Abstract: In view of the contradiction between the distribution accuracy of distributed generation （DG） output powers and high voltage level in the traditional droop control of DC microgrid,a DC-microgrid droop control based on double voltage compensation is proposed in this paper. The method is based on the centralized secondary control and the peer-topeer droop control strategy,and double voltage loop control is designed into the secondary control. The first voltage loop ensures high accuracy distribution of load power,and the second voltage loop raises the system voltage closer to the rated value. The strategy makes DC microgrid system have good steady state and dynamic characteristics,can realize the accurate distribution of output power among converters with different capacity,and can deal with local load mismatch. The simulation results show that the proposed control method can ensure good power distribution accuracy,maintain the voltage at a high level,and take into account the dynamic response of the system.
