Abstract
The access of wind farm causes frequent action of reactive compensation equipment in distribution network. This paper presents a new method, which first segments the wind power curve and then uses overall dynamic reactive power optimization of all periods.To deal with the problem of dimension curse and convergence problem caused by di-rect overall dynamic reactive power optimization on 24h wind power curve, this paper uses a new segmentation method based on pedigree clustering.To address the problem of traditional particle swarm optimization algorithm which con-verges to global optimal solution slowly and easily falls into local optimal solution, this paper uses cloud model to dy-namically adjust the weights in particle swarm algorithm.At last, the above mentioned algorithm is applied to the im-proved IEEE 33 distribution network.Simulation results show that the proposed dynamic optimization method reduces the optimization time and decreases the action times of control equipment, therefore extends the working life of the fa-cilities.关键词
