摘要
本文对多目标最优潮流算法进行了研究,通过运用改进粒子群算法对考虑发电费用和有功网损的多目标最优潮流进行了计算。首先运用模糊集理论对多目标函数进行了处理,使其转化成单目标问题;其次对粒子群算法进行了改进,通过对加权系数和粒子位置变量的改变,避免粒子群在寻优过程中陷入局部最优;运用C均值聚类算法对解集作了聚类处理,使解满足均一化的要求。通过对IEEE系统的测试,证明了本文算法的正确性。
The multiobjective optimimal power flow algorithm is researched in this paper. Using the improved partical swarm optimization algorthim to calculate power flow considering the cost and network loss. The fuzzy set theory is used in multiobjective function processing to make it a single objective. And the partical swarm optimization algorthim is improved through adjusting and particle position variable to avoid being into a local optimal. Using C means clustering algorithm for set esterase processing, and making the solution more satisfying the requirements of the homogenization. The correctness of the algorithm researched in this paper is proved through the IEEE system test.
