Research on the application of flexible multi-state switch in smart distribution network

Based on the background of smart distribution network, this study aims to realize the flexible switching of smart distribution network. It is proposed to study the application of multi-state flexible switching technology in distribution network from three aspects : distributed power consumption of distribution network, power supply quality and operation state regulation of intelligent distribution network, fault early warning and switching state information feedback of intelligent distribution network. This switching mode has been verified in practice, and the flexible switching mode can stably regulate the load of the distribution network, thus improving the power supply quality of the distribution network.
