FACTS devices are considered a powerful tool for enhancing both steady-state and dynamic performance of power systems. It is important to investigate the location for placement of these devices because of their considerable cost and their inverse effects on power systems if they are badly located. Locations of FACTS devices in the power system can be obtained on the basis of static and/or dynamic performance. The intended objective of the FACTS device will have a large impact on the placement of the devices. A location that is the best for one objective may be less suitable for another. This paper presents a new multi-objective placement technique of TCSC based on sensitivity analysis for: maximum relief of network loading (or congestion), power flow control, maximum reduction in active and reactive losses in a particular line, and maximum reduction in active and reactive power loss of a power network. Moreover, OPF with FACTS constraints is used to show the validity of the placement technique to relief network congestions without load curtailment.
