Abstract : As the demand on power system increases the transmission system is forced to operate beyond its transfer capability resulting in congestion. It may cause cascaded outages, voltage instability etc which in turn affect the system security and reliability. So congestion management becomes crucial for the efficient power transfer in the power system. This paper deals with a method for congestion management by real power flow control using TCSC. The power injection required to relieve congestion is calculated based on DC power flow equations. Optimal location of TCSC is obtained by sensitivity based approach. A control algorithm is developed for congestion management by real power flow control using reactance compensation and is tested on a 5 bus system.
