Claim Text:
1. A device for adjusting a plan of demand for power to charge rechargeable batteries, communicatively connected to each of a supply-demand planning device and a demand planning device, the supply-demand planning device calculating an optimal value of demand for power per unit time as well as calculating an optimal value of power price per the unit time, and the demand planning device planning demand for power to charge the rechargeable batteries in accordance with the power price, the device comprising: an optimal supply-demand plan acquiring unit configured to acquire from the supply-demand planning device an optimal value of the demand for power and an optimal value of the power price per the unit time; an optimal demand acquiring unit configured to control the demand planning device to plan the amount of demand according to the optimal value of the acquired power price and acquire a planned value of the amount of demand from the demand planning device; a group determining unit configured to divide the rechargeable batteries into a plurality of groups; a demand plan statistical computing unit configured to compute a statistical value, for each of the groups, by statistically computing a plan value of the amount of demand of the rechargeable batteries; a price adjusting unit configured to raise the power price for the unit time at which the planned value of the amount of demand of the rechargeable batteries belonging to the group exceeds the optimal value of the amount of demand, in descending order of the statistically computed value, and to control the demand planning device to plan the amount of demand according to the raised power price; and a unit configured to charge the rechargeable batteries according to the plan.
