Abstract After a fault occurs in the distribution network, power-loss areas can be restored through superior power sources or nearby distributed generators. Therefore, by constructing a correlation matrix between nodes, it is possible to determine whether loads can be restored. After integrating to the distribution network, soft open point can effectively establish a connection between the power-loss area and superior power sources, making it possible to quickly restore power supply. This paper establishes a real-time power balance model in fault recovery process firstly. By constructing a fault recovery model of distribution network considering the integration of soft open point, the impact mechanism of soft open point on fault recovery is analyzed. Finally, the effectiveness of the proposed method is verified through simulation analysis of the modified IEEE 33 node test system.

Key words： distribution network fault recovery distributed generator soft open point (SOP)
