Wide-Area Damping Controller Design for Power System via Dynamic Output Feedback

摘要：

　　An approach for the wide-area damping controller(WADC)design via dynamic output feedback(DOF)to improving the performance of large-scale power systems is presented in this paper and network communication features of wide-area measurement system(WAMS)are taken into account.Firstly,a networked control system model for closed-loop power systems is established according to the linearized reduced-order state space description of the open-loop plant.This model captures signal transmission delay,data packet dropout,and packet disordering in constrained network communication of WAMS by time-varying delays.Then,based on Lyapunov theory and linear matrix inequality(LMI)technology,the design of the WADC via DOF is formulated as the delay-dependent control problem.Finally,nonlinear case studies are carried out to show the effectiveness and robustness of the proposed approach.
