The existence of dynamic bifurcations and chaos has been shown by some of the researchers in simple power system networks. This work first demonstrates, through numerical simulation, the existence of various types of dynamic bifurcations in two sample power systems. The presence of torus and limit point of periodic orbits has been observed for the first time in a power system model. Further study has been performed to damp out the Hopf bifurcation using Flexible AC Transmission System (FACTS) devices such as controllable series capacitors (CSCs), controllable phase angle regulators (PARs), and static VAR compensators (SVCs). The participation of states for the critical mode to undergo Hopf bifurcation has been used to select appropriate input to these control elements
