The invention relates to a micro-grid inverter voltage and current double-ring hanging control method based on virtual impedance. Compared with a three-ring power hanging control, the micro-grid inverter voltage and current double-ring hanging control method based on virtual impedance comprises the steps that: inverter virtual connection impedance Zvir(s) is serially connected between the output current and the reference voltage signals of an inverter; the inverter virtual connection impedance Zvir(s) is equivalent to be a hanging coefficient, so that the output current of the inverter is fed back to the output voltage of the inverter through the virtual connection impedance to be fixed, and further, the purpose of automatically splitting the load power of a parallel inverter system is achieved. The micro-grid inverter voltage and current double-ring hanging control method based on virtual impedance eliminates the defects that a traditional three-ring power hanging controller is sensitive to the connection impedance and the control system is complicated, so that the parallel distributed power supplies in a micro-grid can still realize good power splitting effect when the circuit is short and the impedance is small, the stable margin of the system is improved, and the power supply quality of the loads is ensured.
