POWER SUPPLY SYSTEM, CONTROL DEVICE, AND POWER SUPPLY METHOD

摘要

A power supply system of an embodiment supplies power to facilities by using power obtained from a natural energy power generation device that generates the power by using a natural energy. The power supply system is equipped with: a power conditioner device for adjusting the power generated by the natural energy power generation device; a storage battery; a hydrogen production device; a hydrogen storage device; a fuel cell; and a control means for controlling the operation of at least each of the storage battery, the hydrogen production device, the hydrogen storage device, and the fuel cell. The control means determines the amounts of power supplied to the storage battery and the hydrogen production device in the daytime on the basis of at least the estimated values of the amounts of power generated by the natural energy power generation device and demanded by the facilities in the daytime, and also determines the amounts of power supplied from the storage battery to the facilities and from the fuel cell to the facilities in the nighttime.
