Congestion and overloads in transmission lines always is one of the basic problems in the power system operation. Some of the consequences of this problem in the restructured power system are sudden price increasing in some areas, increase in market power and reduction in the competition in the market. FACTS devices as an efficient, powerful and economical means can have a key role in transmission line congestion management. Locating and parameters setting of the FACTS devices is very important to achieve the desired objectives. In this paper, TCPST has been used in the congestion management. For optimal setting of TCPST and determining the appropriate location for the management and reduction of the transmission lines congestion in the restructured environment, a method based on the locational marginal price (LMP) and optimal power flow (OPF) in combination with TCPST is used. This method is applied on IEEE 14 and 30 bus systems. Simulation results show the effect of TCPST appropriate locating on the reduction of the total restructured power system costs.
