scripts for simulating wind power generation from ERA5 and MERRA-2 reanalysis data with Global Wind Atlas version 2 and 3 bias correction and validation with wind power time series.

The results of Austria (outdated) and Brazil were presented at the IEWT 2019 (Internationale Energiewirtschaftstagung 13.-15.Feb 2019, Vienna) https://iewt2019.eeg.tuwien.ac.at/programme_text Full Paper: https://iewt2019.eeg.tuwien.ac.at/download/contribution/fullpaper/146/146_fullpaper_20190130_090240.pdf Version: https://github.com/KatharinaGruber/windpower_GWA/tree/iewt

These results complemented with results from South Africa were presented at EGU 2019 (European Geosciences Union General Assembly 7. - 12. Apr 2019, Vienna).

These results complemented with results from the USA were presented at ICEM 2019 (6th International Conference Energy & Meteorology 24. - 27. Jun 2019, Copenhagen).

Simulation and analysis of wind power generation in Brazil, New Zealand, USA and South Africa is performed in Python. The scripts BRA/run_bra_simulation.sh NZ/run_NZ_simulation.sh USA/run_usa_simulation.sh ZAF/run_ZAF_simulation.sh run the simulation for each country.

Each simulation consists of

• reanalysis data download (ERA5 and MERRA-2)
• wind power simulation for each of the reanalysis with and without GWA
• for the GWA simulation between GWA2 and GWA3 can be chosen
• computation of statistical parameters for simulation

GWA needs to be downloaded manually, as well as wind park information data and validation data More information can be found in the related publication (Preprint) https://arxiv.org/abs/2012.05648

Info for Austria (outdated):

Note that there was an issue: Two different resolutions are used in the GWA as it was updated in the meantime: 1km for Austria and Brazil and 250m for South Africa and USA More recent simulations are using GWA2 and GWA3, both with a resolution of 250m

Simulation for Austria was done in R:

the files "RSkript_aut_3.R" and "RSkript_bra_3.R" contain the main part of the simulation and analysis, including download the files "ERA5_data.R" and "ERA5_dat_bra.R" contain functions for the download and file conversion of ERA5 wind speed data, the latter is used for Brazil, because the method applied for Austria did not work for Brazil due to larger file sizes in "functions_aut_2.R" and "functions_bra_2.R" the functions used for simulation and analysis are contained in "RSkript_bra_country_monthly.R" and "RSkript_bra_states.R" further analysis for ICEM results is conducted
