Abstract:

In order to control the power flow distribution of power system more effectively,to further improve the effectiveness of the power system reactive power optimization,and to achieve minimizing system loss,this paper proposes a new model based on PSO algorithm for reactive power optimization of a system with UPFC systems.The active network loss minimum is as an objective function using the power injection model of UPFC for effective control of the power flow distribution.This method is implemented and applied into IEEE-30 system and the calculation results indicate that this method not only reduces the active network loss and increases the voltage stability but also reduces the number of iterations of PSO algorithm.Simulation proves the presented model and algorithm are effective and feasible.
