    摘要: Provided is a power adjustment device capable of adjusting the supply and demand of electric power with appropriate timing using a power storage device. The power adjustment device (10) has a difference estimation unit (12), a charging/discharging power amount calculation unit (14), and an instruction unit (16). The difference estimation unit (12) estimates a first difference between a power generation amount and a power consumption amount during a predetermined first period in intervals of time shorter than the first period. The charging/discharging power amount calculation unit (14) calculates a charging/discharging power amount, which is an amount of electric power to be charged to or discharged from a power storage device (20), on the basis of the estimated first difference and the remaining time to the end of the first period. The instruction unit (16) instructs the power storage device (20) to charge or discharge a power amount that corresponds to the calculated charging/discharging power amount.
