Series FACTS Devices such as TCSC, with its ability to directly control the power flow can be very effective to improve the operation of transmission network. In this paper, a corrective solution for congestion management by using TCSC has been reviewed. A harmony search algorithm for optimal utilization of this device is proposed for congestion management with the increasing social welfare while usage cost associated with the TCSC is not taken into account. The simulation results were successfully tested on a 5 bus system. Analyzing the result with and without TCSC confirms that this device is appropriate for a long time congestion management
