A real-time active damping control of real power fluctuations in a three-phase electric network is studied and illustrated. First a real-time demodulation of real power fluctuations is proposed. Then the realization algorithm is applied to formulate a low-order state space model based on such real-time measurements of real power fluctuations. The model can accurately capture frequency and damping of the power fluctuation. Finally, a real-time active damping controller is designed by H-infinity control algorithm based on the realized model. The methodology is illustrated and validated on a test-bed integrating a grid-tied inverter, an embedded system which can implement the real-time demodulation of power fluctuations and the active damping controller, and a three-phase load circuitry.
