Inverter parallel control method

The invention discloses an inverter parallel control method, which is used for realizing optimal control on a plurality of inverters in a parallel operation scene, and comprises the following steps: pre-determining rated parameters of each inverter and an inverter parallel system, and configuring initial control parameters of the parallel system according to the rated parameters; obtaining all inverters in the inverter parallel system and operation parameters of the inverter parallel system in the operation process; determining corresponding virtual impedance for each inverter based on the acquired operation parameters and load information in the operation process; determining a droop control parameter of each inverter according to the determined virtual impedance; and configuring operation control parameters of each inverter based on the determined droop control parameters and the initial control parameters. According to the inverter parallel control method provided by the embodiment of the invention, the ou
