Claim:
1. A control method executed by a computer, the method causing the computer to execute the processes of: sorting a plurality of devices into a plurality of groups based on remaining energy of rechargeable batteries included in the plurality of devices; generating a virtual control plan for the plurality of groups, by changing a state in a control plan which specifies a respective state of each device in each time zone, the state indicating whether the device charges or discharges the rechargeable batteries; simulating an electric power demand for the each time zone using the virtual control plan, for the plurality of groups; updating the control plan to the virtual control plan when a simulated result is improved more than a simulated result of the control plan, for the plurality of groups, wherein the updating determines that the simulated result is improved when a peak electric power of the virtual control plan is lower than a peak electric power of the control plan; outputting the control plan when a termination condition whether a predetermined time elapses is satisfied; and updating the control plan repeatedly until the termination condition is satisfied when the termination condition is not satisfied.
