Reconfiguration for Loss Reduction of Distribution Systems Using Selective Particle Swarm Optimization

[ISSN: 2045-7057] www.ijmse.org 16 Abstract— This paper aims to present a new simple algorithm for solving the distribution network reconfiguration (DNR) problem. This algorithm is a simple modification to the binary particle swarm optimization (BPSO) called selective particle swarm optimization (SPSO). The search space for proposed algorithm is a set of branches (switches) which are normally closed or normally opened, this search space may be dissimilar for different dimensions. The process of solving DNR problem is divided to two steps. First, finding search spaces after closing all switches and second, using SPSO to find switches that would be opened. The presented technique is applied to a 33-node system and a 69-node system. The results obtained via SPSO are compared with some previous methods to demonstrate the effectiveness of the proposed algorithm.
