<P>PROBLEM TO BE SOLVED: To provide techniques to reduce the cost of variations in electric power usage by combination with charging and discharging of a storage battery on the basis of a Markov decision process. <P>SOLUTION: A period to which a predicted value given notice of to an electric power company is applied is preferably evenly divided into subsections. Further, for each of the subsections, on the basis of a Markov decision process including a state that depends on an electric power usage amount error, charge amount, and set target, the amount of charging and discharging of a storage battery as an action at any given time is optimally decided depending on the electric power usage amount error, charge amount, time, and set target at that time. A predetermined time in a subsection is a target setting time, at which a future target is further set as the action. The action includes deciding the charging and discharging amount in that subsection and deciding a future target in a subsection whose target should be set. <P>COPYRIGHT: (C)2013,JPO&INPIT |
