Abstract :
This paper reports on tests validating a fast voltage stability analysis method, envisaged for operational planning and real-time applications. The simulation method relies on quasi-steady-state approximation, replacing the transient dynamics with equilibrium equations and focusing on the long-term dynamics. Various comparisons have been performed with full time simulation, on the 514-bus Hydro-Quebec system. The accuracy is equivalent while the new method is up to 3 orders of magnitude faster
