POWER-LEVELING CONTROL DEVICE, POWER-LEVELING CONTROL METHOD, AND PROGRAM

摘要

A power-leveling device has a power measuring unit, a maximum charging amount determination unit, and a control unit. The power measuring unit measures the power supplied from a power supply or the amount of power per unit time. The maximum charging amount determination unit compares a target value with the maximum value of the power supplied from the power supply or the maximum value of the amount of power per unit time, both of which are measured by the power measuring unit after a first time in the past. The maximum charging amount determination unit sets, to a maximum charging amount for an electricity storage device to be allowed to be charged, a power or an amount of power by which the measured power or amount of power per unit time is fallen below the smaller one of the compared values. The control unit allows power to be supplied to a load from the power supply and charges the electricity storage device in the range not exceeding the maximum charging amount when the measured power or amount of power is the target value or less, and allows the electricity storage device to discharge and supply power to the load when the target value is exceeded. Accordingly, a leveling performance can be prevented from being degraded even if the target value is inappropriate.
