Coordinated Allocation of RCSs and MSs for Resilience Enhancement of Distribution Systems

Network reconfiguration is often considered for fast load restoration to enhance distribution system resilience. For distribution systems equipped with remote-controlled switches (RCSs), the network could be reconfigured more fast. Nevertheless, when there is a manual switch (MS), its closed or open state cannot be changed quickly, and its state in the restoration stage shortly after faults is determined by state in the prevention stage. Given these facts, the coordinated allocation of RCSs and MSs for is considered for resilience enhancement in this paper. To make the allocation of RCSs and MSs more effective, the network configuration of the prevent stage through RCSs and MSs and the fast network configuration of the restoration stage based on RCSs are comprehensively considered. The proposed method is applied on the IEEE 33-bus system and its effectiveness is verified.
