| Abstract: | In order to solve the problems of particle swarm algorithm used in reactive power optimization for power system, an improved particle swarms cooperative optimization algorithm is proposed. According to the characteristics of reactive power optimization for power system including nonlinearity, discontinuity, wide range, increase of voltage level and many control variables of reactive power optimization, the author establishes the mathematical model of reactive power optimization based on particle swarms cooperative optimization algorithm, which is applied in reactive power optimization. The result of the example shows that this algorithm is able to improve the partial convergence of particle swarms algorithm, shorten search time and enhance accuracy. |
