Current sharing is one of the key issues for parallel operation of the autonomous inverter-dominated microgrid. A new method of current droop control with zero output impedance is presented. Different from the conventional power droop control, the proposed solution uses the current as the droop control variable, and thus there is no need of the instantaneous power calculation. Also, the closed-loop PR control is designed to ensure the zero output impedance of inverter, which mitigates the effect of inverter output impedance on current sharing. Theoretical analysis, simulation and experimental results verify the effectiveness of the proposed method.
