Storage Battery System and Solar Power Generation System Having the Same

摘要

A solar power generation system includes a storage battery, a solar power generation device that is provided on the side of the storage battery and outputs solar generated power, and a power control device. The power control device includes a variation component extraction unit that extracts a shade variation component from a generated power signal measured by the solar power generation device, a smoothing unit that smoothens the shade variation component obtained by the variation component extraction unit, a system output correction unit that obtains a system output power target value which is a combined output between a discharge output of the storage battery and the solar generated power on the basis of an output signal from the smoothing unit, and a charge/discharge output correction unit that corrects a charge/discharge target value which is a difference between the system output power target value and the generated power signal on the basis of a current time and a state of charge of the storage battery.
