Getting a solver for optimisation¶
PyPSA passes optimisation problems for Power System Optimization to an external solver. PyPSA is known to work with the free software
and the non-free software, commercial software (for which free academic licenses are available)
For installation instructions of these solvers for your operating system, follow the links above.
Depending on your operating system, you can also install some of the open-source solvers in a
For GLPK on all operating systems:
conda install -c conda-forge glpk
For CBC on all operating systems except for Windows:
conda install -c conda-forge coincbc
Commercial solvers such as Gurobi, CPLEX, and Xpress currently significantly outperform open-source solvers for large-scale problems. It might be the case that you can only retrieve solutions by using a commercial solver.
Installing PyPSA with conda¶
If you are using
conda you can install PyPSA with:
conda install -c conda-forge pypsa
or by adding the
conda-forge channel to your
conda installation with:
conda config --add channels conda-forge
and then installing simply with:
conda install pypsa
In all of the above commands you can replace
mamba if you use this alternative.
Installing PyPSA with pip¶
If you have the Python package installer
pip then just run:
pip install pypsa
If you’re feeling adventurous, you can also install the latest master branch from github with:
pip install git+https://github.com/PyPSA/PyPSA.git
If you’re very conservative and don’t like package managers, you can just download the code from the PyPSA github repository and add the directory of PyPSA to your python path with e.g.:
import sys sys.path.append("path/to/PyPSA") import pypsa
PyPSA is only tested with the latest stable versions of all the dependent packages for the respective Python versions. Therefore it is very important that you upgrade these packages; otherwise PyPSA may not work.
To upgrade a package such as
pandas with pip, do at the command
pip install -U pandas
conda/mamba upgrade packages with:
conda update pandas
We recommend always keeping your PyPSA installation up-to-date, since bugs get fixed and new features are added.
To upgrade PyPSA with pip, do at the command line:
pip install -U pypsa
To upgrade PyPSA with conda, do at the command line:
conda update pypsa
Don’t forget to read the Release Notes regarding API changes that might require you to update your code.
