Abstract

A method is provided for merging different load forecasts for power grid centers. Area load forecasts are accepted from load forecast engines. A relational database saves load forecast engine data. A comprehensive operating plan integrates individual load forecasts into a composite load forecast to present a comprehensive, synchronized and harmonized load forecast.

Claims

1. A method, comprising:

receiving, by a system comprising a processing device, data describing area load forecasts associated with multi-stage engines, wherein at least one multi-stage engine of the multi-stage engines is an engine external to the system; and

integrating the data describing the area load forecasts into a composite load forecast.

2. The method of claim 1, further comprising:

integrating, based on the composite load forecast, at least one of scheduling of resources, commitment of the resources, or dispatch of the resources associated with a set of the multi-stage engines into a composite operating plan that synchronizes at least one of the scheduling of resources, the commitment of the resources, or the dispatch of the resources associated with a set of the multi-stage engines.

3. The method of claim 2, further comprising:

generating, based on the composite operating plan, a unified scheduling framework comprising other data that facilitates coordination of a series of resource scheduling processes.

4. The method of claim 1, further comprising:

determining a scheduling period,

wherein the integrating further comprises integrating the data based on the scheduling period.

5. The method of claim 1, further comprising:

based on a most recent complete composite load forecast, generating an area load forecast associated with a multi-stage engine of the multistage engines.

6. The method of claim 1, further comprising:

generating a respective load forecast associated with a multi-stage engine at a time period.

7. A system, comprising:

a memory to store computer-executable instructions; and

a processor, coupled to the memory, that executes or facilitates execution of the computer-executable instructions to at least;

receive data describing area load forecasts associated with a plurality of multi-stage engines; and

integrate a set of the load forecasts into a composite load forecast representing a synchronized load forecast associated with resources of a power grid.

8. The system of claim 7, wherein the processor further executes or facilitates the execution of the computer-executable instructions to modify the area load forecast based on input received by the system.

9. The system of claim 7, wherein the processor further executes or facilitates the execution of the computer-executable instructions to generate the composite load forecast based on a selection criterion.

10. The system of claim 9, wherein the selection criterion comprises at least one of a geographic location, a time range, a cost associated with the resources of the power grid, or a periodic interval.

11. The system of claim 7, wherein the processor further executes or facilitates the execution of the computer-executable instructions to send case data to another system representing an analysis case result defining a result of the integration.

12. The system of claim 7, wherein the processor further executes or facilitates the execution of the computer-executable instructions to integrate the load forecasts based on a criterion associated with at least one of scheduling of resources, commitment of the resources, or dispatch of the resources associated with the plurality of the multi-stage engines.

13. A computer-readable storage device having components stored thereon that, in response to execution, cause an apparatus comprising a processor to perform operations, the components comprising:

a set of multi-stage engine components configured to generate area load forecasts; and

a demand forecast integrator component configured to integrate, based on a criterion, at least a subset of the area load forecasts into a composite load forecast.

14. The computer-readable storage device of claim 13, further comprising:

an interface component configured to display at least the subset of the area load forecasts and modify at least the subset of the area load forecasts based on changes to the area load forecasts.

15. The computer-readable storage device of claim 14, wherein the demand forecast integrator component is further configured to verify, based on a security criterion, whether or not the changes are valid.

16. The computer-readable storage device of claim 13, wherein the demand forecast integrator component is further configured to select at least the subset of the area load forecasts that are associated with a defined time range to form the composite load forecast.

17. The computer-readable storage device of claim 13, wherein the demand forecast integrator component is further configured to, based on the composite load forecast, at least one of schedule resources, commit the resources, or dispatch the resources associated with the set of the multi-stage engine components, to generate a composite operating plan that represents a synchronized operating plan for at least one of the scheduling of the resources, commitment of the resources, or dispatching of the resources associated with the set of the multi-stage engine components.

18. The computer-readable storage device of claim 17, wherein the multi-stage engine components are further configured to, in response to an output of the demand forecast integrator component, generate the composite operating plan, generate an updated set of the area load forecasts, and wherein, the demand forecast integrator component is further configured to integrate the updated set of the area load forecasts into the composite load forecast.

19. The computer-readable storage device of claim 13, wherein the components further comprise:

a persistence resource component that supports auditing and archiving of the area load forecasts.

20. The computer-readable storage device of claim 13, wherein the multi-stage engine components are further configured to generate respective area load forecasts at a different time to provide at least one of scheduling of resources, commitment of the resources or dispatch of the resources.
