Abstract
In this paper, a comprehensive analysis on bifurcations of a model power system has been performed. Power system consists of synchronous generator, dynamic load, infinite bus and the network in between these elements. Input mechanical power of synchronous generator, reactive power demand at load bus, and reference voltage of excitation system are considered as bifurcation parameters. The dynamics are analyzed under three different dimensions, 6 dimensional dynamics, 7 dimensional dynamics and 9 dimensional dynamics, which has not been analyzed in previous studies. Dynamic and static bifurcations are studied, and as a result of cascading period doubling bifurcations in periodic orbits emerged from Hopf bifurcations, chaotic observations in system behavior is confirmed.
