Research on Fault Self-Healing Method of Distribution Network Based on SOP and Distributed Protection

Under the background of ‘double carbon’, large-scale distributed power supply is added, and the operation mode is becoming more and more complex, which greatly increases the difficulty of self-healing control. Because SOP has the ability to implement power flow control, according to the distributed power supply and SOP access distribution network as the research background, the distributed protection of a new distribution network with SOP is studied, and the fault isolation and self-healing scheme based on multi-terminal information is given. Combined with the 10kV distribution network, the application analysis of the self-healing scheme is carried out. The results show that the scheme can effectively realize the fault self-healing of the distribution network.
