Available Transfer Capability Enhancement with FACTS: Perspective of Performance Comparison

Static Var Compensator (SVC) and Thyristor Controlled Series Compensator (TCSC) models were incorporated into Newton Raphson power flow equations for enhancement of available transfer capability (ATC) of a deregulated power network in this study. Bus voltage profile improvement and real power loss minimization were considered as part of objectives and were investigated during ATC enhancement. The performance of the duo based on these objectives were analytically compared. IEEE 30 bus network system was used for these comparative analyses and the implementation was done in Matlab environment. Real power loss minimization of up to 0.06 MW and voltage improvement of bus 21 to 30 were achieved with SVC, while ATC enhancement of up to 14% were recorded for both devices. ATC values, bus voltage magnitude profile and transmission line real power losses suggested an advantage of SVC over TCSC for ATC enhancement deployment.
