Abstract

A system tool that provides dispatchers in power grid control centers with a capability to manage changes. Included is a user interface and a plurality of scheduler engines. Each scheduler engine is configured to look ahead at different time frames to forecast system conditions and alter generation patterns within the different time frames. A comprehensive operating plan holds schedules generated by the plurality of scheduler engines. A relational database is coupled to the comprehensive operating plan. Input data is initially received from the relational database for each scheduling engine, and thereafter the relational database receives data from the scheduling engines relative to forecast system conditions.

Claims

1. A system, comprising:

a processor; and

a memory communicatively coupled to the processor, the memory having stored therein computer-executable instructions, comprising;

scheduler engines, respectively having different look-ahead periods, configured to generate respective schedules that forecast availability of at least one power generation resource that will be employed to generate electrical power in a power grid, wherein at least one scheduler engine of the scheduler engines is a mixed integer programming based optimization application and at least one other scheduler engine of the scheduler engines is a linear programming based optimization application;

the at least one scheduler engine that is the mixed integer programming based optimization application has a first look-ahead period that is longer than a second look-ahead period of the at least one other scheduler engine that is the linear programming based optimization application; and

an energy system tool configured to;

generate a comprehensive operating plan that merges the respective schedules generated by the scheduler engines; and

dispatch one or more power generation resources of the at least one power generation resource of the power grid according to the comprehensive operating plan to generate the electrical power in the power grid.

2. The system of claim 1, further comprising a user interface configured to display at least one of the respective schedules or a resource dispatch.

3. The system of claim 1, wherein at least one scheduler engine of the scheduler engines employs an emission quota in generating a schedule of the respective schedules.

4. The system of claim 1, wherein at least one scheduler engine of the scheduler engines generates a schedule based upon another schedule generated from another scheduler engine of the scheduler engines.

5. The system of claim 1, wherein the energy system tool is further configured to trigger an update of coordination of the respective schedules in response to a criterion associated with the at least one resource being determined to have been reached.

6. The system of claim 1, wherein at least one scheduler engine of the scheduler engines employs a constraint associated with number of startups for the at least one resource in generating a schedule of the respective schedules.

7. A method, comprising:

generating, by a system comprising a processor via scheduler engines respectively having different look-ahead periods, respective schedules associated with the scheduler engines that forecast availability of at least one power generation resource that will be employed to generate electrical power in a power grid, wherein at least one scheduler engine of the scheduler engines is a mixed integer programming based optimization application and at least one other scheduler engine of the scheduler engines is a linear programming based optimization application;

the at least one scheduler engine that is the mixed integer programming based optimization application has a longer look-ahead period than the at least one other scheduler engine that is the linear programming based optimization application;

12. The method of claim 7, wherein at least one scheduler engine of the scheduler engines employs a constraint associated with number of shutdowns for the at least one resource in generating a schedule of the respective schedules.

13. A non-transitory computer-readable medium having instructions stored thereon that, in response to execution, cause a system including a processor to perform operations comprising:

generating, via a group of scheduler engines respectively having different lookahead periods, respective schedules associated with the group of scheduler engines that forecast availability of at least one power generation resource that will be employed to generate electrical power in a power grid, wherein at least one scheduler engine of the group of scheduler engines is a mixed integer programming based optimization application and at least one other scheduler engine of the group of scheduler engines is a linear programming based optimization application;
