Reconfiguration of Radial Distribution Networks by Applying a Multi-objective Technique

In this paper, the reconfiguration of distribution networks in order to optimize several aspects of its operation is presented. The proposed methodology based on genetic algorithms finds the optimal reconfiguration for networks which have a radial topology, taking in consideration the expected occurrence of voltage sags reduction and also the real power losses. The developed functions of the genetic algorithm are described, and case studies are presented for the IEEE 33-bus test network and the IEEE 118-bus test system demonstrating the effectiveness of the implemented methodology.
