ABSTRACT: This paper focuses on the performance analysis of FACTS devices namely SVC and TCSC in steady state power flow control. Application of Flexible AC Transmission Systems (FACTS) devices in a power system network is an efficient way for the control and transfer of bulk amount of power for long distances. The performance of SVC and TCSC for reactive power injection, real power flow, power loss and voltage improvement are analyzed. The effective utilization of the existing transmission line for the transfer of bulk power is demonstrated. The performance of FACTS devices during single line contingency is also analysed. The modes of operation of SVC and TCSC with respect to bus voltage and power flows are discussed. The ability of FACTS devices to control power flows with various loading conditions is also demonstrated. SVC and TCSC are modelled using Variable Reactance modelling and are then incorporated into the existing Newton Raphson load flow algorithm. Numerical results on a benchmark 5 bus test system and an IEEE 30 bus test system with incorporation of SVC and TCSC are presented.
