• Small signal stability
• Parameter sensitivities
• Equilibrium points
• Hopf bifurcation
• Selective modal analysis

This paper proposes to use the trajectory sensitivity theory to assess the influence of the system's parameters on the power system equilibrium. The proposed parameter sensitivity approach provides complementary information to that given by selective modal analysis which can help determine how the state variables linked with the critical eigenvalues are affected by the system's parameters. The parameter sensitivities also provide a way of judging how the system's parameters affect the oscillatory behavior of a power system. The proposed method is demonstrated on the 3-machine, 9-bus WSCC system and a 46-machine, 190-bus equivalent Mexican system.
