Research on reactive power optimization for distribution network based on PSO

According to traits of distribution network and operating economical efficiency, this thesis puts forward a optimal capacitor allocation algorithm in getting the target of the minimum network losses based on PSO. This algorithm is used to establish the optimal capacitor allocation and capacity, and attempt to find the optimal reactive compensation scheme. Simulation case shows that the programruing algorithm presented in this paper is effective and works well in getting the target of distribution network losses. It has better economical efficiency in distribution network operation.
