ABSTRACT: In the paper the simplified criterion of a
steady-state stability of electric power systems (EPS) is justified on the
basis of Lyapunov functions in a quadratic form ensuring necessary and
sufficient conditions of its performance. Upon that, the use of the
node-voltage equations allows reducing study of a steady-state stability of
complex EPS to study of the generator-bus system. The obtained results
facilitate studies of a steady-state stability of the complex systems and have
practical importance.
