Design and analysis of the droop control method for Islanded Microgrid

Abstract

In this paper, a reactive power sharing method by adjusting the droop voltage slope is proposed, in order to increase the accuracy of the reactive power sharing. The mismatch of line impedances lead to mismatch of voltage drop across the line is compensated by adjusting the droop voltage slope. The droop voltage slope is adjusted to adaptive with the change of load, the results of proposed method is more accurate reactive power sharing than conventional methods. The feasibility and effectiveness of the proposed strategy are evidenced by the simulation results.
