is equal to the real-time available power, ensuring that the real-time available power is sufficient for power supply.

[0087] In one implementation, the power intelligent allocation method of the embodiment of the present application may further include steps S510-S520:

[0088] S510. When the number of target power-consuming devices is one and the allocated power of the target power-consuming devices is reduced, the real-time power demand is greater than the real-time available power, a new target power-consuming device of the previous level corresponding to the priority of the target power-consuming device is determined, and based on the new target power-consuming device, the step of reducing the allocated power of the target power-consuming device is returned until the real-time power demand is less than or equal to the real-time available power.

[0089] Optionally, when the number of target power-consuming devices is one and the allocated power of the target power-consuming devices is reduced, if the real-time power demand is still greater than the real-time available power, a new target power-consuming device of the previous level corresponding to the priority of the target power-consuming device is further determined; similarly, the new target power-consuming device may be one or more, and according to the new target power-consuming device, the step of reducing the allocated power of the target power-consuming device is returned, that is, returning to step S400, until the real-time power demand is less than or equal to the real-time available power.

[0090] S520. When there are multiple target power-consuming devices and the allocated powers of the target power-consuming devices are reduced, the real-time power demand is greater than the real-time available power, the current allocated power is used as the new allocated power, and the step of reducing the allocated powers of all target power-consuming devices by a preset value is returned until the real-time power demand is less than or equal to the real-time available power, or until the allocated powers of all target power-consuming devices are 0. If the real-time power demand is greater than the real-time available power, a new target power-consuming device of the previous level corresponding to the priority of the target power-consuming device is determined, and based on the new target power-consuming device, the step of reducing the allocated powers of all target power-consuming devices by a preset value or shutting down at least one target power-consuming device is returned until the real-time power demand is less than or equal to the real-time available power.

[0091] Optionally, when there are multiple target power-consuming devices and the allocated power of the target power-consuming devices is reduced, if the real-time power demand is still greater than the real-time available power, the current allocated power is used as the new allocated power, and the process of reducing the allocated power of all target power-consuming devices by a preset value is returned, i.e., returning to step S420, until the real-time power demand is less than or equal to the real-time available power. Alternatively, in one embodiment, the process returns to step S420 until the allocated power of all target power-consuming devices is 0, and if the real-time power demand is still greater than the real-time available power, a new target power-consuming device of the previous level corresponding to the priority of the target power-consuming device is determined, and based on the new target power-consuming device, the process of reducing the allocated power of all target power-consuming devices by a preset value or shutting down at least one target power-consuming device is returned, i.e., returning to step S420, until the real-time power demand is less than or equal to the real-time available power.

[0092] In one implementation, the power intelligent allocation method of the embodiment of the present application may further include steps S610-S620:

[0093] S610: Detect the device status of each electrical device in real time.

[0094] S620. When the device status is abnormal, isolate the electrical devices with abnormal device status, and reacquire the maximum output power of all normal electrical devices. Based on the reacquired maximum output power of all normal electrical devices, return to the step of determining the allocated power of each electrical device based on each maximum output power and the real-time available power.

[0095] Optionally, the processor of the home energy storage system detects the device status of each electrical device in real time to understand whether the electrical device has any abnormal situation. If one or more device statuses are abnormal, the electrical devices with abnormal device statuses are isolated to avoid affecting other electrical devices. At the same time, the maximum output power of all normal electrical devices is re-acquired, and based on the re-acquired maximum output power of all normal electrical devices, the process returns to the step of determining the allocated power of each electrical device based on each maximum output power and the real-time available power, i.e., returns to step S200, thereby redetermining the allocated power, releasing the allocation efficiency occupied by the abnormal electrical devices, and ensuring that other electrical devices are allocated power to the greatest extent.

[0096] Through the method of the embodiment of the present application, it is possible to ensure that the energy management of the entire home reaches the optimal power distribution state as much as possible, automatically detects and adjusts, and is more intelligent.

[0104] When there are multiple target power-consuming devices and the allocated power of the target power-consuming devices is reduced, the real-time power demand is greater than the real-time available power, the current allocated power is used as the new allocated power, and the step of reducing the allocated power of all target power-consuming devices by a preset value is returned until the real-time power demand is less than or equal to the real-time available power, or until the allocated power of all target power-consuming devices is 0. If the real-time power demand is greater than the real-time available power, a new target power-consuming device of the previous level corresponding to the priority of the target power-consuming device is determined, and based on the new target power-consuming device, the step of reducing the allocated power of all target power-consuming devices by a preset value or shutting down at least one target power-consuming device is returned until the real-time power demand is less than or equal to the real-time available power.
