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](https://tub-ensys.github.io) at the [Technical University of
Berlin](https://www.tu.berlin). Previous versions were developed by the Energy
System Modelling group at the [Institute for Automation and Applied
Informatics](https://www.iai.kit.edu/english/index.php) at the [Karlsruhe
Institute of Technology](http://www.kit.edu/english/index.php) funded by the
[Helmholtz Association](https://www.helmholtz.de/en/), and by the [Renewable
Energy
Group](https://fias.uni-frankfurt.de/physics/schramm/renewable-energy-system-and-network-analysis/)
at [FIAS](https://fias.uni-frankfurt.de/) to carry out simulations for the
[CoNDyNet project](https://fias.institute/en/projects/condynet/), financed by the [German Federal
Ministry for Education and Research (BMBF)](https://www.bmbf.de/bmbf/en/)
as part of the [Stromnetze Research
Initiative](http://forschung-stromnetze.info/projekte/grundlagen-und-konzepte-fuer-effiziente-dezentrale-stromnetze/).
## Functionality
PyPSA can calculate:
- static power flow (using both the full non-linear network equations and the
linearised network equations)
- linear optimal power flow (least-cost optimisation of power plant and
storage dispatch within network constraints, using the linear network
equations, over several snapshots)
- security-constrained linear optimal power flow
- total electricity/energy system least-cost investment optimisation (using
linear network equations, over several snapshots and investment periods
simultaneously for optimisation of generation and storage dispatch and
investment in the capacities of generation, storage, transmission and other
infrastructure)
It has models for:
- meshed multiply-connected AC and DC networks, with controllable converters
between AC and DC networks
- standard types for lines and transformers following the implementation in
[pandapower](https://www.pandapower.org/)
- conventional dispatchable generators and links with unit commitment
- generators with time-varying power availability, such as wind and solar
generators
- storage units with efficiency losses
- simple hydroelectricity with inflow and spillage
- coupling with other energy carriers (e.g. resistive Power-to-Heat (P2H),
Power-to-Gas (P2G), battery electric vehicles (BEVs), Fischer-Tropsch,
direct air capture (DAC))
- basic components out of which more complicated assets can be built, such as
Combined Heat and Power (CHP) units and heat pumps.

## Installation
pip:
```pip install pypsa```
conda/mamba:
```conda install -c conda-forge pypsa```
Additionally, install a solver (see [here](https://pypsa.readthedocs.io/en/latest/installation.html#getting-a-solver-for-optimisation)).
## Usage
```py
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](https://pypsa.readthedocs.io/en/latest/examples-basic.html) available
as [Jupyter notebooks](https://jupyter.org/). They are also available as Python scripts in
[examples/notebooks/](examples/notebooks/) directory.

## Dependencies
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:
- [pandas](http://pandas.pydata.org/) for storing data about
components and time series
- [numpy](http://www.numpy.org/) and [scipy](http://scipy.org/) for
calculations, such as linear algebra and sparse matrix calculations
- [networkx](https://networkx.github.io/) for some network
calculations
- [matplotlib](https://matplotlib.org/) for static plotting
- [linopy](https://github.com/PyPSA/linopy) for preparing optimisation problems
(currently only linear and mixed integer linear optimisation)
- [cartopy](https://scitools.org.uk/cartopy) for plotting the
baselayer map
- [pytest](http://pytest.org/) for unit testing
- [logging](https://docs.python.org/3/library/logging.html) for
managing messages
Find the full list of dependencies in the
[dependency graph](https://github.com/PyPSA/PyPSA/network/dependencies).
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](https://highs.dev/), [GLPK](https://www.gnu.org/software/glpk/) and
[CLP/CBC](https://github.com/coin-or/Cbc/) or the commercial solver
[Gurobi](http://www.gurobi.com/) for which free academic licenses are available.
