Systems and methods for local autonomous response to grid conditions by electric vehicle charging stationsas and other similar loads

摘要

A system for generating a local autonomous response to a condition of an electric grid by electric vehicle charging stations, comprising: a first electricity meter for reading current, frequency, or voltage from a first electricity supply line to one electric vehicle charging station; a second electricity meter for reading an electric current, frequency, or voltage from the electric grid supplying the plurality of electric vehicle charging stations; a third electricity meter for reading current, frequency, or voltage from a third electricity line from one or more renewable generators; and an electric vehicle charging controller operatively coupled to the first electricity meter, the second electricity meter, the third electricity meter and the electric vehicle charging stations and operable to obtain readings from the first electricity meter, the second electricity meter and the third electricity meter and to control the electric vehicle charging stations based on the obtained readings.
