CONGESTION MANAGEMENT USING FACTS DEVICES IN DEREGULATED SYSTEM

N.Samba Siva Rao

Abstract: The deregulated power system offers more benefits to the customers so that it is quite popular in now days. The Increased power demand has forced the power system to operate very closer to its stability limits. This paper presents a new method to mitigate congestion in a deregulated Power system. The Increased power demand has forced the power system to operate very closer to its stability limits. So Transmission congestion, Voltage instability and power loss problems are arise in the power system. These are very serious problems which cause damage to the power system Congestion is a tough task in Deregulated power system. This paper deals with the best location for TCSC using priority list to have minimum total congestion rent and minimum total generation cost .The Simulation results were successfully tested on modified IEEE 9 bus system using Power world simulator 11.0.
