Recent advances of research on power supply restoration of distribution network under extreme events

Abstract

In recent years, the probability of large-scale power outage in distribution network caused by extreme events continues to increase, which poses a serious threat to people's life, market economy and social stability. With the continuous development of renewable energy, more and more distributed power sources are connected to the distribution network, which significantly improves the power supply reliability of the distribution network and also provides a way to ensure the continuous power supply of key facilities in extreme events. Based on the analysis of the severe damage caused by extreme events to distribution network, this paper summarizes the current power supply recovery ideas, power supply recovery model and power supply recovery algorithm of distribution network under extreme events, and finally prospects the development trend of power supply recovery problem of distribution network under extreme events.
