Abstract
Power system is a typical energy system Because Hamiltonian approaches are closely related to the energy of the physical system they have been widely researched in recent years The realization of the Hamiltonian structure of the nonlinear dynamic system is the basis for the application of the Hamiltonian methods However there have been no systematically investigations on the Hamiltonian realization for different power system dynamic models so far This paper researches the Hamiltonian realization in power systems dynamics Starting from the widely used power system dynamic models the paper reveals the intrinsic Hamiltonian structure of the nonlinear power system dynamics and also proposes approaches to formulate the power system Hamiltonian structure Furthermore this paper shows the application of the Hamiltonian structure of the power system dynamics to design nonsmooth controller considering the nonlinear ceiling effects from the real physical limits The general procedure to design controllers via the Hamiltonian structure is also summarized in the paper The controller design based on the Hamiltonian structure is a completely nonlinear method and there is no linearization during the controller design process Thus the nonlinear characteristics of the dynamic system are completely kept and fully utilizedSupported in part by the National Natural Science Foundation of China Grant Nos 50707009 and 50525721 in part by Program for Changjiang Scholars and Innovative Research Team in University under IRT0515 and in part by Ministry of Education of China Grant No 20070079014
