Comparison of Different Optimal Placement Models of FACTS Devices in Power System Networks on a Limited Budget

Abstract

The problem of transmission network congestion or overloading poses a serious challenge to most power utilities around the world. One solution to this problem is the use of FACTS devices. This paper presents an empirical comparison of different optimal placement models of FACTS devices in a power system network with the objective to maximize the system loadability (SL). The three configuration are considered in this comparison. In the first case only TCPST is considered, while in the second case only TCSC is considered and in the third one a combination of several devices is considered. The results show that the first and the third configuration performs better economically and in terms of system losses.
