This paper proposes an effective DC voltage and power sharing droop control structure for DC microgrid based on public bus voltage feedback signal. Firstly, the impact of the line resistance on power sharing among droop controlled distributed generators is analyzed and the reason why the line resistance cannot be ignored is presented. Then, an improved droop control is proposed. The simulation test based on MATLAB/Simulink was implemented to demonstrate the proposed approach.
