Refined genetic algorithm for minimum-loss reconfiguration of electrical distribution network

This paper proposes a model of distribution network reconfiguration (DNRC) to minimize the system power loss. A refined genetic algorithm (GA) is set up, in which some improvements are made on chromosome coding, fitness function and mutation pattern. As a result, premature convergence is avoided. The proposed approach is tested on 16 bus and 33-bus distribution networks. Study results are given in the paper.
