Static Voltage Stability Margin Enhancement Using SVC and TCSC

, 2014
Reactive power limit of power system is one of the major causes of voltage instability. The only way to save the system from voltage instability is to reduce the reactive power load or add additional reactive power to reaching the point of voltage ...
