Abstract :
This paper investigates the existence of multiple branches of the bifurcation surface of a power system. At points where such branches intersect we identify singular points of the bifurcation surface. Analyzing two simple power systems, we identify a cusp, a "pure fold" and a codimension 3 bifurcation.
