Dissipative Hamiltonian realization and energy-based L2-disturbance attenuation control of multimachine power systems

The note considers the L₂-disturbance attenuation of multimachine power systems via dissipative pseudo-Hamiltonian realization of the systems. First, the note expresses multimachine systems as a dissipative Hamiltonian system. Then, the note investigates the energy-based control design of L₂-disturbance attenuation of multimachine power systems and proposes a decentralized simple control strategy. Simulations on a six-machine system show that the achieved L₂-disturbance attenuation control strategy is very effective.
