Market Simulator

The market simulator clears the same demand and supply scenarios against the transmission network model, producing nodal prices and ancillary-services outcomes under both day-ahead and real-time designs.

Market clearing

Separating Energy and Ancillary-Services Market Clearing

Energy and reserve markets are modeled explicitly rather than blended into a single price. Energy clears through SCED, with reserves co-optimized in the same dispatch, so opportunity cost moves between the two products and each is priced on its own.

Market simulator turning demand scenarios, supply scenarios, and transmission constraints into energy and reserve market outcomes.

Outputs

Forecasting Prices, Flows, Shortfalls, and Oversupply

The simulator produces energy LMPs, reserve prices, congestion signals, line flows, supply shortfalls, oversupply conditions, and side-by-side scenario comparisons.
