A SURVEY ON STABILITY CONTROL IN FLEXIBLE AC TRANSMISSION SYSTEMS

This paper presents a review on the current development of stability control in flexible AC transmission systems from three aspects: mathematical models, installation locations and control strategies. Mathematical models of FACTS devices are described according to their working principles. Various methods of selecting GACTS'installation locations are discussed, and two novel tools are proposed Normal Form technique and sensitivity analysis using EEAC theory. Applications of nonlinear control and artificial intelligence in FACTS controller design are also expounded. It is pointed out that the key of FACTS synthetic intelligent controller design is the quantitative analysis technique of power system stability.
