Algorithm for Time-varying Reactive Power Optimization

SHEN Mao-ya1,DING Xiao-qun1,WANG Zhong-da1,WANG Kuan1,CHEN Guang-yu2,FENG Lei3(1.College of Electrical Engineering,Hohai University,Nanjing 210098,China;2.Nanjing Hohai Electric Software CO.,LTD.,Nanjing 210098,China;3.Sishui Power Company,Sishui 273200,China)  
A new algorithm is proposed in the paper for time-varying reactive power optimization according to the load variation.Considering the characteristics of load curve and the act times of devices,an intellectualized method using genetic algorithm for dividing load curve is presented.The proposed method can acquire the optimal control mode of the whole power system by using the particle swarm optimization method which has a mechanism of immune information management and an adaptive factor with an ability of adjusting momentum coefficient automatically.Results from IEEE-30 system indicate that the proposed method can effectively reduce the act times of compensatory devices and transformer taps as well as the power loss of the system.
