FACTS Applications’ in Enhancement of Power system Low Frequency Oscillations: A Review

At the present time, FACTS technology has already been considered to bring a bright prospect for the modem power system. By the flexible and rapid control over the AC transmission parameters and network topology, FACTS can facilitate the power control, enhance the power transfer capacity, decrease line losses and generation costs, and improve the stability and security of the power system. This paper gives a general overview of its need, FACTS technological development and the opportunities FACTS enjoy. The main crux of this paper mainly focuses on the need for evolution of FACTS, its advancement in technology surpassing umpteen obsolete technologies and the opportunities it faces in the present day context. This paper presents a survey of literature on the various methods, algorithms and optimizationmethods applied to solve the low frequency oscillations problems. The purpose of this paper is to present an overview of the FACTS controller, Co-ordination of FACTS controller with PSS on different techniques and optimization methods on published literature from 2000 to the present.
