Minimization of losses and maintaining voltage stability are the two fundamental requirements of power system operation. Flexible AC transmission systems (FACTS) devices like thyristor-controlled series compensator (TCSC) and unified power flow controller (UPFC) are employed for this purpose. While they have their own advantages, using their combination to better the power system performance is an important issue. Locating these devices in power system appropriately is a challenging task. Many optimization techniques have been employed for this purpose. Social group optimization (SGO) is a recent advanced technique which promises better accuracy. This paper employs the technique to determine the location of in the transmission line. Two types of FACTS devices are considered. The impact of using a combination of TCSC and UPFC is examined in minimizing the power loss and maintaining the voltage stability of the system. Simulations are performed on standards IEEE-6, IEEE-14, and IEEE-57 bus systems to establish the efficacy of the SGO technique.
