Robust nonlinear control for power system excitation based on dissipative system

With suitable co-ordinate transformation, based on the concept of dissipative system, a new robust nonlinear control strategy via disturbance attenuation for power system excitation is proposed without linearization treatment. The proposed controller improves system robustness to dynamic uncertainties and attenuates disturbances on the system. Computer test results show clearly that the proposed excitation control strategy can enhance transient stability of power system.
