Nonlinear decentralized disturbance attenuation excitation controlvia new recursive design for multi-machine power systems

摘要

In this paper, a new nonlinear decentralized disturbancenattenuation excitation control for multi-machine power systems isnproposed based on recursive design without linearization treatment. Thenproposed controller improves system robustness to dynamic uncertaintiesnand also attenuates bounded exogenous disturbances on the system in thensense of L2-gain. Computer test results on a 6-machine systemnshow clearly that the proposed excitation control strategy can enhancentransient stability of power systems more effectively than othernexcitation controllers
