Abstract

A power consumption control apparatus and a power consumption control method capable of providing a power storage being utilized as an uninterruptible power supply (UPS), and in a case of an emergency, automatically selecting a load to supply a backup power to the load, the power consumption control method including determining an occurrence of an abnormality in a supply of a grid power and a renewable power, performing an emergency mode to immediately finish a current operation of a load if it is determined that an abnormality in the supply of both of the grid power and the renewable power has occurred, and performing a standby mode to stand by until the current operation of the load is finished in a normal manner if it is determined that an abnormality in the supply of the grid power has occurred while the supply of the renewable power is normal.

Claims

1. A power consumption control method, comprising:

determining an occurrence of an abnormality in a supply of a grid power and a renewable power;

performing an emergency mode to immediately finish a current operation of a load if it is determined that an abnormality in the supply of both of the grid power and the renewable power has occurred; and

performing a standby mode to stand by until the current operation of the load is finished in a normal manner if it is determined that an abnormality in the supply of the grid power has occurred while the supply of the renewable power is normal.

2. The power consumption control method of claim 1, wherein the performing of the emergency mode comprises:

storing information of a status of the current operation of the load into a memory; and

turning off a switch that is involved in the supply of the power of the load.

3. The power consumption control method of claim 1, wherein the performing of the standby mode comprises:

standing by until the current operation of the load is finished in a normal manner; and

turning off a switch that is involved in the supply of the power of the load after the current operation of the load is finished in a normal manner.

4. The power consumption control method of claim 3, wherein the renewable power is supplied to the load during the standing by until the current operation of the load is finished in a normal manner.

5. The power consumption control method of claim 1, wherein when the load is provided in a plurality thereof and an amount of power stored at a power storage unit is less than an amount of power consumption demanded at all of the plurality of loads, some of the plurality of loads are selected, and the power is supplied only to the selected plurality of loads.

6. The power consumption control method of claim 5, wherein the selection of the some of the plurality of loads is performed by setting an order of priority based on a power usage history of each of the plurality of loads and by selecting a load having a higher order of priority first, according to the set order of priority.

7. The power consumption control method of claim 6, wherein the power usage history of the each of the plurality of loads comprises a usage frequency by a time period and an average usage time of the each of the plurality of loads.

8. The power consumption control method of claim 5, wherein the selection of the some of the plurality of loads is performed by setting an order of priority by receiving a user setting that is provided to select the some of the plurality of loads, and by selecting a load having a higher order of priority first, according to the set order of priority.

17. A non-transitory computer-readable recording medium storing a program to implement the power consumption control method of claim 1.

9. A power consumption control apparatus, comprising:

a power storage unit configured to be charged and discharged with power;

a power conversion unit configured to perform the charging and the discharging of power of the power storage unit; and

a control unit configured to determine an occurrence of an abnormality in a supply of a grid power and a renewable power;

perform an emergency mode to immediately finish a current operation of a load if it is determined that an abnormality in the supply of both of the grid power and the renewable power has occurred; and

perform a standby mode to stand by until the current operation of the load is finished in a normal manner if it is determined that an abnormality in the supply of the grid power has occurred while the supply of the renewable power is normal.

10. The power consumption control apparatus of claim 9, wherein the control unit, in a case of the emergency mode, stores information of a status of the current operation of the load into a memory;

and turns off a switch that is involved in the supply of the power of the load.

11. The power consumption control apparatus of claim 9, wherein the control unit, in a case of the standby mode, stands by until the current operation of the load is finished in a normal manner;

and turns off a switch that is involved in the supply of the power of the load after the current operation of the load is finished in a normal manner.

12. The power consumption control apparatus of claim 11, wherein the control unit supplies the renewable power to the load during a time of standing by until the current operation of the load is finished in a normal manner.

13. The power consumption control apparatus of claim 9, wherein when the load is provided in a plurality thereof and an amount of power stored at the power storage unit is less than an amount of the power consumption demanded at all of the plurality of loads, the control unit selects some of the plurality of loads, and the power is supplied only to the selected plurality of loads.

14. The power consumption control apparatus of claim 13, wherein the control unit selects the some of the plurality of loads by setting an order of priority based on a power usage history of each of the plurality of loads;

and by selecting a load having a higher order of priority first, according to the set order of priority.

15. The power consumption control apparatus of claim 14, wherein the power usage history of the each of the plurality of loads comprises a usage frequency by a time period and an average usage time of the each of the plurality of loads.

16. The power consumption control apparatus of claim 13, wherein the control unit selects the some of the plurality of loads by setting an order of priority by receiving a user setting that is provided to select the some of the plurality of loads;

and by selecting a load having a higher order of priority first, according to the set order of priority.

18. A power control method, comprising:

detecting an abnormality in at least one of a primary power supply and a secondary power supply; and

selectively enabling a first mode when an abnormality is detected in the primary power supply and the secondary power supply is normal, or a second mode when an abnormality is detected in both the primary power supply and the secondary power supply,

wherein the first mode provides power to a load while a current operation of a load is completed, and then removes power to the load, and

the second mode stores information regarding the status of the current operation of the load, and then removes power from the load.
