Flexible Alternating Current Transmission Systems (FACTS) represents a vast development in the area of power system operation and control. As we know that under heavily loaded conditions our power system is at high risks of consequent voltageinstability problem. This paper gives an overview about application of series connected Flexible alternating current transmission system (FACTS) for improvement of power system performance like transfer stability, secure voltage profile and reduce the system losses etc. In this work, Artificial Bee Colony algorithm (ABC) is proposed for enhancing and controlling power flow using Thyristor Controlled Series Compensator (TCSC) for improvement of power system performance. This paper gives details of optimal placement and sizing of TCSC devices based on different evolutionary techniques which is used for minimization of transmission loss, enhancement of stability of power system. In this paper TCSC device is implemented on IEEE 57 and IEEE 118 bus systems using MATLAB platform. The results indicates that the proposed algorithm gives better improvement in system load ability, reduction of transmission loss and installation cost. Hence the proposed algorithm will be useful in optimum utilization of power networks.
