Improvement of power systems damping using genetic algorithms aided proportional plus derivative output feedback for TCSC

This paper develops a proportional plus derivative (PD) control scheme for a thyristor controlled series compensator (TCSC) to reinforce power system damping performance. This PD control scheme is aided by the use of genetic algorithms (GAs). The effectiveness of the proposed method is demonstrated through computer simulation using a multi-machine power system associated with a single TCSC. Results show that the proposed PD controller can achieve good damping performance
