[0110] To better understand the photovoltaic energy storage charging system control method provided by the embodiments of the present application, further explanations are given below. It should be understood that the following discussion is only exemplary.

[0111] The present application provides a photovoltaic energy storage charging system control method, and the specific steps can be as Figure 2 shown:

[0112] First, obtain the operation data of each charging pile and the operation data of each photovoltaic energy storage unit.

[0113] In actual implementation, the photovoltaic-storage-charging system may include a controller, at least one charging pile, at least one photovoltaic-storage unit, and an electricity meter. The electricity meter, each charging pile, and each photovoltaic-storage unit are connected to a point of common coupling. The control method of the photovoltaic-storage-charging system can be applied to the controller. The controller can be deployed in any one of the photovoltaic-storage units or charging piles at the point of common coupling.

[0114] In some embodiments, each of the at least one charging piles can be respectively connected to one photovoltaic-storage unit. Each of the at least one photovoltaic-storage units can be respectively connected to one charging pile.

[0115] In actual implementation, the photovoltaic-storage unit may include at least one of an inverter, an energy storage device, a data collector, and a central controller. The charging pile can be an AC charging pile or a DC charging pile.

[0116] In some embodiments, the at least one charging pile, the at least one photovoltaic-storage unit, and the electricity meter can be connected to a point of common coupling. Each charging pile can send the charging pile operation data to the controller through a target communication method, and each photovoltaic-storage unit can send the photovoltaic-storage unit operation data to the controller through the target communication method. The target communication method can be a wired communication method (such as RS485 serial bus, Controller Area Network (CAN), fast Ethernet (FE), Programmable Logic Controller (PLC), etc. wired communication methods), or a wireless communication method (such as wifi frequency band, radio communication technology with a working frequency band below 1 GHz (sub-1g frequency band), etc. wireless communication methods).

[0117] In some embodiments, each charging pile can send the charging pile operation data to the controller based on a target period. Each photovoltaic-storage unit can send the photovoltaic-storage unit operation data to the controller based on a target period. The target period can be a time period of any duration at any time. For example, each charging pile starts from 00:00 every day and sends the charging pile operation data to the controller every 10 minutes. For example, each photovoltaic-storage unit starts from 08:00 every morning and sends the photovoltaic-storage unit operation data to the controller every 5 minutes.

[0118] In some embodiments, the controller can send a notification message to each charging pile and each photovoltaic-storage unit to notify all charging piles and photovoltaic-storage units which charging pile the controller is located in or which photovoltaic-storage unit the controller is located in. The controller can also actively send inquiry messages to all photovoltaic-storage units and charging piles based on a target period, so that all charging piles and photovoltaic-storage units send operation data to the controller.

[0119] In actual implementation, the operation data of each charging pile includes, but is not limited to, the charging pile operation status, the charging pile working mode, the charging pile alarm, the real-time charging current, the real-time charging power, the charging pile current target value, the charging pile power target value, the maximum charging capacity, etc. The operation data of each photovoltaic and energy storage unit includes, but is not limited to, the photovoltaic and energy storage unit operation status, the maximum charge / discharge capacity of the photovoltaic and energy storage unit, the operation mode of the photovoltaic and energy storage unit, the photovoltaic and energy storage unit alarm, the real-time current of the photovoltaic and energy storage unit, the real-time power of the photovoltaic and energy storage unit, the output / input current target value of the photovoltaic and energy storage unit, the output / input power target value of the photovoltaic and energy storage unit, the photovoltaic power, the available status of the remaining charge of the energy storage device, etc.

The monitoring data includes at least one of voltage, current, and power. The voltage can be the voltage at the connection point of the electricity meter, the current can be the current at the connection point of the electricity meter, and the power can be the active power, reactive power, apparent power, etc. at the connection point of the electricity meter.

[0122] In some embodiments, the electricity meter can obtain the monitoring data of the grid connection point through a target connection method with the charging pile or the photovoltaic and energy storage unit. The target connection method can be a wired connection method (such as RS485 serial bus, RS232 serial bus, fast Ethernet (FE), etc. wired connection methods), or a wireless connection method (such as wifi frequency band, radio communication technology with a working frequency band lower than 1 GHz (sub-1g frequency band), etc. wireless connection methods).

[0123] In some embodiments, after obtaining the monitoring data of the electricity meter for the grid connection point, in the case where the operation data of the charging pile sent by the charging pile is not received or the operation data of the photovoltaic and energy storage unit sent by the photovoltaic and energy storage unit is not received, actively obtain the operation data of the charging pile from the charging pile or actively obtain the operation data of the photovoltaic and energy storage unit from the photovoltaic and energy storage unit.

[0124] After obtaining the monitoring data of the electricity meter for the grid connection point, in the case where the value of the monitoring data does not belong to the preset value range, generate and issue a first adjustment instruction for each charging pile based on the operation data of each charging pile, and generate and issue a second adjustment instruction for each photovoltaic and energy storage unit based on the operation data of each photovoltaic and energy storage unit, so as to make the grid connection point reach the preset operation target.

[0125] In actual implementation, the situation where the value of the monitoring data does not fall within the preset value range can be the case where the value of the monitoring data is greater than the maximum preset value, or the case where the value of the monitoring data is less than the minimum preset value.

[0126] In actual implementation, the monitoring data includes at least one of voltage, current, and power.

[0129] In actual implementation, the preset current value can be the current limit value allowed to pass through the grid-connected point.

[0130] In some embodiments, when the grid-connected grid current obtained by the electric meter is greater than the preset current value, the controller can generate and issue a first adjustment instruction for each charging pile based on the operation data of each charging pile. Each charging pile among the charging piles increases the output current or increases the output power based on the first adjustment instruction.

Each photovoltaic energy storage unit among the photovoltaic energy storage units limits the output current, limits the output power, or shuts down based on the second adjustment instruction, so as to achieve current balance at the grid-connected point.

[0131] In some embodiments, when the alarm value of the charging pile or the energy storage unit obtained by the electricity meter is abnormal, or the power value at the grid connection point obtained by the electricity meter is abnormal (for example, the power value is greater than the preset maximum power value or less than the preset minimum power value), a first adjustment instruction for instructing each charging pile to shut down or standby is generated, and a second adjustment instruction for instructing each energy storage unit to shut down or standby is generated.
