Title:
A frequency control method, a frequency control apparatus, and a storage battery system
Document Type and Number:
Japanese Patent JP6183727
Kind Code:
B2
Abstract:
Provided is a frequency regulation method for regulating a frequency of a power system so that the frequency approximates to a rated frequency, the method including: measuring the frequency; obtaining an SOC (state of charge) of a storage battery; determining a base-point of power to be charged in or discharged from the storage battery when the measured frequency is equal to a predetermined rated frequency; determining a control variable changed from the base-point by an amount corresponding to a frequency deviation that is a difference between the predetermined rated frequency and the measured frequency; and charging or discharging the storage battery based on the control variable, wherein in the determining a base-point, a third rate of change is smaller than a first rate of change and a second rate of change that are average rates of change in the base-point with respect to the SOC when the SOC is within a first range and a second range, respectively.
