Abstract

                         The existing transmission system are currently facing challenges to enhance  the power transfer capabilities. This is where the Flexible AC Transmission Systems (FACTS) technology comes into effect. With relatively low investment, compared to new transmission or generation facilities, the FACTS technology allows the industries to better utilization of  the existing transmission and generation reserves, while enhancing the power system performance. Moreover, the current trend of deregulated electricity market also favors the FACTS controllers in many ways. FACTS controllers in the deregulated electricity market allow the system to be used in more flexible way with increase in various stability margins. FACTS controllers enhance the static performance viz. congestion management, increased loading, , reduced system loss, economic operation, etc., and dynamic performance viz. increased stability limits, damping of power system oscillation, etc.
