Abstract:Flexible multi-state switch is a kind of power electronic equipment that replaces the traditional contact switch. It can satisfy the custom power demand such as smart distributed power distribution network as well as high reliability of power supply. The mathematical model and working principle of flexible multi-state switch for flexible interconnection of distribution network are analyzed in detail, and the control method of the flexible interconnection of dual-end distribution network is put forward. The flexible interconnection of two terminal distribution network is simulated in different voltage grades, power grid frequencies and voltage phase angles. The simulation results verify the feasibility and superiority of flexible multi-state switch.
