| Abstract: | The genetic algorithm has three disadvantages:early maturity,poor ability of local optimization,and slow convergence rate.In order to overcome these problems,some modified methods of reactive power optimization to improve the static voltage stability of power system were proposed.In this paper,fitness function was modified by using simulated annealing theory.Genetic algorithm crossover and mutation strategy were improved by using adaptive algorithm.The tactics of elites to keep and mutation operation used t... |
