Abstract In order to suppress the circulating current from the energy storage device, using the average power sharing control. get the outer ring of power output by the PI control, Superimposed on the converter output AC voltage command as a correction, By Matlab/Simulink software for off-grid simulation analysis to verify the control strategy. Results of this study indicate that adding power balance control in multi-parallel system, which can effectively pre-inverter circulation to ensure that each storage device load sharing to work.
