The above figure shows the design of the implementation. The objects Forecaster, Bidder, Tracker, and Coordinator help manage information exchange within the multiscale integrated simulation framework. The Bidder and Tracker take an IDAES model, and augment the model with necessary variables and constraints for energy system optimal bidding and tracking. The Coordinator acts as the bridge between process modeling and grid modeling. On the one hand, the Coordinator passes time to the Forecaster which then forecasts market uncertainty for the Bidder. The Bidder then calculates optimal bids and passes back to the Coordinator and the bids finally enter Prescient. On the other hand, the Coordinator passes time and market dispatches to the Tracker. The Tracker solves optimal tracking problems and passes actual energy production schedules back to the Coordinator, and these schedules will enter Prescient for settlement calculation.
