In the wind-photovoltaic (PV)-storage DC microgrid, the use of droop control ensures theproportional power sharing between parallel power sources without the need for communication betweenthe sources. However, the traditional droop control does not enable the output of the maximum PV andwind turbine (WT) power. Therefore, this paper proposes an improved droop control method that com⁃bines the maximum power point tracking (MPPT) algorithm with droop control. The method can notonly ensure that PV and WT output the maximum power, but also realize the power sharing with the en⁃ergy storage system (ESS). In order to verify the effectiveness of the improved method, we conductedsimulations using MATLAB / Simulink and compared it with the traditional droop control method. Thesimulation results showed that in a typical system consisting of 5 kW PV, 7.34 kW WT and 10 kWload, under the same operating environment, the improved droop control method could increase the PVpower supply ratio up to 8%, the WT power supply share by up to 9%, and the battery energy storageshare by up to 10%, while the DC bus voltage fluctuation was basically unchanged. The improveddroop control method has obvious advantages over the traditional method in the wind-PV-storage DCmicrogrid, which is of great significance for improving the overall performance and reliability of the system.
