CONGESTION MANAGEMENT IN COMPETITIVE POWER MARKET USING TCSC

The Optimum Power Flow (OPF) in an interconnected power system is an imperative procedure with respect to transmission loss and other operating constraints. Deregulation of power industry leads to huge change in the process of operation and control strategy of optimum power flow. Increase in power demand leads to increase in power transaction and for satisfying those demands competition arise among the market players (GENCO’s), which create stress on the power system. Thus leading the system to get congested. In this paper, Thyristor Controlled Series Compensator (TCSC) has been used to relieve congestion using conventional NR method. Allen J. Wood six bus systems have been considered as the test bus system. Simulation results with and without TCSC, before and after compensation has been discussed to analyse the impact of TCSC on the congestion levels of the six bus test system.
