Description
Summary:Aggressive Robust Load Frequency Control of networked electric power systems necessitates the reduction of system dynamics to account for its controllability. The designed delay-free controller relies on H ∞ control enhanced with integral action to account for unknown disturbance loads. The aggressiveness is based on pole clustering within preselected regions while a gain norm minimization scheme is employed to result in small attainable gains. An a posteriori computation for the maximum allowable delay bound against measurement delays reveals the need to correlate this bound to the controller's aggressiveness. Simulation studies are used to investigate the efficiency of the suggested control scheme.
