Voltage Stability Analysis of Smart Grid and Application of FACTS Controller: A Review

technology based voltage collapse detection and control interconnected power systems always operate close to stability limits. Increased penetrations of renewable resources have made the situation worst. A small disturbance to these stretched stability limits may lead to voltage collapse. Thus it is indeed important to develop understanding of the phenomenon through reviewing various case studies in literature. This paper explore the initial review on understanding the voltage collapse phenomena, identification of weak nodes, Synchrophasor.
