Reactive power optimization of power distribution network based on improved genetic algorithm

In view of the defects of traditional genetic algorithm(GA) applied to reactive power optimization of power system,and based on the characteristics of power distribution network,a mathematical model for reactive power optimization is established,which has comprehensively considered the yearly network loss,the voltage quality and the investment in compensation equipment. Meanwhile,adaptive GA is used to improve the genetic operator and the termination criterion of traditional GA,and then an improved GA for reactive power optimization of distribution network is put forward to enhance the calculation efficiency and the ability of global optimization.Calculation examples show that the optimization effect of the improved algorithm is better than that of the traditional GA.
