Abstract
The paper proposes a hybrid droop control strategy to enhance the stability and increase maximum constant power loads (CPLs) capability of DC microgrids in a realistic scenario. By capturing the detailed model of inner control loops and hybrid droop control and general dc MG topology, a thorough comparative study is conducted between traditional droop control and hybrid droop control. Enhanced control bandwidth and system stability margin are shown to illustrate the advantages of the proposal. CPL penetration is one of the critical consideration of this paper. The hybrid droop control can increase the maximum CPL power capability of the system. Simulation studies are conducted to verify the analysis results and the effectiveness of the method.
