Optimal Location of FACTS Devices for Congestion Management in Deregulated Power Systems

Abstract

In the emerging deregulated electric power market, congestion management becomes extremely important and it can impose barrier to electric power trading. There are t w o types of congestion management methodologies to relieve congestion in transmission lines. One is non-cost free methods and another is cost-free methods, among them later method relieves the congestion technically whereas the former is related more with the economics. In this paper congestion is relieved using cost free method. Among the various cost free methods, use of FACTS devices method is considered in this paper. The optimal location of TCSC and UPFC to relieve congestion in the network is proposed. In congestion management, the objective function is nonlinear hence for solving this function genetic algorithm (GA) technique is used. The above method is tested on IEEE 57-bus system and it can be readily extended to any practical systems.

Congestion Management in Power System—A Review

“…Literature [27] discussed an improved performance by using FACTS devices and optimal location of TCSC and UPFC for congestion management. In this paper, author implemented a nonlinear objective function which can be solved by genetic algorithm for optimal generation schedule for social welfare maximizing.…”

Optimal Congestion Management with FACTS Devices for Optimal Power Dispatch in the Deregulated Electricity Market

“…Whereas the combination of both series and shunt devices like UPFC allows for continuous control of all these factors. Some work has been done by the authors to reduce congestion by employing UPFC [29][30][31]. From the literature [24][25][26][27][28][29][30][31], which utilized different FACTS devices, it is observed that the UPFC FACTS device plays a vital role in controlling congestion.…”

“…The successive linear programming for solution of the security constraints economic dispatch is proposed in [11]. In [12] Optimal location of UPFC and TCSC is proposed to relieve the congestion in power system network. The genetic algorithm in conjunction with fuzzy logic is used to find the location of FACTS devices in power system as discussed in [13].…”
