stELMOD is a stochastic optimization model for analyzing the impact of uncertain wind generation on the following day and intraday electricity markets as well as network congestion management. After clearing of the daily following day and the subsequent hourly intraday markets, the final power plant dispatch is determined by the transmission system operator considering network congestion arising from previous market commitments. The consecutive clearing of the electricity markets is incorporated by a rolling planning procedure resembling the market process of most European markets.

Below you find an overview of available open-source stELMOD versions. The ZIP file includes the GAMS code and data files with all necessary input parameters.

The model is implemented in the General Algebraic Modeling System (GAMS). Running the model thus requires a GAMS system, a MIP solver, and the respective licenses. We use the commercial solver CPLEX.
