Optimal location of Unified Power Flow Controller (UPFC) to control active power flows and congestion Management in a transmission lines by using Fuzzy Based Technique
The objective of this paper which concentrates on the application of Flexible Alternative Current Transmission System (FACTS) controllers as a solution to the problem of congestion(transmission system to operate beyond transfer limits) management.In the emerging electric power market, congestion management becomes extremely important and it can impose barrier to electric power trading. For thisFACTS also an alternative to reduce the flows in heavily loaded lines, resulting low system loss, improved stability of the network, reduced cost of production and fulfilled contractual requirement by controlling the power flow in the network.A line utilization factor (LUF) is used to determine the level of congestion in a transmission line. In this paper a Fuzzy Based Technique is proposed in determining the optimal location of unified power flow controller (UPFC) to control active power flows and reduction of congestion in a transmission line. This method is tested on IEEE 14bus system using MATLAB Simulation.
