Abstract

The increasingly serious energy crisis and environmental pollution problems promote the large-scale application of microgrids (MGs) and electric vehicles (EVs). As the main carrier of MGs and EVs, distribution network is gradually presenting multi-source and active characteristics. A multi-level service restoration strategy of distribution network with MGs and EVs is proposed in this paper, which makes full use of the power supply capability from MGs and EVs. An optimal power flow (OPF) model is constructed to minimize the network loss after the service restoration. The proposed service restoration method is verified by applying a single fault on a modified IEEE distribution system with three-feeder and eighteen nodes containing MGs and EVs, which shows its feasibility and effectiveness.
