Abstract :
An approach to studying certain types of parametric instabilities in electric power networks that are associated with a Hopf bifurcation is discussed. A particular frequency-domain version of the Hopf bifurcation theorem is used to complete an example of power-system flutter instability. It is shown that the instability encountered therein is a Hopf bifurcation and that it is supercritical. The results of the analysis are verified by computer simulation
