摘要：
Droop control is one of the basic control methods to solve the problem of load sharing in DC microgrids. However, the conventional droop control cannot balance the current sharing accuracy and bus voltage regulation between microsources(MSs). To tackle this problem, the ideal output current of each MS can be obtained based on the dynamic consensus algorithm. Then an improved droop control method that changes the droop coefficient by fuzzy control is proposed to improve the robustness of the system. The bus voltage can be effectively controlled while the currents are accurately shared. Finally, the effectiveness and superiority of the proposed droop control strategy are verified by MATLB/SIMULINK simulation.
