Abstract :
A robust control strategy is proposed to control UPFC in different operating conditions. PI regulators used for UPFC suffer from the inadequacies of providing suitable control for transient stability enhancement over a wide range of system operating conditions. In this paper an optimization method based on particle-swarm optimization (PSO) algorithm is presented to optimize the parameters of the PI controller of UPFC in order to enhance the power system transient stability. This scheme dispenses the gain dependency of the proportional or integral gains and generates independent control actions. The effectiveness of the proposed method is demonstrated using simulations of a multi-machine power system.
