Abstract

Provided are a demand response method and system. A household demand response apparatus includes: a signal reception unit which receives a critical peak notification message; a display unit which displays the received critical peak notification message and displays an inquiry message inquiring whether to interrupt power supply during a time section in which a critical peak occurs; and a control unit which controls the power supply based on a response to the inquiry message.

Claims

1. A household demand response apparatus comprising:

a signal reception unit which receives a critical peak notification message;

a display unit which displays the received critical peak notification message and displays an inquiry message inquiring whether to interrupt power supply during a time section in which a critical peak occurs; and

a control unit which controls the power supply based on a response to the inquiry message.

2. The apparatus of claim 1, wherein the critical peak notification message is determined based on a power consumption pattern and price volatility in a wholesale electricity market.

3. The apparatus of claim 1, wherein the critical peak notification message is displayed a predetermined number of times during a predetermined period of time.

4. The apparatus of claim 1, further comprising a storage unit which stores a power supply reservation made for the time section, wherein the control unit controls the power supply during the time section based on the stored power supply reservation.

5. The apparatus of claim 1, further comprising a user input unit which provides a medium by which a user can input the response.

6. The apparatus of claim 1, wherein, when the user fails to input the response, the control unit interrupts the power supply during the time section.

7. A demand response method comprising:

displaying a critical peak notification message;

displaying an inquiry message inquiring whether to interrupt power supply during a time section in which a critical peak occurs; and

controlling the power supply based on a response to the inquiry message.

8. The method of claim 7, wherein the critical peak notification message is determined based on a power consumption pattern and price volatility in a wholesale electricity market.

9. The method of claim 7, wherein the critical peak notification message is displayed a predetermined number of times during a predetermined period of time.

10. The method of claim 7, wherein the controlling of the power supply comprises, if a power supply reservation made for the time section is available, controlling the power supply during the time section based on the power supply reservation made for the time section.

11. The method of claim 7, wherein a user directly inputs the response.

12. The method of claim 7, wherein, when the user fails to input the response, the controlling of the power supply comprises interrupting the power supply during the time section.

13. An energy service provider system comprising:

a price estimation unit which estimates an electricity price to be determined in an electricity market;

a consumption pattern classification unit which provides power consumption pattern information of each user;

a critical peak determination unit which determines an electricity price and when to generate a critical peak pricing (CPP) event based on the estimated electricity price and the provided power consumption pattern information; and

a demand response unit which transmits a CPP event signal based on the determination result of the critical peak determination unit.

14. A demand response system comprising:

an energy service provider who transmits a CPP event signal based on a power consumption pattern of a user; and

a household demand response apparatus which receives the CPP event signal, displays details of a CPP event, and controls power supply during a time section, in which a CPP rate is applied, based on the user'"'"'s response.
