Robust excitation control of multi-machine multi-load power systems using Hamiltonian function method

Abstract

Using an energy-based Hamiltonian function method, this paper investigates the robust excitation control of multi-machine multi-load power systems described by a set of uncertain differential algebraic equations. First, we complete the dissipative Hamiltonian realization of the power system and adjust its operating point by the means of pre-feedback control. Then, based on the obtained Hamiltonian realization, we discuss the robust excitation control of the power system and put forward an H_{\infty } excitation control strategy. Simulation results demonstrate the effectiveness of the control scheme.
