Abstract :
A voltage stability security assessment method is developed that can identify (i) each region that experiences voltage collapse and (ii) the equipment outages that cause voltage collapse in each of these regions. The method establishes whether the voltage collapse caused by a contingency is due to clogging voltage instability or loss of control voltage instability. The advantages of the method is that it requires little computation and is comprehensive in attempting to find all regions with voltage collapse problems and all single and double equipment outages that cause voltage collapse in each region
