Abstract

One embodiment of the present invention provides a system that aggregates an energy service from one or more participants. An aggregator in the system first sends a plurality of price points to a respective participant, wherein each price point corresponds to a particular range of phase angles between a voltage waveform and a current waveform. The aggregator then receives a price point selected by the participant, wherein the selected price point corresponds to a phase angle to which the participant agrees to adjust. Next, the aggregator aggregates from the one or more participants an energy service with reactive-power reduction.

Claims

1. A method for aggregating an energy service from one or more participants, comprising:

sending, by an aggregator, a plurality of price points to a respective participant, wherein each price point corresponds to a particular range of phase angles between a voltage waveform and a current waveform;

receiving, at the aggregator, a price point selected by the participant, wherein the selected price point corresponds to a phase angle to which the participant agrees to adjust; and

aggregating from the one or more participants an energy service with reactive-power reduction.

2. The method of claim 1, further comprising determining the price point based on a power factor in the power system.

3. The method of claim 1, further comprising calculating a contribution by a load of the participant to the desired average amount of the energy service based at least on the price points offered for the energy service and a reactive power level of the load.

4. The method of claim 3, wherein, after the calculation, the purchase price is fixed for the participant, who is obliged to provide a corresponding portion of the desired amount of the energy service.

5. The method of claim 1, wherein the plurality of price points sent to the participant is one of:

a vector, a matrix, a list, a table, or a function that includes a series of prices associated with the desired phase angles or phase angle changes.

6. The method of claim 1, further comprising coupling the energy service with other power sources, other power loads, or other reactive power management schemes.

7. A computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for aggregating an energy service from one or more participants, the method comprising:

sending, by an aggregator, a plurality of price points to a respective participant, wherein each price point corresponds to a particular range of phase angles between a voltage waveform and a current waveform;

receiving, at the aggregator, a price point selected by the participant, wherein the selected price point corresponds to a phase angle to which the participant agrees to adjust; and

aggregating from the one or more participants an energy service with reactive-power reduction.

8. The computer-readable storage medium of claim 7, wherein the method further comprising determining the price point based on a power factor in the power system.

9. The computer-readable storage medium of claim 7, wherein the method further comprising calculating a contribution by a load of the participant to the desired average amount of the energy service based at least on the price points offered for the energy service and a reactive power level of the load.

10. The computer-readable storage medium of claim 9, wherein, after the calculation, the purchase price is fixed for the participant, who is obliged to provide a corresponding portion of the desired amount of the energy service.

11. The computer-readable storage medium of claim 7, wherein the plurality of price points sent to the participant is one of:

a vector, a matrix, a list, a table, or a function that includes a series of prices associated with the desired phase angles or phase angle changes.

12. The computer-readable storage medium of claim 7, wherein the method further comprising coupling the energy service with other power sources, other power loads, or other reactive power management schemes.

13. A system for aggregating an energy service from one or more participants, comprising:

a sending mechanism configure to send a plurality of price points to a respective participant, wherein each price point corresponds to a particular range of phase angles between a voltage waveform and a current waveform;

a receiving mechanism configured to receive a price point selected by the participant, wherein the selected price point corresponds to a phase angle to which the participant agrees to adjust; and

an aggregation mechanism configured to aggregate from the one or more participants an energy service with reactive-power reduction.

14. The system of claim 13, further comprising a determination mechanism configured to determine the price point based on a power factor in the power system.

15. The system of claim 13, further comprising a calculation mechanism configured to calculate a contribution by a load of the participant to the desired average amount of the energy service based at least on the price points offered for the energy service and a reactive power level of the load.

16. The system of claim 15, wherein, after the calculation, the purchase price is fixed for the participant, who is obliged to provide a corresponding portion of the desired amount of the energy service.

17. The system of claim 13, wherein the plurality of price points sent to the participant is one of:

a vector, a matrix, a list, a table, or a function that includes a series of prices associated with the desired phase angles or phase angle changes.

18. The system of claim 13, further comprising a coupling mechanism configured to couple the energy service with other power sources, other power loads, or other reactive power management schemes.
