Abstract

A method for load control in a load control device is disclosed. According to the method for load control of the present invention, a user intuitively recognizes the economic gain of a load control command in order to consider the efficiency of the load control system.

Claims

1. A load control method for load control apparatus, the method comprising:

receiving, from a host device, a load control message comprising a condition to be performed by load control and price-based information;

determining whether the load control message satisfies a preset condition;

transmitting a load control command to at least one load device based on the load control message when the load control message satisfies the preset load control condition; and

transmitting a response message comprising information indicating load control state to the host device or an outside device in response to the load control message.

2. The method of claim 1, further comprising:

transmitting the load control message to a display device; and

performing a load control of at least one load device in response to the load control command when the load control command is received from a user.

3. The method of claim 2, wherein the display device is included in the load control apparatus or the load device.

4. The method of claim 2, wherein the display device includes a mobile device.

5. The method of claim 1, wherein the price-based information includes information indicating a saved energy rate or a rate level corresponding to saved rate when the load control is performed.

6. The method of claim 1, wherein the preset load control condition comprises at least one of price-based information during load control and time information for load control.

7. The method of claim 1, further comprising:

receiving from the load device a request message for load activation; and

transmitting to the load device a response message indicating whether to approve of the load activation request message based on at least one of the load control message and the preset load control condition.

8. A load control method for load control apparatus, the method comprising:

receiving, from a host device, a load control message including dynamic rate information related to time;

determining whether the load control message satisfies the preset load control condition;

transmitting a load control command to at least one load device based on the load control message when the load control message satisfies the preset load control condition; and

transmitting a response message including information indicating load control state to the host device or an outside device in response to the load control message.

9. The method of claim 8, further comprising:

transmitting the load control message to a display device, and

performing the load control of devices in a consumer house in response to the load control command when the load control message is received from a user.

10. The method of claim 8, wherein the dynamic rate information includes information indicating any one of TOU (Time of Use), CPP (Critical Peak Pricing), CPR (Critical Peak Rebate) and RTP (Real Time Pricing).

11. The method of claim 8, wherein the preset load control condition includes at least one of a save amount during load control and time information for load control.

12. The method of claim 8, further comprising:

receiving, from a device in a consumer house, a request message for load activation; and

transmitting to, the device in the consumer house, a response message indicating whether to approve of the load activation request message based on at least one of the load control message and a user load control condition.
