Research On Distribution Service Restoration Considering DGs

In this paper, research on distribution service restoration with distributed generation (DG) is made. Deeply considering the distribution network with DGs, operation of DGs in the event of fault is proposed. Constraint satisfaction problem (CSP) model is applied in the DG islanding after fault. The on-line island recognition and division are realized. The islanding algorithm based on CSP converges rapidly and the result could make the global restoration more convenient. Based on the islanding operation, a multi-agent immune algorithm (MIA) is applied to global service restoration and the MIA model of service restoration is presented. At last, the niche PSO is applied on the multi-objective distribution service restoration model. Calculation example manifests the efficiency and feasibility.
