Switching control strategy for power systems with losses

Energy functions were developed for assessment of stability of multimachine power systems. This paper develops a switching control strategy for suppression of oscillations of power systems. This strategy is based on energy function using shunt and series compensators for lossy multimachine power systems. The switching control design is on the basis of maximizing the convergence rate of an energy function. Fast multimode damping and the monotonic convergence of the energy is demonstrated on a three machine power system.
