Social Welfare Maximization by Optimal Locating and Sizing of TCSC for Congestion Management in Deregulated Power Markets

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 genetic algorithm for finding the optimal location and size of this device is proposed for congestion management with the aim of increasing social welfare while cost of TCSC was incorporated. The simulation results were successfully tested on the IEEE 30-bus system. Analyzing the results with and without TCSC confirms that this device is an appropriate for a long time congestion management.
