Distributed generation (DG) has been largely used in distribution network in recent years, which brings more security, reliability, and economy, but some bad effects to the distribution network. In this study, recovering more loads, less switching actions and distribution network power loss are considered to establish the mathematical model of fault recovery in distribution network with DG. The particle swarm optimisation algorithm is used to solve the problem, and the fault recovery strategy is obtained. Besides, the impact of DG location on the fault recovery of distribution network is studied, and the simulation results show that when the DG is located dispersedly in the downstream of the distribution network, the distribution network recovery is in good condition. The results of this study provide a reference for the DG configuration of the distribution network.
