摘要：[Problem] Power supply-demand adjustment among power customers andapparatuses within a given area is performed while taking into account power suppliedfrom distributed power sources. [Solution] An information processing apparatus 1receives second management information and third management information from asecond power management apparatus 2 provided to each power customer. The secondmanagement information represents an amount of power demand and an amount ofpower generation at a given future time point. The third management informationrepresents an amount of power demand and an amount of power generation adjustableby the customer. The apparatus 1 receives configuration information from a third powermanagement apparatus 4 provided to a power distribution grid. The configurationinformation includes pieces of information on power distribution apparatuses provided tothe power distribution grid, customers, and an allowable capacity of power for each ofpower distribution grid sections. The apparatus 1 calculates a sum of amounts of power

demand and a sum of amounts of power generation at the given future time point on thebasis of the second management information. The apparatus 1 calculates an amount ofpower surplus or an amount of power shortage using a difference between the sum ofamounts of power demand and the sum of amounts of power generation. The apparatus1 creates first management information based on the configuration information and theamounts of power demand or the amounts of power generation adjustable by thecustomers represented by the third management information. The first managementinformation includes a plan to reduce the amount of power surplus by increasing theamounts of power demand or reducing the amounts of power generation by thecustomers within a range not exceeding the allowable capacity of power for each powerdistribution grid section. Then, the apparatus 1 transmits the first managementinformation to the second management apparatus 2.
