Abstract

Methods are provided that enable dispatchers in power grid control centers to manage changes. A comprehensive operating plan is provided with multiple, security constrained economic dispatch engines 1, 2 and 3. The scheduler engines are security constrained unit commitments and economic dispatch sequences with different look-ahead periods. The comprehensive operation plan is configured to integrate scheduler engines into a unified scheduling system. The comprehensive operating plan includes a repository of all operating plans in a multi-stage decision process.

Claims

1. A method for providing dispatchers in power grid control centers with a capability to manage changes, comprising:

providing a comprehensive operating plan that has multiple dispatch engines 1, 2 and 3; and

wherein the dispatch engines are security constrained unit commitments and economic dispatch sequences with different look-ahead periods, the comprehensive operation plan being configured to integrate the security dispatch engines into a unified scheduling system.

2. The method of claim 1, wherein the comprehensive operation plan coordinates scheduling data to and from a certain class of power grid system applications and presents a comprehensive, synchronized and harmonized view of scheduling data to at least one of, applications, power grid system operators and other stakeholders for power grid system operations.

3. The method of claim 1, wherein the comprehensive operation plan has at least one of, a presentation layer and a set of operator user interfaces of its own to support power grid system operator decision making.

4. The method of claim 3, wherein the comprehensive operation plan has a service layer to provide a set of front end programming'"'"'s to interact with at least one of, external power grid system applications and data sources.

5. The method of claim 4, wherein comprehensive operation plan has a business application layer that performs at least one of, validation, translation, transformation, consolidation and harmonization of selected asynchronized scheduling data.

6. The method of claim 5, wherein the comprehensive operation plan has a persistence data layer for some selected key scheduling data.

7. The method of claim 6, wherein the class of scheduling data of interest is selected from at least one of, resource, megawatt schedule, demand forecast, outage schedule, transaction and interchange schedule, transmission constraint limit schedule, reserve and regulation requirement schedule and resource characteristics schedule.

8. The method of claim 1, wherein the comprehensive operation plan contains summary information.

9. The method of claim 1, wherein the summary information is at least one rollups from a raw data at a lower level.

10. A method for providing dispatchers in power grid control centers with a capability to manage changes, comprising:

providing a comprehensive operation plan that has multiple dispatch engines 1, 2 &

3;

wherein the scheduler engines are security constrained unit commitments and economic dispatch sequences with different look-ahead periods, the comprehensive operation plan being configured to integrate scheduler engines into a unified scheduling system, and

wherein the comprehensive operation plan includes a repository of all operating plans in a multi-stage decision process.

11. The method of claim 10, wherein each stage in the multi-stage decision process generates a set of schedules that are reflected in its corresponding comprehensive operation plan i.

12. The method of claim 11, wherein aggregated results from the multi-stage decision process are captured in a total comprehensive operation plan t.

13. The method of claim 12, wherein comprehensive operation plant is a merged outcome of individual comprehensive operation plans i.

14. A method for providing dispatchers in power grid control centers with a capability to manage changes, comprising:

providing a comprehensive operating plan that has multiple, dispatch engines 1, 2 and 3; and

wherein the scheduler engines are security constrained unit commitments and economic dispatch sequences with different look-ahead periods, the comprehensive operation plan being configured to integrate scheduler engines into a unified scheduling system; and

wherein the comprehensive operation plan contains quantities that are scheduled over different operating intervals.

15. The method of claim 14, wherein operator interaction is with comprehensive operating plan t.

16. The method of claim 14, wherein the comprehensive operation plan contains individual resource level and comprehensive summary information.

17. The method of claim 16, wherein the summary information includes rollups from a resource level or stored in a database.

18. The method of claim 17, wherein the comprehensive operation plan includes power grid system level information selected from one or more of, power grid system/area demand forecast, and reserve requirements

19. The method of claim 14, wherein at least a portion of comprehensive operating plan i contents are not identical and allow for explicit translation/transformation between each comprehensive operating plan i and comprehensive operating plan t.

20. A method for providing dispatchers in power grid control centers with a capability to manage changes, comprising:

providing a comprehensive operating plan that has multiple dispatch engines 1, 2 and 3;

wherein the scheduler engines are security constrained unit commitments and economic dispatch sequences with different look-ahead periods, the comprehensive operation plan being configured to integrate scheduler engines into a unified scheduling system; and

wherein the comprehensive operation plan has a schedule time-line that is a variable time duration.
