Reconfigueation Distribution Networks Using the Simultaneously Locating of DG and Sectionalizaing Switches to Reduce losses and improve Reliability by the PSO Algorithm

This paper presents a methodology for Placement of sectionalizing switches and distributed generation sources in distribution networks. The multiobjective considerations are handled using a fuzzy approach. The primary objective is a reliable improvement and reducing losses with consideration of economic aspects. Thus, the objectives are defined as a reliable improvement and losses reduction and minimization of the cost of sectionalizing switches and distributed generation sources. A fuzzy membership function is defined for each term in the objective function according to the relevant conditions. Some considerations incorporated in the proposed model are relocation of existing switches and operating constraints on distribution networks and distributed generation (DG) sources during post-fault service restoration. The particle swarm optimization (PSO) algorithm is adopted to solve the fuzzy multi-objective problem efficiently. The performance of the proposed approach is assessed and illustrated by various case studies on a test distribution system and also a real distribution network
