Optimal locating and sizing of TCSC using genetic algorithm for congestion management in deregualted power markets

Abstract

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 corrective solution for congestion management by using TCSC has been reviewed. A novel genetic algorithm for finding the optimal location and size of this device was proposed for congestion management with the aim of increasing social welfare while cost of TCSC was incorporated. The simulation results were successfully tested on IEEE 14-bus system. Analyzing the results with and without FACTS devices confirms that these devices are appropriate for long time congestion management.
