Flexible Multi-State Switch Application Scenario Analysis

Along with the rapid development of distribution network load, distributed energy and electric vehicles, the traditional distribution network structure and regulation methods face enormous challenges, such as feeder power imbalance, transformer heavy overload, and difficulty in increasing capacity of urban transmission and distribution. The flexible multi-state switching technology of the distribution network has brought about the possibility of solving the above problems. This paper takes the typical application scenario of flexible interconnection in the distribution network as the starting point, analyzes the different application scenarios applicable to the flexible multi-state switch, and studies the functions of the flexible multi-state switch in different application scenarios. The connection modes of flexible multi-state switches in different application scenarios are described. Finally, the topology of flexible multi-state switches in different application scenarios is analyzed and compared.
