- Abstract:

The exeilation conlrol of power systems under generator tripping emergeney measurement is invesli-gated. First, a switched dynamie model for a typieal lEEE three-machine multi-area power system is devel.oped. Then , the switched power system is transformed to an equivalent switched dissipative Hamiltonian sys.tem via pre-feedback control. A state feedbaek switching eontroller is constructed based on the dissipativeHamiltonian realization. Using the Hamiltonian funetions of the subsysems as multiple Lyapunov funetions, itis shown that the closed-loop system is asymptotically stable under arbitrary switching path. Simulation resultsdemonstrate that the proposed eontroller ean elfeclively improve the transient stability of the power system.
