Abstract: This research paper deals with the congestion of transmission lines in deregulated electricity market and thus, suggesting an optimal power flow framework to solve the problem. In this research paper, a model has been designed that help decongest using re-dispatch method and then calculate the taxes. In order to reduce taxes, it considers the installation of flexible AC transmission systems (FACTS) devices in the transmission network. The optimal location of FACTS devices can be recognised by the bus on which maximum tax is imposed. The IEEE 30-bus system is used to simulate the market and illustrate the proposed method. The simulation is done in MATLAB. The results show that when SVC is included, the amount of re-dispatched power reduces significantly, resulting in an optimal operating point closer to that dictated by the market settlement. Secondly, the results prove that SVC is a viable option for congestion management, from technical as well as economical points of view.
