Excitation control is one of the most effective means to improve the dynamic performance of power systems. This paper investigate the switched excitation control of power systems with generator tripping operation under emergency. First, we discuss the dynamics of the generators under different operating conditions and put forward a switched power system model. Then, the switched dynamic model is transformed...
The dynamic output feedback L2 disturbance attenuation control of linear parameter-varying (LPV) singular systems is investigated in this paper. Based on a general Lyapunov inequality, we first provide a condition that guarantees the admissability and the L2 gain performance of LPV singular systems. Then, the existence of dynamic output feedback L2 disturbance attenuation controller of the system...
Using the Hamiltonian function method, we investigate the excitation control of power systems presented by nonlinear differential algebraic equations. First, a novel Hamiltonian realization structure for nonlinear differential algebraic systems is applied to the power system. Then we propose a decentralized nonlinear excitation control scheme and analyze the stability of the closed loop system. This...
