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 historical database coupled to a system for receiving pricing information from market participants for balancing the load requirements for energy imbalance in an energy trading market, said historical database comprising:

means for archiving historical bidding data from said market participants; and

means for collecting of control area analog measurements.

2. The historical database of claim 1, wherein said historical database processes tie-line analog measurements.

3. The historical database of claim 1, further comprising means for calculating loads for each control area.

4. The historical database of claim 1, further comprising means for collection of weather data that may be required for very short-term load forecasts and imbalance energy forecasts.

5. The historical database of claim 1, further comprising means for calculation of control area errors.

6. The historical database of claim 1, further comprising means for tracking unit response to energy imbalance controls.

7. The historical database of claim 1, further comprising means for predictive response for tracking measurements.
