A refined hybrid genetic algorithm for distribution network reconfiguration

This paper proposes an improved solution for distribution network reconfiguration based on a refined hybrid genetic algorithm. In the algorithm, the "the integer permutation" encoding is adopted with each integer representing one controllable switch. A decoder is designed to decide the final network configuration corresponding every chromosome. A local search operator is combined with the genetic algorithm which improves the local optimal capability of the algorithm. The computational results on a tested system demonstrate the algorithm is feasible and efficient.
