Mz. Elsadek et al., CRITERIA FOR DETECTION OF STEADY-STATE VOLTAGE STABILITY OF POWER-SYSTEMS, Electric machines and power systems, 25(8), 1997, pp. 851-864
The paper presents three different criteria for detection of steady-st
ate voltage instability, for small and large power systems. The formul
ation of one of these criteria is developed here. The application of t
he other two criteria are extended to include large power systems stud
ies with any load-voltage characteristics through a certain suggested
technique. Validation of these criteria is proved and the specificatio
ns of each of them are highlighted.
