<P>PROBLEM TO BE SOLVED: To provide a means for achieving the condition of simultaneous equal-amount for a prescribed period without using any special facilities. <P>SOLUTION: A power management apparatus 1 has an input processor 11 and a power calculation processor 13. The input processor 11 is used for acquiring information on the amount of power generation and the amount of power demand in a current time section, purchase reservation information including a desired amount of purchase of power in the future time section of a consumer. At the power calculation processor 13, the amount of power generation is compared with the amount of power demand, an estimated amount of power demand is set to be the amount of power demand when the amount of power generation is the same as the amount of power demand, the estimated amount of power demand is set to be the sum of the amount of power demand and the amount of excess power generation when the amount of power generation is larger than the amount of power consumption, the estimated amount of power demand is set to be the difference between the amount of power demand and the amount of insufficient power generation when the amount of power generation is smaller than the amount of power consumption, and the purchase reservation information is stored into a storage 14 when the sum of a desired amount of purchase in the time zone corresponding to the estimated amount of power demand is not more than the estimated amount of power demand. <P>COPYRIGHT: (C)2008,JPO&INPIT |
