1. IntroductionA flexible DC distribution system can efficiently and flexibly connect DC loads and distributed power sources in the distribution network. It solves the problems of the short-circuit capacity and power supply radius of an AC distribution network while improving power supply efficiency and power quality [,]. Early research on DC distribution grids focused on low-voltage DC distribution grids.
