The adverse impacts of wind power fluctuations on the power system become increasingly severe as wind turbineinstallation continues to grow. A super-capacitor energy storage（SCES） based wind power regulator is presented for smoothingpower fluctuations and controlling wind farm terminal voltage. Based on the configuration and operation principle of theregulating system， a control strategy combining wind power control， super-capacitor voltage control and power conditioningsystem（PCS） control is proposed in detail. A dynamic small-signal model of PCS is presented for PCS controller design. Theeffectiveness of the device and control strategy is validated by simulation with PSCAD/EMTDC.
