To this end, we carry out a local stability analysis of the third-order model which entails the classical power-swing equations and the voltage dynamics. We provide necessary and sufficient stability conditions and investigate different routes to instability. For the special case of a two-bus system, we analytically derive a global stability map.en1054-150020183American Institute of PhysicsNatural Resources, Energy and EnvironmentMathematicsJournal Article10.1063/1.5002889Other
