Effects of SVC and TCSC Control Strategies on Static Voltage Collapse Phenomena

This paper focuses on detailed steady state models with emphsize on control loops of two Flexible AC Transmission System (FACTS) devices¿ namely, Static Var Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC) , to study their effects on voltage collapse phenomena in power systems. Based on results at the point of collapse ` control loops strategies which could increase system loadability or increase loadability margin to collapse point are determined. The IEEE 14 bus test system is used to illustrate the effects of FACTS devices control strategies on voltage collapse phenomena.
