deflex - flexible multi-regional energy system model for heat, power and mobility¶
++++++ multi sectoral energy system of Germany/Europe ++++++ dispatch optimisation ++++++ highly configurable and adaptable ++++++ multiple analyses functions +++++
The following README gives you a brief overview about deflex. Read the full documentation for all information.
To run deflex you have to install the Python package and a solver:
- deflex is available on PyPi and can be
pip install deflex.
- an LP-solver is needed such as CBC (default), GLPK, Gurobi*, Cplex*
- for some extra functions additional packages and are needed
* Proprietary solver
pip install deflex[example]to get all dependencies.
- Create a local directory (e.g. /home/user/deflex_examples).
- Browse the examples for deflex v0.4.x or download all examples as zip file and copy/extract them to your local directory.
- Read the comments of each example, execute it and modify it to your needs. Do not forget to set a local path in the examples if needed.
- In parallel you should read the
usage guideof the documentation to get the full picture.
The example scripts will download the example scenarios to the $HOME/deflex folder. It is also possible to browse the example scenarios.
We are warmly welcoming all who want to contribute to the deflex library. This includes the following actions:
- Write bug reports or comments
- Improve the documentation (including typos, grammar)
- Add features improve the code (open an issue first)
Go to the Zenodo page of deflex to find the DOI of your version. To cite all deflex versions use:
The following figures will give you a brief impression about deflex.
Figure 1: Use one of the include regions sets or create your own one. You can also include other European countries.
Figure 2: The input data can be organised in spreadsheets or csv files.
Figure 3: The resulting system costs of deflex have been compared with the day-ahead prices from the Entso-e downloaded from Open Power System Data. The plot shows three different periods of the year.
Figure 4: It is also possible to get a time series of the average emissions. Furthermore, it shows the emissions of the most expensive power plant which would be replaced by an additional feed-in.
Figure 5: The following plot shows fraction of the time on which the utilisation of the power lines between the regions is more than 90% of its maximum capacity:
