Electric device and power management apparatus for changing demand response (DR) control level
First Claim
1. An electric device for changing a demand response (DR) control level, comprising:
- a processor, comprising;
a memory unit to store one of a plurality of DR control levels each corresponding to a power rate level as a start level of the power saving operation;
a communication unit to receive a current power rate and a current power rate level related to the current power rate from a power provider;
a user interface which, upon receiving a request for changing a DR control level to a desired DR control level from a user, displays a list of the stored DR control levels and receives the desired DR control level from the user; and
a controller to compare the current power rate level with the desired DR control level from the plurality of DR control levels, and to determine whether to perform a power saving operation,wherein the controller sets a product recommended DR control level pre-stored in the memory unit when the product is manufactured to the start level of the power saving operation, and sets the desired DR control level to the start level of the power saving operation upon receiving a request for changing the DR control level to the desired DR control level from the user interface.

Abstract
An electric device for changing a DR control level and a power management apparatus for the same are disclosed. An electric device for changing a demand response (DR) control level includes a memory unit to store a plurality of DR control levels classified according to power rates, a communication unit to receive a current power rate and a current power rate level related to the current power rate from a power provider in real time, a user interface which, upon receiving a request for changing a DR control level from a user, displays a list of pre-stored DR control levels and receives a DR control level to be changed from the user, and a controller to compare the current power rate level with the changed DR control level, and determine whether to perform a power saving operation. As a result, the electric device can decide whether to increase the usage of the electric device or to consider the power saving aspect using current power status information transmitted in real time, thereby adaptively adjusting a start level of the DR control.

18. A method of controlling electric devices, comprising:
-
storing a plurality of demand response (DR) control levels of electric devices classified according to power rates; receiving a current power rate level related to a current power rate from a power provider; comparing, by a processor, the current power rate level with a desired DR control level selected by a user from the plurality of DR control levels; performing power saving operation to at least one of electric devices based upon the comparison, wherein a start level of the power saving operation is one of a plurality of DR control levels each corresponding to a power rate level; and setting, by the processor, a product recommended DR control level pre-stored in a memory unit when the product is manufactured to the start level of the power saving operation, and setting the desired DR control level to the start level of the power saving operation upon receiving a request for changing the DR control level to the desired DR control level from the user interface.
