Optimal Configuration of Capacitors in Distribution Network Based on Niche Genetic Algorithm

Based on GA, this paper introduces niche that is a concept of biology, improves the coding method and genetic operators, and then forms the Niche genetic algorithm that can be used in the optimal configuration of capacitors in distribution network. This algorithm changes individual adaptive value with sharing degree, accelerates to eliminate individual which have low adaptive value, increases the average adaptive value of every generation, and achieves the goal of reducing iterative times. Test results on the example indicate the feasibility of the proposed algorithm.
