Abstract

Abstract: The integration of distributed energy resources, such as distributed generators (DGs) can lead to serious operational problems including voltage violations and network congestion in distribution networks. Flexible distribution multi-state switch (FDS) is a novel power electronic device to realize flexible connection among feeders with high operational flexibility. FDS can regulate the power flow in a more secure, reliable and rapid manner. In this paper, a unified mathematical model of active distribution networks (ADNs) is established to analyze the operation optimization and self-healing control with FDS integration. Based on the pilot project with FDS in Foshan, Guangdong, this paper introduces the topology of FDS and the fault self-healing control strategy of the distribution network with FDS. The results show that FDS can effectively improve the network voltage profile and enhance the reliability of power supply.

Key words: smart grid, flexible distribution multi-state switch (FDS), self-healing control, operation optimization
