Congestion management is one of the most important issues for secure and reliable system operations in deregulated electricity market. In this paper, an efficient method is proposed for transmission line over load alleviation in deregulated power system using FACTS devices and Load Shedding. For secure operation of power system, the network loading has to be maintained within specified limits. Transmission line congestion initiates the cascading outages which force the system to collapse. Accurate prediction and alleviation of line overloads are the suitable corrective action to avoid network collapse. In this paper an attempt is made to explore the use of FACTS devices and Load Shedding for relieving congestion by Extended Quadratic Interior Point (EQIP) based OPF. The effectiveness of the proposed algorithm has been analyzed on IEEE 57 bus system.
