Abstract

The phenomenon of Hopf bifurcation is observed in several engineering and non-engineering domains which use both linear and nonlinear dynamic models. One parameter and two parameter variations of set of Differential Algebraic Equations of Kundur two area system was explored in this manuscript assisted with eight different cases to have detailed insight into Hopf bifurcation by modelling the load buses with industrial loads. The effect of PSS on improving the damping ratio and increase in the maximum loading at the industrial load buses was showcased by taking Hopf bifurcation as a tool for assessing the same by increasing the generation.

Keywords: Damping ratios, Hopf bifurcation point, Inter-area mode, Power System Stabilizer.
