Abstract

Motivated by transient stability analysis of power systems, a framework for study of Lyapunov stability of equilibria in differential/ algebraic (DA) systems is presented. Following a basic result on existence and uniqueness of solutions, it is easy to state general stability results. Several useful stability criteria for special DA structures are derived. One result for a Hamiltonian type structure is applied to the study of undamped power systems.
