Abstract: A power demand estimation apparatus, comprising: an error measuring unit configured to measure an error of estimated power demand estimated with respect to one or more customer facilities; an error addition unit configured to obtain an added error obtained by adding errors measured with respect to segment periods in a unit term for correction, the unit term for correction including a predetermined number of consecutive series of segment periods; and a power demand estimation unit configured to estimate power demand values with respect to the respective segment periods, and correct the estimated power demand value estimated with respect to last predetermined number of segment period in the unit term for correction, based on an added error obtained with respect to the segment periods preceding the last predetermined number of segment period in the unit term for correction.

Abstract: An electric power control system for controlling supply and consumption of electric power in a system power supply, a storage battery and an electric power load, said electric power control system including: an estimated value correction unit configured to obtain a difference between a past power control estimated value and a past actual performance value, and to shift a power control estimated value obtained as a result of estimation in a predetermined period to an extent corresponding to said difference, thereby correcting the power control estimated value, wherein said past power control estimated value is a value obtained as a result of estimation performed in a past time relative to said predetermined period, and said past actual performance value is a value obtained as an actual result in the past time; and a power control unit configured to control supply and consumption of electric power in the system power supply, the storage battery, and the electric power load, based on the power control estimated value corrected by the estimated value correction unit.
