Charge-discharge control device, charge-discharge control system, and computer program product

摘要

According to an embodiment, a charge-discharge control device includes a receiving unit and a group controller. The receiving unit is configured to receive schedule information that indicates a schedule time at which a plurality of electric power devices, each having at least either a charging function or a discharging function, performs at least either charging or discharging. The group controller is 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 control, on a group-by-group basis, each of the electric power devices put in the charging group and each of the electric power devices put in the discharging group.

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 at least either a charging function or a discharging function and having first feasibility information set therein that indicates whether or not it is allowed to simultaneously receive a plurality of different charge controls, performs at least either charging or discharging, receive characteristic information that indicates electric power characteristics including a rated value of each of the plurality of electric power devices, and receive the first feasibility information; 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 control, on a group-by-group basis, each of the electric power devices put in the charging group and each of the electric power devices put in the discharging group; a calculator configured to, according to the characteristics information, calculate a total amount of charging of the charging group and calculates a total amount of discharging of the discharging group; and a determining unit configured to, according to the first feasibility information, determine whether or not the electric power device is allowed to simultaneously receive a plurality of charge controls, wherein according to a determination result of the determining unit and according to the schedule information, the group controller performs the grouping in such a way that the electric power device that is not allowed to simultaneously receive a plurality of charge controls do not simultaneously receive a plurality of charge controls and in such a way that the electric power devices belong to one or more charging groups, and controls the electric power devices put in the charging groups on the group-by-group basis.
