Claim:
1. A method for controlling power supply, the method comprising: receiving, by a demand response apparatus from a supply resource utilizing apparatus, a signal requesting a power supply from the demand response apparatus, wherein the demand response apparatus is configured to consume different power usage depending on an operation of the demand response apparatus, and the signal includes a start time and an end time when the power supply is required, and one of an incentive indicating a cost being paid per unit power and a demand level indicating a difference between an amount of power being demanded and an amount of power being supplied; estimating a first power usage to be consumed by an ongoing or scheduled operation of the demand response apparatus for a first time interval based on the received signal, wherein the first time interval comprises a time interval from the start time to the end time; determining to adjust the ongoing or scheduled operation of the demand response apparatus based on one of the incentive and the demand level; estimating a second power usage to be consumed by the adjusted operation of the demand response apparatus for the first time interval; calculating an available power supply to be saved by the demand response apparatus based on the estimated first power usage and the estimated second power usage; transmitting, by a demand response apparatus, information about the available power supply to the supply resource utilizing apparatus; and adjusting the ongoing or scheduled operation of the demand response apparatus based on the determining result, wherein the information about the available power supply comprises a start time and an end time of a second time interval included in the first time interval, and a plurality of available power supply values corresponding to a plurality of intervals in the second time interval.
