【Abstract】 Based on the characteristics of the rural power grid,this paper establishes a mathematical model for reactive power optimization,which has comprehensively taken into consideration the yearly network loss,the voltage quality and the investment in compensation equipment.Adaptive GA is applied to improving 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 convergence speed and the precision. Examples demonstrated in this paper prove that the optimization effect of the improved algorithm is superior to that of the traditional GA.更多还原
