MISO is working on Market Roadmap Item 002 – Enhanced Modeling of Combined Cycle Generators, and is moving into the conceptual design phase of the project. The goal of this project is to develop modeling of combined cycle units in the both the DA and RT SCUC/SCED algorithms that will allow market participants with these types of units to submit offer data on different unit/equipment configurations, distinct component operating characteristics, and transition constraints and notification times. Given this offer data, the enhanced SCUC/SCED algorithms would commit and dispatch the most economic unit configuration on an hourly basis. We believe this same approach could be expanded to include equipment operating characteristics and transition constraints of other types of generation resources (e.g., transition constraints due to starting and stopping of coal mills, boiler feedpumps, etc.).
