Abstract

There is provided a power control apparatus including an input unit to which attribute information regarding a type of generation of power is input, a determination unit configured to determine the type of generation of the power corresponding to the attribute information according to the attribute information, and a power control unit configured to control use of the power according to a determination result by the determination unit.

Claims

1. A power control apparatus comprising;

an input unit to which attribute information regarding a type of generation of power is input;

a determination unit configured to determine the type of generation of the power corresponding to the attribute information according to the attribute information; and

a power control unit configured to control use of the power according to a determination result by the determination unit.

2. The power control apparatus according to claim 1,

wherein the determination unit determines whether the power corresponding to the attribute information has a large impact on the natural environment, and

wherein the power control unit prioritizes use of energy having a small impact on the natural environment.

3. The power control apparatus according to claim 2,

wherein the determination unit determines whether the power corresponding to the attribute information is renewable energy or exhaustible energy, and

wherein the power control unit prioritizes use of the renewable energy.

4. The power control apparatus according to claim 2,

wherein the determination unit determines whether or not the power corresponding to the attribute information emits greenhouse gas at an emission amount greater than or equal to a predetermined value, and

wherein the power control unit prioritizes use of energy having an emission amount of greenhouse gas that is less than the predetermined value.

5. The power control apparatus according to claim 2,

wherein the determination unit determines whether or not the power corresponding to the attribute information is nuclear power energy, and

wherein the power control unit prioritizes use of energy that is not the nuclear power energy.

6. The power control apparatus according to claim 1, wherein the power control unit controls the use of the power according to a relationship of a fee of the power for every type of power generation.

7. The power control apparatus according to claim 6,

wherein the determination unit determines whether the power corresponding to the attribute information is renewable energy or exhaustible energy, and

wherein the power control unit controls the use of the power according to a relationship between a fee per unit amount of the renewable energy and a fee per unit amount of the exhaustible energy

8. The power control apparatus according to claim 7, wherein, when the fee per unit amount of the renewable energy is less than a sum of the fee per unit amount of the exhaustible energy and a set value, the power control unit selects the use of the renewable energy.

9. The power control apparatus according to claim 8, wherein the set value is designated according to a region or nation.

10. The power control apparatus according to claim 8, wherein the power control unit selects the use of the renewable energy and use of the exhaustible energy at a ratio corresponding to a difference between the fee per unit amount of the renewable energy and the fee per unit amount of exhaustible energy.

11. The power control apparatus according to claim 1,

wherein the determination unit determines whether the power corresponding to the attribute information is renewable energy or exhaustible energy, and

wherein, when there is surplus power of the renewable energy, the power control unit controls the surplus power to be stored.

12. The power control apparatus according to claim 1,

wherein the determination unit determines whether the power corresponding to the attribute information is renewable energy or exhaustible energy, and

wherein, when there is the surplus power of the exhaustible energy, the power control unit controls surplus power to be stored at a predetermined ratio.

13. The power control apparatus according to claim 1, wherein the power control unit controls the use of power so that a ratio of power of private power generation among power to be used in a peak time band is higher than in other time bands.

14. The power control apparatus according to claim 1, wherein the power control unit selects a type of generation of power to be preferentially used according to a weather condition, temperature or humidity.

15. The power control apparatus according to claim 1, wherein the power control unit controls electrical storage for a storage battery according to a predicted value of renewable energy to be supplied in the future.

16. The power control apparatus according to claim 1, wherein the power control unit controls the use of the power according to an actual use amount per unit time of exhaustible energy.

17. The power control apparatus according to claim 1, wherein the power control unit controls the use of the power according to other attribute information corresponding to the power.

18. The power control apparatus according to claim 1,

wherein the attribute information indicates a component ratio of the power for every type of power generation, and

wherein the power control unit controls the use of the power according to the component ratio indicated by the attribute information.

19. The power control apparatus according to claim 1, wherein the power control unit designates the type of power generation to request the power.

20. A power transmission apparatus comprising:

a power transmission unit; and

an information addition unit configured to add priority information and attribute information regarding a type of generation of power to the power to be transmitted from the power transmission unit.

21. A power control system comprising:

a power transmission apparatus; and

a power control apparatus,

wherein the power transmission apparatus includes

a power transmission unit; and

an information addition unit configured to add attribute information regarding a type of generation of power to the power to be transmitted from the power transmission unit, and

wherein the power control apparatus includes

an input unit to which the attribute information is input;

a determination unit configured to determine the type of generation of the power corresponding to the attribute information according to the attribute information; and

a power control unit configured to control use of the power according to a determination result by the determination unit.
