Swiss electricity system modeling -- HV grid - hydropower topology and inflows - renewable productions - past and forecast meteorological data
Datasets
This dataset contains several useful components for **Swiss Electricity system modeling**: 1. **High-voltage Swiss grid**: 2019 snapshot of the high-voltage (-150kV) grid composed of : - Nodes: names, voltage, position. - Lines: ends nodes, resistance, power capacity. - Transformers: ends nodes, power capacity, resistance, tap ratio. 2. **Hydropower topology** : Representative description of Swiss reservoirs and plants (2019) composed of: - Plants: Lower reservoir, Upper reservoir, pump/turbine, debit, power capacity. - Reservoirs: Volume, altitude, position, canton. 3. **Inflows** into all the reservoirs: hourly time series post-processed from PREVAH model outputs from 2009 to 2019. 4. **Wind production per node**: COSMO-1 data processed and scaled to match SFOE annual production. 5. **Solar irradiance maps projected onto tilted surfaces**: hourly time series for 35° and 65° tilts, azimuth 180°. (same method as [Frischholz, Y. (2025)](https://www.doi.org/10.16904/envidat.632)) 6. **Processed ERA5 (historical), ECMWF SEAS5 (seasonal forecast) and ECMWF TIGGE (short-term forecast)**: - ERA5 Land: For inflow forecast model: historical runoff, snow depth, temperature and total
