Transmission Congestion Management by Using Series Facts Devices and Changing Participation Factors Of Generators

Abstract: The deregulated power system is quite popular in now a days. The increased power demand has forced the power system to operate very closer to its stability limits. So transmission congestion and voltage instability problems are arise in the power system. Due to the congestion in the network, not always possible to transmit the all contracted power. Congestion management is a tough task in deregulated power system. In this paper two different methodologies were used to manage the congestion in the network. The first methodology is congestion managed using series FACTS device. This method is tested on modified IEEE 5 bus system. The second method is congestion management by changing participation factors of generators. This method is tested on modified IEEE 9 bus system.
