Comparison of Variable Renewable Energy System (VRES) input generation models
Variable Renewable Energy Systems (VRES) such as onshore wind, offshore wind, rooftop PV, and open-field PV will play an important role in our future energy systems, and as such, they are central in our current energy system design (ESD) activities. However, in order to effectively incorporate VRES technologies into these ESD models, it is necessary to create realistic VRES generation time-series profiles to then serve as ESD inputs. Since VRES performance is derived from the design and configuration of these systems (i.e. the capacity, rotor diameter, and hub-height of a wind turbine, or the tilt, azimuth, and chemistry of a PV system) in addition to transient weather phenomena, determining these input VRES generation profiles is far from a trivial exercise.
Fortunately, there are many openly available weather datasets and VRES simulation tools available to help us generate generation profiles for our ESD activities. Many of which are being developed by openmod’ers! I think it’s time we spoke about the pros and cons of each of these tools, compared them against each other, and, if enough common ground can be found, think about the possibility of merging similar functionalities. We can also spend some time discussing “best practices” when generating VRES profiles for use in ESD analyses.
Examples of Models I have in mind are:
- Atlite for wind, PV, and hydro generation
- gsee for PV
- vwf for wind
- windpowerlib for Wind
- PVLib for PV
- SAM for…everything
- Also the simulation code for wind and PV which I wrote for my PhD thesis will be put on GitHub in the next week or so
If anyone else has other models in mind, then I think we should also consider them as well.
Anyhow, for this do-a-thon short introductions could be given for each model by those who are familiar with them. Afterward, we could compare the models against each other by performing some on-the-spot simulations, and perhaps also rate them against measured generation data. If anyone has open validation data they would like to share, this would be greatly appreciated (I will bring some). I can also bring weather extracts from MERRA2, ERA5, and COSMO for us to play around with.
