Fast DR ELECTRIC VEHICLE CHARGER APPLIED FAST DEMAND RESPONSE IN ANCILLARY SERVICE OF ELECTRIC POWER SYSTEM METHOD AND APPARATUS FOR CONTROLLING CHARGING POSER OF THE ELECTRIC VEHICLE CHARGER

摘要

It relates to an electric vehicle charger for high-speed demand response for real-time response to volatility and intermittentness in a renewable energy-based power system. An electric vehicle charger according to an embodiment includes a charging unit that charges an electric vehicle by supplying power, a frequency measurement unit that measures a frequency of a power system during charging of the electric vehicle in real time, and the charged power of the electric vehicle based on the measured frequency and control criteria. It may include a power control unit to control.
