Power control method, and power control apparatus

A power control method for a power supplying unit for supplying power from a commercial power supply and a battery to a load, comprising:

• calculating a deviation amount between an actual remaining battery level and a predicted remaining battery level in a predetermined unit period on the basis of battery level transition data and data on the predicted remaining battery level, the battery level transition data being stored in a battery database;
• correcting a leveling target value on the basis of the calculated deviation amount, the leveling target value being a target value of power to be supplied from a commercial power supply;
• and
• controlling the power supplying unit so that the power supplying unit supplies power corresponding the corrected leveling target value from the commercial power supply.

A power control apparatus for a power supplying unit for supplying power from a commercial power supply and a battery to a load, comprising:

• a deviation calculation unit for calculating a deviation amount between an actual power demand and a predicted power demand in a predetermined unit period on the basis of power demand transition data and power demand prediction data, the power demand transition data being stored in a power database, the power demand prediction data being stored in a prediction data storing unit;
• a correction unit for correcting a leveling target value on the basis of the calculated deviation amount, the leveling target value being a target value of power to be supplied from the commercial power supply;
• and
• a control unit for controlling the power supplying unit so that the power supplying unit supplies power corresponding to the corrected leveling target value from the commercial power supply.
