Abstract

A power management device includes a power demand predicting section, demand control section, demand issuing section, and acceptance receiving section. The power demand predicting section calculates a first predicted amount of power demand, representing a result of prediction of power demand of a power consumer on a date and time in a future, and a second predicted amount of power demand, being calculated after the first predicted amount of power demand, and represents a result of prediction of power demand of the consumer on the date and time in the future. The demand control section determines a demand for prompting the consumer to adjust the amount of power demand based on the first and the second predicted amounts of power demand. The demand issuing section issues the demand determined by the demand control section to the consumer. The acceptance receiving section receives acceptance of the issued demand by the consumer.

Claims

1. A power management device comprising:

one or more processors configured to;

calculate a first predicted amount of power demand, the first predicted amount of power demand representing a result of prediction of power demand of a plurality of power consumers on a future date and time;

calculate a second predicted amount of power demand, the second predicted amount of power demand being calculated after the first predicted amount of power demand, and representing a result of prediction of power demand of the plurality of power consumers on the future date and time;

determine a demand for prompting the plurality of power consumers to adjust an amount of power demand based on the first predicted amount of power demand and the second predicted amount of power demand;

issue the determined demand to the plurality of power consumers; and

receive acceptances of the issued demand from the plurality of power consumers, wherein the one or more processors are configured to end the reception of the acceptances at a point in time that the amount of power demand adjusted by the issued demands accepted by the plurality of power consumers reaches a difference between the first predicted amount of power demand and the second predicted amount of power demand.

2. The power management device according to claim 1, wherein the one or more processors are further configured to increase or decrease points of the plurality of power consumers according to whether the plurality of power consumers has executed the issued demand.

3. The power management device according to claim 2, wherein the one or more processors are further configured to add points to the points of the plurality of power consumers when the plurality of power consumers has executed the issued demand.

4. The power management device according to claim 3,

wherein the one or more processors are further configured to assign the points to the plurality of power consumers when the plurality of power consumers has accepted the issued demand, and

when the plurality of power consumers has executed the issued demand, the one or more processors are configured to add the points assigned to the plurality of power consumers by retaining the points.

5. The power management device according to claim 2, wherein the one or more processors are further configured to subtract points from the points of the plurality of power consumers when the plurality of power consumers has not executed the issued demand.

6. The power management device according to claim 5,

wherein the one or more processors are further configured to assign points to the plurality of power consumers when the plurality of power consumers has accepted the issued demand, and

when the plurality of power consumers has not executed the issued demand that the plurality of power consumers accepted, the one or more processors are configured to subtract the points.

7. The power management device according to claim 6, wherein, when the plurality of power consumers has not executed the demand, the one or more processors are configured to subtract more points than the points given to the plurality of power consumers.

8. The power management device according to claim 2, wherein the one or more processors are further configured to increase or decrease the points of the plurality of power consumers indicating the acceptance before an end of reception of the acceptance.

9. The power management device according to claim 1, wherein the one or more processors are further configured to determine a plurality of demands as demands to be issued.

10. A power management method comprising:

calculating a first predicted amount of power demand, the first predicted amount of power demand representing a result of prediction of power demand of a plurality of power consumers on a future date and time;

calculating a second predicted amount of power demand, the second predicted amount of power demand being calculated after the first predicted amount of power demand, and representing a result of prediction of power demand of the plurality of power consumers on the future date and time;

determining a demand for prompting the plurality of power consumers to adjust an amount of power demand based on the first predicted amount of power demand and the second predicted amount of power demand;

issuing the determined demand to the plurality of power consumers; and

receiving acceptance of the issued demand from the plurality of power consumers, wherein the reception of the acceptance ends at a point in time that the amount of power demand adjusted by issued demands accepted by the plurality of power consumers reaches a difference between the first predicted amount of power demand and the second predicted amount of power demand.

11. A demand notifying device comprising:

a communicating section configured to receive a demand transmitted from a power management device;

the power management device including one or more processors configured to;

calculate a first predicted amount of power demand, the first predicted amount of power demand representing a result of prediction of power demand of a power consumer on a future date and time;

calculate a second predicted amount of power demand, the second predicted amount of power demand being calculated after the first predicted amount of power demand, and representing a result of prediction of power demand of the power consumer on the future date and time;

determine a demand for prompting the power consumer to adjust an amount of power demand based on the first predicted amount of power demand and the second predicted amount of power demand;

issue the determined demand to the power consumer;

receive acceptance of the issued demand by the power consumer;

notify the issued demand to the power consumer;

increase or decrease points of the power consumer based on an execution of the issued demand by the power consumer; and

subtract points of the power consumer when the power consumer has not executed the issued demand.

12. A power management device comprising:

one or more processors configured to;

determine a demand for prompting a plurality of power consumers to adjust an amount of power demand based on a first predicted amount of power demand, the first predicted amount of power demand representing a result of prediction of power demand of the plurality of power consumers on a future date and time;

calculate a second predicted amount of power demand, the second predicted amount of power demand being calculated after the first predicted amount of power demand, and representing a result of prediction of power demand of the plurality of power consumers on the future date and time;

issue a demand to the plurality of power consumers; and

receive acceptance of the issued demand from the plurality of power consumers, wherein the one or more processors are configured to end the reception of the acceptances at a point in time that the amount of power demand adjusted by the issued demands accepted by the plurality of power consumers reaches a difference between the first predicted amount of power demand and the second predicted amount of power demand.

13. A power management method comprising:

determining a demand for prompting a power consumer to adjust an amount of power demand based on a first predicted amount of power demand, the first predicted amount of power demand representing a result of prediction of power demand of the power consumer on a future date and time, and a second predicted amount of power demand, the second predicted amount of power demand being calculated after the first predicted amount of power demand, and representing a result of the prediction of power demand of the power consumer on the future date and time;

issuing the determined demand to the power consumer;
