In contemporary power system studies, the optimal location and utilization of FACTS devices are important issues primarily due to their cost-effective option for power delivery system enhancements. Amongst various power electronic devices, the thyristor controlled series capacitor (TCSC) and a static synchronous series compensator (SSSC) device has captured the interest of researchers for its capability of regulating the power flow and minimizing the power losses simultaneously. Since for a cost effective application of FACTS technology a proper selection and placement of these devices is required, the scope of this paper is to propose the device location. The proposed placement approach reduces the congestion under normal and contingency condition in the transmission lines and their comparison. The modified IEEE 14-bus test system is selected to illustrate the feasibility of TCSC and SSSC models using power world simulator software.
