Abstract

In the present invention, in a coordinate plane that receives an expression according to a first axis indicating a parameter that impacts a basic rate and a second axis indicating a parameter that impacts a metered power rate, a display unit (230) displays an image indicating coordinates indicating the use state of power received from a grid.

Claims

1. A display apparatus which displays a usage status of power supplied from a grid, comprising:

a display unit that displays an image of a coordinate indicating a current usage status of power supplied from the grid on a coordinate plane expressed by a first axis and a second axis, wherein

the first axis is an axis indicating a parameter which affects a basic rate and indicating amount of power supplied from the grid in a first period, and

the second axis is an axis indicating a parameter which affects a metered power rate and indicating amount of power supplied from the grid in a second period which is different from the first period.

2. The display apparatus according to claim 1, wherein

a period of the second period is selectable, and

the display unit displays a usage amount of power in the period selected as the second period using the second axis.

3. The display apparatus according to claim 1, wherein

the display unit displays an image illustrating a transition of the amount of power supplied from the grid based on a history of the power supplied from the grid.

4. The display apparatus according to claim 1, wherein

the display unit displays the coordinate plane so as to provide different colors for a portion corresponding to a first quadrant and a portion corresponding to a third quadrant on the coordinate plane at the least.

5. The display apparatus according to claim 1, wherein

the first axis and the second axis cross each other on a coordinate which indicates a first target value of the amount of power supplied from the grid in the first period and a second target value of the amount of power supplied from the grid in the second period.

6. The display apparatus according to claim 1, wherein

a straight line which indicates the first target value of the amount of power supplied from the grid in the first period and a straight line which indicates the second target value of the amount of power supplied from the grid in the second period are further drawn on the coordinate plane.

7. The display apparatus according to claim 5, wherein

the first target value is a value set at each timing of the first period based on the target usage amount of power at the time of expiration of the first period.

8. The display apparatus according to claim 5, wherein

the second target value is changed at a different rate of change for each time of day, day, month, day of the week or season to which each timing of the second period belongs, and is set based on a history of the power supplied from the grid.

9. The display apparatus according to claim 5, comprising:

a control unit which expresses a coordinate of a current usage status of power supplied from the grid on the coordinate plane, based on a value of the amount of power supplied from the grid with respect to the first target value in the first period and a value of the amount of power supplied from the grid with respect to the second target value in the second period.

10. The display apparatus according to claim 1, wherein

a straight line which indicates a prescribed upper limit of the amount of power supplied from the grid is further drawn on the coordinate plane.

11. A display system comprising:

a display apparatus that displays a usage status of power supplied from a grid; and

a control apparatus that controls the display apparatus, wherein,

the display apparatus comprising;

a display unit that displays an image of a coordinate indicating a current usage status of power supplied from a grid on a coordinate plane expressed by a first axis indicating a parameter which affects the basic rate and a second axis indicating a parameter which affects a metered power rate,

the control apparatus;

expresses the amount of power supplied from the grid in a first period on the first axis, and

expresses the amount of power supplied from the grid in a second period which is different from the first period on the second axis.

12. A display method which displays a usage status of power supplied from a grid, comprising:

a step of displaying an image of a coordinate indicating a usage status of power supplied from the grid on a coordinate plane expressed by a first axis and a second axis, wherein

the first axis is an axis indicating a parameter which affects a basic rate and indicating amount of power supplied from the grid in a first period, and

the second axis is an axis indicating a parameter which affects a metered power rate and indicating amount of power supplied from the grid in a second period which is different from the first period.
