Modelling files useable with Backbone modelling framework for the Finnish power system featuring a detailed hydropower cascade

The files have been created for the publication "Optimal cascade hydropower representation in energy system models: Balancing accuracy and complexity" (Kiehle et al., under review). The study assesses the impact of different hydropower representations in an open-source, national-scale energy system model with imperfect foresight. The case study simulates the Oulujoki River and the Finnish energy system in 2022. Hydrological input data has been sourced from a model developed by C. K. Nakigudde. Five setups have been created: (1) Deterministic, time series-based hydropower, (2) aggregated hydropower, (3) cascade hydropower without delay/water travel time between plants, (4) cascade with constant delay and (5) cascade with variable delay. "ModellingFiles" are GAMS-based data files that can be used to run the scenario in Backbone or display the results. The Excel files present the input data used for modelling and can also be used to run the model. The files are primarily compatible with Backbone v3.11.
