In a restructured electricity market environment, when the producers and consumers of electric energy desire to produce and consume in amounts that would cause the transmission network to operate at or beyond one or more transfer limits, the system is said to be congested. The congestion in the system cannot be allowed to persist for a long time, as it can cause sudden rise in the electricity price and threaten system security and reliability. Congestion management (CM) is one of the most important challenging tasks of the Independent System Operator (ISO) in the deregulated environment. In this article, generators' rescheduling-based CM approach to manage transmission line congestion considering voltage stability limit has been presented for pool-based electricity market model. The results have also been obtained without taking loadability limit for comparison. The results have been obtained for IEEE 24 bus test system.
