PyPSA stands for "Python for Power System Analysis". It is pronounced "pipes-ah".
PyPSA is an open source toolbox for simulating and optimising modern power and energy systems that include features such as conventional generators with unit commitment, variable wind and solar generation, storage units, coupling to other energy sectors, and mixed alternating and direct current networks. PyPSA is designed to scale well with large networks and long time series.
This project is maintained by the Department of Digital Transformation in Energy Systems at the Technical University of Berlin. Previous versions were developed by the Energy System Modelling group at the Institute for Automation and Applied Informatics at the Karlsruhe Institute of Technology funded by the Helmholtz Association, and by the Renewable Energy Group at FIAS to carry out simulations for the CoNDyNet project, financed by the German Federal Ministry for Education and Research (BMBF) as part of the Stromnetze Research Initiative.
PyPSA can calculate:
It has models for:
pip:
pip install pypsa
conda/mamba:
conda install -c conda-forge pypsa
Additionally, install a solver (see here).
import pypsa
# create a new network
n = pypsa.Network()
n.add("Bus", "mybus")
n.add("Load", "myload", bus="mybus", p_set=100)
n.add("Generator", "mygen", bus="mybus", p_nom=100, marginal_cost=20)
# load an example network
n = pypsa.examples.ac_dc_meshed()
# run the optimisation
n.optimize()
# plot results
n.generators_t.p.plot()
n.plot()
# get statistics
n.statistics()
n.statistics.energy_balance()
There are more extensive examples available as Jupyter notebooks. They are also available as Python scripts in examples/notebooks/ directory.

PyPSA is written and tested to be compatible with Python 3.9 and above. The last release supporting Python 2.7 was PyPSA 0.15.0.
It leans heavily on the following Python packages:

The optimisation uses interface libraries like linopy
which are independent of
the preferred solver. You can use e.g. one of the free solvers
HiGHS, GLPK and
CLP/CBC or the commercial solver
Gurobi for which free academic licenses are available.
