Abstract :
This paper aims at capturing the voltage collapse trajectories beyond the steady state loading limit for power systems immediately following a branch outage. Instantaneous Time Domain Simulations are done with two types of transmission line models: Bergeron Model, and Lumped Parameter Model. The constant power load is modeled as a voltage dependent impedance. The results are compared with the continuation power flow which assesses the steady state loadability of the system.
