Atc evaluation and maximization by optimal sizing & location of TCSC using grey wolf optimization

Abstract

Deregulation of power system provided the consumers more economical rates of electricity, but this also resulted in congestion of the power system due to participation of private utilities and increase in population. To remove congestion in the power system cost free and non cost free methods are used. Incorporation of FACTS devices, which is one of the cost free method, has proven a great efficiency in reducing system congestion. This paper demonstrates the novel method of incorporating FACTS device (TCSC) in the standard IEEE 30 Bus system with the help of Grey Wolf Optimisation which not only finds the location of device but also tunes the device so as to minimise power system losses and on the other hand increases the Available transfer capability (ATC) of the system above mentioned, by using ACPTDF, as the sensitivity factor. The utility of GWO is illustrated in this paper on standard IEEE 30 bus system and is demonstrated with the help of suitable table and figures.
