Abstract: This paper proposes a formulation to provide necessary and sufficient conditions for robust stability of a family of matrices modeling linearized power system dynamics. A construction for transforming variations in operating point into a polytope of matrices for the linearized system models is derived. Sufficient conditions to establish robust stability or instability of a polytope are developed. Finally, an iterative "branch and bound" technique is described that combines these tests to provide a necessary and sufficient test for robust stability of the matrix polytope.
