Abstract: Over the last two decades, instability problem in power systems have become one of the most important concerns in the power industry which lead to blackouts. So, it is very important to have high efficiency, maximum reliability, and security in design and operation of power system. Recent development of power electronics introduces the use of flexible ac transmission system (FACTS) controllers in power systems. FACTS controllers are capable of controlling the network condition in a very fast manner and this feature of FACTS can be exploited to improve the stability of a power system. Thyristor controlled series compensator (TCSC) is one of the FACTS devices used for maintaining and enhancing the power system security. This paper gives a review about different methods used for enhancement of power system security.

Keywords: TCSC (thyristor controlled series compensator), FACTS, Sensitivity index.
