the schedule creating section selects the devices indicated by the designation information from among the identified devices, and creates the power restriction schedule, in which the priority ranking is arranged in order of the selected devices having the highest power consumption, in association with the execution time.

5. The power demand management apparatus according to claim 1, further comprising a position information holding section that holds position information in which each of a plurality of devices are associated with a position of an area in which the device is arranged, wherein

the movement instructing section identifies the position of the area corresponding to each device by referencing the position information, and transmits to the robot movement instructions indicating the identified position.

6. The power demand management apparatus according to claim 2, further comprising a position information holding section that holds position information in which each of a plurality of devices are associated with a position of an area in which the device is arranged, wherein

the movement instructing section identifies the position of the area corresponding to each device by referencing the position information, and transmits to the robot movement instructions indicating the identified position.

7. A power demand management system comprising:

a mobile robot; and

a power demand management apparatus, wherein

the power demand management apparatus includes;

a schedule holding section that holds a power restriction schedule indicating a device on which the robot is to perform power restriction, in association with a power restriction execution time;

a movement instructing section that transmits movement instructions to the robot such that, prior to the power restriction execution time indicated in the power restriction schedule, the robot moves to an area in which is arranged the device on which the power restriction is to be performed at the execution time; and

a restriction instructing section that transmits power restriction instructions to the robot, thereby causing the robot to perform the power restriction on the device at the execution time.

8. The power demand management system according to claim 7, wherein

in response to the movement instructions, the robot provides the power demand management apparatus with operational state information indicating a current operational state of a device arranged in an area that is the movement destination.

9. The power demand management system according to claim 8, wherein

the robot includes an operational state estimating section that estimates the operational state of a device based on temperature or brightness detected by a sensor section or on an image captured by an image capturing section, associates the estimated operational state with the device, and stores this association in an operational state information holding section as the operational state information.
