The indirect current control strategy for grid-connected inverters in distributed generation (DG) systems is investigated in this paper. Conventional grid-connected inverters are normally operated in current control mode in grid-connected time and operated in voltage control mode in stand-alone time, serious transient problem may occur on the output terminal voltage when the inverters change the operating mode. The indirect current control strategy is researched, with the method, the output voltage of the grid-connected inverters can be kept stable during the transient time. The strategy is validated by simulations and experiments.
