| contents | This paper presents a new open-source model for simulating two-stage market clearing based on the Western Electricity Coordinating Council Anchor Data Set. We model accurate two-stage market clearing with day-ahead unit commitment at hourly resolution and real-time economic dispatch with five-minute resolution. Both day-ahead unit commitment and real-time economic dispatch can incorporate look-ahead rolling horizons. The model includes seven market regions and a full year of data, detailing 2,403 individual generation assets across diverse energy sources. The year-long simulation demonstrates the capability of our model to closely reflect the generation and price patterns of the California ISO. Our sensitivity analysis revealed that extending the ED look-ahead horizon reduces system costs by up to 0.12%. We expect this new system model to fulfill the needs of conducting electricity market analysis at finer time granularity for market designs and emerging technology integration. While we focus on the western interconnection, the model serves as a base to simulate other two-stage clearing market locations. |
