Abstract 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.
