Abstract
In this article a new nonlinear decentralized disturbance attenuation excitation control for multimachine power systems is proposed based on recursive design without linearization treatment. The proposed controller improves system robustness to dynamic uncertainties and also attenuates bounded exogenous disturbances on the system in the sense of L2-gain [1]. Computer test results on a six-machine system show clearly that the proposed excitation control strategy can enhance transient stability of power systems more effectively than other excitation controllers.
