A New Droop Coefficient Design Method for Accurate Power-Sharing in VSC-MTDC Systems

A New Droop Coefficient Design Method for Accurate Power-Sharing in VSC-MTDC Systems

This paper proposes a new droop coefficient design method with the aim of improving the power-sharing accuracy among the converters in a multi-terminal dc (MTDC) system. The proposed droop coefficient design method works by adjusting the droop coefficient and can realize an arbitrary power-sharing r...
