Claim Text:
1. A power leveling control device which levels power supplied from a power supply in a system in which the power supply is connected to an electric cell device and a load, the power leveling control device comprising: a storage device; and a processor configured to acquire a value of electric cell residue of the electric cell device in each monitoring time, to store the value of electric cell residue of the electric cell device in the storage device, to calculate an electric cell residue representative value indicating a transition of the electric cell residue in the period based on the stored value of electric cell residue at an end of a period in which it is predicted that a period of high power demand of a load and a period of low power demand alternately appear, to determine a leveling target value for power leveling which is used in the next period and changed by a variation by determining the variation with respect to a current leveling target value based on the electric cell residue representative value, and to control power to be supplied from the power supply and the electric cell device to the load based on a determined leveling target value for the power leveling for use in the next period.
