Abstract

A method and apparatus for resolving energy imbalance in a real-time manner is disclosed. A plurality of market user interfaces are coupled to an imbalance engine which determines optimal dispatch requirements corresponding to supply and demand requirements of the market participants. The imbalance engine resolves in a real-time manner the dispatch requirements while considering the transmission limitations, ramping limitations, transmission facilities, and price data.

Claims

1. A system for balancing the load requirements for energy imbalance in an energy trading market, said system comprising:

a plurality of market user interfaces, each market user interface receiving from a plurality of market participants supply and demand requirements for imbalance energy; and

an imbalance engine coupled to said plurality of market user interfaces for determining optimal market dispatch corresponding to said supply and demand requirements.

2. The system of claim 1, wherein said optimal market dispatch is calculated in real-time.

3. The system of claim 2, wherein said optimal market dispatch is calculated in real-time for a plurality of control areas.

4. The system of claim 1, wherein said optimal market dispatch is calculated in five minute intervals.

5. The system of claim 1, wherein said market user interface further receives pricing information from said market participants.

6. The system of claim 5, wherein said pricing information is in a step-wise price curve.

7. The system of claim 5, wherein said pricing information is in a piecewise linear price curve form.

8. The system of claim 1, wherein said market user interface receives pricing information from said market participants in fixed time intervals.

9. The system of claim 8, wherein said fixed time interval is fifteen minutes.

10. The system of claim 1, wherein said imbalance engine further compromises:

a market database;

an optimal market dispatch coupled to said market database;

a load forecast coupled to said optimal market dispatch;

a HIS database coupled to said load forecast;

a pricing engine coupled to said optimal market dispatch.

11. The system of claim 10, wherein said market database tracks bidding data from said market participants.

12. The system of claim 10, wherein said optimal market dispatch processes bidding data from said market participants.

13. The system of claim 10, wherein said optimal market dispatch processes clearance data from said market participants.

14. The system of claim 13, wherein said optimal market dispatch further performs clearing of imbalance energy bids across a plurality of control areas.

15. The system of claim 10, wherein said pricing engine generates optimal pricing parameters for dispatched instructions.
