Dynamic Reactive Power Optimization of Sub-periods in Distribution Network With Wind Power
The access of wind farm caused frequent action of reactive compensation equipment in distribution network. This paper presents a new dynamic reactive power optimization method, first segment the wind power curve, and then use integrating dynamic reactive power optimization. In view of using integrating dynamic reactive power optimization directly will cause the dimension disaster and the algorithm hard to convergence, this paper use a new segment method based on pedigree clustering. In view of the traditional particle swarm optimization algorithm converges to the global optimal solution is slow and easy to fall into local optimal solution, this paper uses cloud model to dynamically adjust the weight of particle swarm algorithm. At last, apply the above mentioned algorithm to the improved IEEE 33 distribution network, the simulation results show that the dynamic optimization method which is proposed in this paper reduces the optimization time, and reduces the number of control equipment actions, thus extends the working life of facilities.
