1. An electric power adjusting device configured to execute:
acquiring vehicle information of a plurality of electric vehicles connected to a power utility grid;
classifying, based on the vehicle information, the plurality of electric vehicles into a plurality of groups according to predetermined characteristics;
sending a control signal to control charging and discharging of the plurality of electric vehicles connected to the power utility grid; and
adjusting a charging and discharging burden on the plurality of electric vehicles for each of the plurality of groups when adjusting an electric power demand in the power utility grid, wherein
each of the plurality of electrical vehicles is configured to, in response to receiving the control signal, adjust the charging and discharging of an on-board battery of a corresponding electrical vehicle of the plurality of electric vehicles,
the vehicle information includes classification information of the plurality of electric vehicles, and
the classifying the electric vehicles includes classifying the plurality of electric vehicles into
a first group consisting of battery electric vehicles (BEVs) and assigned to take care of a first period component, the first period component being a waveform capturing changes in the electric power demand at first intervals,
a second group excluding BEVs and assigned to take care of a second period component, the second period component being a waveform capturing the changes in the electric power demand at second intervals less than the first intervals, and
a third group excluding BEVs and assigned to take care of a third period component, the third period component being a waveform capturing the changes in the electric power demand at third intervals less than the second intervals.
