REVEL, Gustavo; ALONSO, Diego M.  and  MOIOLA, Jorge L.. Bifurcation theory applied to the analysis of power systems. Rev. Unión Mat. Argent. [online]. 2008, vol.49, n.1, pp.1-14. ISSN 0041-6932.

In this paper, several nonlinear phenomena found in the study of power system networks are described in the context of bifurcation theory. Toward this end, a widely studied 3-bus power system model is considered. The mechanisms leading to static and dynamic bifurcations of equilibria as well as a cascade of period doubling bifurcations of periodic orbits are investigated. It is shown that the cascade verifies the Feigenbaum's universal theory. Finally, a two parameter bifurcation analysis reveals the presence of a Bogdanov-Takens codimension-two bifurcation acting as an organizing center for the dynamics. In addition, evidence on the existence of a complex global phenomena involving homoclinic orbits and a period doubling cascade is included.

Keywords : nonlinear systems; power systems; voltage collapse; numerical analysis; bifurcations; chaos.
