Power Conditioning Wind Power Generation System Using Energy Storage Device and thereof Control Method

摘要

PURPOSE: A power conditioning wind power generation system using an energy storage device and a control method thereof are provided to achieve optimum charge/discharge of the energy storage device through real-time output monitoring for a wind power generation device. CONSTITUTION: A power conditioning wind power generation system comprises a wind power generation device(100), an integrated control unit(500), and an energy storage device(400). The integrated control unit determines an output command value of the energy storage device in order to reduce changes in output and compensate frequency of the wind power generation device. The energy storage device absorbs and discharges electric power according to the output command value of the integrated control unit using previously stored energy. The energy storage device includes a power conversion device and one of a battery, a superconductive storage unit, a flywheel, and a super capacitor.
