Rapid growth in deregulation of electric power system networks across the world results in transmission congestion. Transmission congestion management is important for secured and satisfactory operation of power system networks particularly under the deregulated environment. Flexible Alternating Current transmission system (FACTS) devices can be used for changing the flow pattern through the lines and thereby managing congestion is possible. In this work, shunt connected static Var compensators (SVC) devices are used for managing transmission congestion in a power system. The size and location of the SVC device affects the performance of congestion management. For optimizing the transmission congestion management, the site and size of the SVC devices are to be decided by an optimization algorithm. Whale optimization algorithm (WOA) is employed here for the optimization task. The algorithm is a recent development and involves less parameters to be tuned. The strength of the algorithm is tested on the standard IEEE 30 bus system under three different operating conditions and the results obtained are compared against the results of two other algorithms and found to be encouraging.
