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:

a power demand predicting section 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 date and time in a future, 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 represent a result of prediction of power demand of the power consumer on the date and time in the future;

a demand control section configured to determine a demand for prompting the power consumer to adjust the amount of power demand on a basis of the first predicted amount of power demand and the second predicted amount of power demand;

a demand issuing section configured to issue the demand determined by the demand control section to the power consumer; and

an acceptance receiving section configured to receive acceptance of the issued demand by the power consumer.

2. The power management device according to claim 1,

wherein the demand issuing section issues demands to a plurality of power consumers, and

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

3. The power management device according to claim 1, further comprising

a point control section configured to increase or decrease points of the power consumer according to whether the power consumer has executed the demand.

4. The power management device according to claim 3,

wherein the point control section adds points to the points of the power consumer when the power consumer has executed the demand.

5. The power management device according to claim 4,

wherein the point control section gives the points to the power consumer when the power consumer has accepted the demand issued by the demand issuing section, and

when the power consumer has executed the demand, the point control section adds the points given to the power consumer by retaining the points.

6. The power management device according to claim 3,

wherein the point control section subtracts points from the points of the power consumer when the power consumer has not executed the demand.

7. The power management device according to claim 6,

wherein the point control section gives points to the power consumer when the power consumer has accepted the demand issued by the demand issuing section, and

when the power consumer has not executed the demand that the power consumer accepted, the point control section subtracts the points.

8. The power management device according to claim 7,

wherein when the power consumer has not executed the demand, the point control section subtracts more points than the points given to the power consumer.

9. The power management device according to claim 3,

wherein the point control section increases or decreases the points of the power consumer indicating the acceptance before an end of reception of the acceptance.

10. The power management device according to claim 1,

wherein the demand control section determines a plurality of demands as demands to be issued.

11. 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 power consumer on a date and time in a future, 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 prediction of power demand of the power consumer on the date and time in the future;

determining a demand for prompting the power consumer to adjust the amount of power demand on a basis of the first predicted amount of power demand and the second predicted amount of power demand;

issuing the determined demand to the power consumer; and

receiving acceptance of the issued demand by the power consumer.

12. A demand notifying device comprising:

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

the power management device including

a power demand predicting section 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 date and time in a future, 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 represent a result of prediction of power demand of the power consumer on the date and time in the future,

a demand control section configured to determine a demand for prompting the power consumer to adjust the amount of power demand on a basis of the first predicted amount of power demand and the second predicted amount of power demand,

a demand issuing section configured to issue the demand determined by the demand control section to the power consumer, and

an acceptance receiving section configured to receive acceptance of the issued demand by the power consumer; and

a notifying section configured to notify the demand to the power consumer.

13. A power management device comprising:

a demand control section configured to determine a demand for prompting a power consumer to adjust an amount of power demand on a basis of 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 date and time in a future, 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 represent a result of prediction of power demand of the power consumer on the date and time in the future;

a demand issuing section configured to issue the demand determined by the demand control section to the power consumer; and

an acceptance receiving section configured to receive acceptance of the issued demand by the power consumer.

14. A power management method comprising:

determining a demand for prompting a power consumer to adjust an amount of power demand on a basis of 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 date and time in a future, 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 prediction of power demand of the power consumer on the date and time in the future;

issuing the determined demand to the power consumer; and

receiving acceptance of the issued demand by the power consumer.

15. A demand notifying device comprising:

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

the power management device including

a demand control section configured to determine a demand for prompting a power consumer to adjust an amount of power demand on a basis of 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 date and time in a future, 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 represent a result of prediction of power demand of the power consumer on the date and time in the future,

a demand issuing section configured to issue the demand determined by the demand control section to the power consumer, and
