Abstract: A power demand management apparatus comprising a power demand acquiring section acquiring a predicted power demand; a consumer house information holding section that, for each of a plurality of request methods or request conditions, and for each of a plurality of consumer houses, holds a sensitivity indicating a probability that the consumer house will comply with a request; a consumer house selecting section that, when the predicted power demand exceeds a target value, selects a first consumer house whose sensitivity for a first request method or request condition is no less than a first reference value and selects a second consumer house whose sensitivity for a second request method or request condition is no less than a second reference value; and a restriction requesting section that issues requests for power demand restriction to the first and second consumer houses respectively using the first and second request methods or request conditions.

Abstract: A schedule management system having a first agent that includes an acquiring means that acquires information relating to a second schedule from a second agent; a determining means that determines change content of a first schedule based on the information relating to the second schedule; an asking means that, when the change content is outside a predetermined scope of rights for the first agent, asks a user whether it is acceptable to change the first schedule based on the change content; and a changing means that, when the change content is within the predetermined scope of rights for the first agent, changes the first schedule based on the change content and, when the change content is outside the predetermined scope of rights for the first agent, changes the first schedule based on the change content or change content designated by the user, based on a result of asking the user.

Abstract: Provided is a power plan supporting apparatus comprising a power difference information acquiring section that acquires power difference amount information indicating a power difference amount between a planned power amount planned in advance by a power consumer for one unit interval within a planned period of a power usage plan and a power usage amount that is actually used during the one unit interval; and a compensation information registering section that, when the power difference amount information indicates that the power usage amount is less than the planned power amount, registers the power difference amount in the compensation information holding section as a compensation power amount that can be used by another power consumer by being added to another planned power amount of the other power consumer planned in advance for another unit interval that is later than the one unit interval.

Abstract: Due to the period during which energy reduction is performed, the benefit to society caused by the energy reduction can differ. Provided is a power cost converting apparatus comprising a power difference information acquiring section that acquires power difference amount information indicating a power difference amount between a planned power amount planned in advance for one unit interval and a power usage amount that is actually used during the one unit interval; and a power cost converting section that converts the power difference amount indicated by the power difference amount information into an index value indicating worth of the power difference amount in the one unit interval, based on a predetermined conversion coefficient determined according to the power cost during the one unit interval.

Abstract: A power demand management apparatus comprises a schedule holding section that holds a power restriction schedule indicating a device on which a mobile 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.

Abstract: Provided is a robot comprising a device manipulating section that turns ON and OFF a plurality of devices that operate by receiving power from a power supply; a power value acquiring section that acquires a first total power value that is a power value before one of the devices is turned ON or OFF by the device manipulating section and a second total power value that is a power value after the device is turned ON or OFF, via a power sensor that measures a total power value supplied to the plurality of devices from the power supply; and a power consumption estimating section that estimates power consumption of the device based on the first total power value and the second total power value.

Abstract: A power demand management apparatus comprising a power demand acquiring section acquiring a predicted power demand; a consumer house information holding section that, for each of a plurality of request methods or request conditions, and for each of a plurality of consumer houses, holds a sensitivity indicating a probability that the consumer house will comply with a request; a consumer house selecting section that, when the predicted power demand exceeds a target value, selects a first consumer house whose sensitivity for a first request method or request condition is no less than a first reference value and selects a second consumer house whose sensitivity for a second request method or request condition is no less than a second reference value; and a restriction requesting section that issues requests for power demand restriction to the first and second consumer houses respectively using the first and second request methods or request conditions.
