  • Abstract
    Using an energy-based method, this paper investigates the L 2 disturbance attenuation excitation control of multimachine power system connected with constant power loads. First, a general result is presented for the L 2 disturbance attenuation control of nonlinear differential algebraic systems with dissipative Hamiltonian realization. Then, pre-feedback is employed to transform the power system into a dissipative Hamiltonian form. Based on this, a decentralized L 2 excitation control scheme is proposed to improve the transient stability of the system. Simulation results demonstrate the effectiveness of the controller.
