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.
