The Application of Improved Self-adaptive Genetic Algorithm in the Distribution Network Reconfiguration

Abstract

Abstract-This paper proposes a kind of encoding method with the loop switch number as gene and the number of branches of the systematic loop as the length of the chromosome, greatly shortening the length of the chromosome. And this paper also takes a kind of effective means in genetic operation, which is eliminating island and loop circuit, thus greatly decreasing the generation of infeasible solution in the operation to gene and increasing the searching ability and speed of the algorithm. The result indicates that, the combination of adaptive control and genetic algorithm, the adaptive adjusting to the crossover rate and mutational rate accelerate the searching speed of the algorithm, and effectively avoid immature convergence.
