Coordinated control of power system stabilizer and FACTS devices for dynamic performance enhancement — State of art

There are two types of oscillation damping controller in power system which are power system stabilizer (PSS) and flexible ac transmission systems (FACTS). Numerous works have been carried out on the damping of power system low frequency oscillations. This paper addresses an extensive literature review on coordination problem in single-machine and multi-machine power system. It also reviews various types of FACTS controllers. Various methods are proposed in order to enhance the dynamic performance of a power system for coordinated control between FACTS and PSS controller in power system models.
