In order to solve the problem that the reactive power of microgrid inverters can not be divided equally due to the inconsistency of line impedance, this paper proposes an improved current droop control strategy. To precisely adjust the voltage bias of the reactive current droop curve, in this research, the measured and calculated value of the reactive current at the point of common coupling (PCC) by capacity is used as the reference of all inverters, the bus information is used to control the improved calculus controller. The method can compensate for the voltage drop caused by impedance, which makes the inverter accurately divide load according to capacity, with low communication dependence, no periodic power delay, and good adaptability and stability. Simulation and experiment also fully prove the correctness and feasibility of the proposed control strategy.
