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

This is to deal with the dynamic and intermittent high-speed demand response in real time in the power system based on new renewable energy.According to the Japanese embodiment, the electric vehicle charger is a charging part for power supply and charging,In electric vehicle charging, according to the frequency measurement unit for real-time measuring the frequency of the power system and the standard frequency, compare the preset frequency variation range, and determine the stage equivalent to the above frequency based on the control standard including the charging power control proportion of multiple stages,According to the charging power control proportion in the determination stage, it may include a power control unit that automatically adjusts the charging proportion of the electric vehicle.
