Abstract :
This paper discusses the implication of a dynamic system model for voltage collapse analysis. Some voltage collapse indices previously proposed in the literature are monitored under a static and a dynamic system model. The results are obtained using the IEEE 118 bus system. The indices behavior and load margin obtained for each model are analyzed
