However, its random output impacts the power quality and stability of the traditional distribution network significantly, including negative sequence current, voltage drop, and power disturbance. A flexible multi-state switch (FMS) can improve the flexibility and security of distribution network operation. It provides a new technical solution for a series of problems caused by the high proportion of renewable energy access to distributed generation. In this paper, the principle and topology of FMS are briefly described. Aiming for the power quality of the distribution network, the control strategies of FMS in unbalanced current regulation, voltage fluctuation suppression, as well as power flow dispatch among ports and feeders are reviewed. The critical control strategies are analyzed and compared. Furthermore, the prospective FMS applications in intelligent distribution networks with renewable energy are discussed.
