Abstract

Abstract: The coordinated operation of multiple thyristor controlled series compensator(TCSC) can improve the capability of the power transmission. However, the mutual effects of TCSCs may decrease the transient stability. In this paper, a new adaptive control scheme is designed through dynamic adaptive adjustment of the parameters of multiple TCSCs to avoid the negative interactions of TCSCs. By using energy function to evaluate the stability of the TCSC, a differential observer adaptive TCSC controller is then designed, which uses expert controller and neural network to adaptively adjust the proportion integral differential(PID) parameters. The effectiveness of the proposed control scheme was demonstrated through simulating a two-area and four-machine power system. A comparison of the proposed controller, the adaptive FACTS controller and the BP-PI controller (back propagation-proportional integral controller) was conducted, which shows that the adaptive FACTS controller can improve the transient stability of power system.
