A Synchrophasor-Based Scheme For Power System Voltage Stability Protection And Control
This paper proposes a synchrophasor-based scheme forpower system voltage stability protection and control. In
order to reduce the risk of voltage collapse, the proposed method uses real-time and synchronized data from wide area
measurement system (WAMS) to monitor and control power system voltage stability. Since voltage stability is affected by
the load characteristics, the composite ZIP load model is used in this study. An extensive simulation studies on the IEEE 9-
bus system is carried out to demonstrate the effectiveness of the proposed method.
