In recent years, deregulation of the electric industry in the world aims at creating competitive markets to trade electricity. For deregulated transmission networks, one of the major consequences of the nondiscriminatory open-access requirement is a substantial increase of power transfers. Congestion management of deregulated transmission networks is very important to accomplish always nondiscriminative network access. In this paper, the authors propose a congestion management approach by using Thyristor Controlled Series Capacitor (TCSC) in order to maximize transmission margin and minimize transmission loss without changing contracted power under constraints such as thermal, voltage, and stability limits. In the proposed approach, power flow through transmission lines can be flexibly controlled without changing contracted power by determining firing angle of TCSC. In order to check the validity of the proposed congestion management approach, numerical results are shown for 6 bus system model. Simulation results show effectiveness of the proposed congestion management approach by using TCSC, when congestion occurs at a transmission line in the system model.
