Optimal power distribution system reconfiguration using genetic algorithm

In this paper, a methodology to find the optimal topology of an electric distribution network is presented. To find the spanning tree visiting all the nodes, the study is based on the optimization of a problem using two objective functions: the implantation cost and the active losses in the network lines taking into account a set of economic and functional constraints. The proposed method, for solving this problem, is based on the Genetic Algorithm (G.A) in order for finding the spanning trees visiting all the nodes. The load-flow problem is used to determinate the active losses in the network. The application of the optimization algorithm is executed on a test network included 10 nodes and 19 branches.
