A distributed service restoration method in active distribution network based on the contraction of frontiers

A distributed service restoration method in active distribution network with distributed generators(DG) interconnected is proposed in this paper. According to local topology, switches are divided intogroups to share local measurements. The restoration process is accomplished by the contraction of frontiers. The frontiers are the decision makers of network reconfiguration based on local communication and they will contract step by step until they meet together in a group. During contraction, the load transfer path and islanding separation will be determined. A simulation case of 10kV distribution network with DGs is studied and the whole process of service restoration is analyzed based on DIgSILENT software.
