Congestion Management in Transmission lines considering Demand Response and FACTS devices

S.Nandini, P.Suganya, Mrs. K. Muthu Lakshmi

In a deregulated electricity market, it may always not be possible to dispatch all of the contracted power transactions due to congestion of the transmission corridors. This paper presents a transmission lines congestion management in a restructured market environment using a combination of demand response and Thyristor controlled series compensators (TCSCs). The overall objective of FACTS device placement can be either to minimize the total congestion rent or to maximize the social welfare. The main motivation of the work is to carry out the contingency selection by calculating the Generation shift factor (GSF) for generator outage and to implement the demand response and Flexible AC Transmission Systems (FACTS) in managing the transmission congestion. The effectiveness of the method has been tested and validated with TCSC and SVC in IEEE 30 bus test system.
