First Claim
1. A charge-discharge control device comprising:
- a receiving unit configured to receive schedule information that indicates a schedule time at which a plurality of electric power devices, each having measuring function of electric flow and at least either a charging function or a discharging function, performs at least either charging or discharging;
a group controller configured to, according to the schedule information, perform grouping in such a way that each of the electric power devices belongs to either one of a charging group for performing charging and a discharging group for performing discharging; and
a selecting unit configured to select an electric power device that has a measurement function as a representative device of the charging group or the discharging group of the electric power devices, and control on a group-by-group basis, via the selected representative device, whereinfrom each of the electric power devices, the receiving unit receives at least either charge information indicating an amount of charge electric energy assigned to the charging group or discharge information indicating an amount of discharge electric energy assigned to the discharging group, andwhen the receiving unit does not receive feasibility information indicating disallowance of simultaneously belonging to a plurality of charging groups, the selecting unit selects the electric power device that has largest charge electric energy, from among a charge electric energy assigned to each charging group, as a representative device of the charging group to which belongs the electric power device having the largest charge electric energy, and when the receiving unit does not receive feasibility information indicating disallowance of simultaneously belonging to a plurality of discharging groups, the selecting unit selects the electric power device that has largest discharge electric energy, from among a discharge electric energy assigned to each discharging group, as a representative device of the discharging group to which belongs the electric power device having the largest discharge electric energy.

Abstract
According to an embodiment, a charge-discharge control device includes a receiving unit, a selecting unit, and a group controller. The receiving unit receives feasibility information. The selecting unit selects, of electric power devices that send the feasibility information indicating disallowance of simultaneously belonging to a plurality of charging groups, one electric power device as a representative device of the charging group to which belongs that electric power device; and selects, of electric power devices that send the feasibility information indicating disallowance of simultaneously belonging to a plurality of discharging groups, one electric power device as a representative device of the discharging group to which belongs that electric power device. Via the selected representative device, the group controller controls the other electric power devices belonging to the charging group or the discharging group to which belongs the selected representative device.
