Abstract
Formulas for the sensitivity of the Hopf loading margin with respect to any power system parameter are presented. These first-order sensitivities determine an optimum direction in parameter space for changing parameters to increase the loading margin. The Hopf bifurcation sensitivities of a simple power system with a voltage regulator and a dynamic load model are computed. Parameter sensitivities of the Hopf and saddle node bifurcations are compared. An idea for eliminating some Hopf bifurcations is presented
