Abstract: The demand of power system continuously increases day by day. So many problems are incurred also, like flow violation in transmission lines, voltage depression in busses, static/dynamic instabilities, voltage collapse and so on. The solution adopted by the maximum unity is the Flexible AC Transmission Systems (FACTS) devices. Most of the problem faces by us are minimized by the FACT devices but how we utilize the power of FACT devices is now a days a matter of concern. Because optimization is needed for control and efficient utilization of FACT devices. Therefore in this paper an analysis based on the previous research is being presented.
