Research on Reactive Power Optimization of Distribution Network Based on Improved PSO
In this paper,we establish the objective function and constraint condition of reactive power optimization,and take the static voltage stability constraint into account.The improved particle swarm algorithm is used to opti-mize the reactive power of the distribution network system,and verify the effectiveness of the method through the ex-amples of IEEE33 node system.According to the research,the reactive power optimization of the power system is ef-fective,and the economy and power quality of the optimized system are improved.
