Readme

PYPOWER is a power flow and Optimal Power Flow (OPF) solver. It is a port of MATPOWER to the Python programming language. Current features include:

DC and AC (Newton's method & Fast Decoupled) power flow and
DC and AC optimal power flow (OPF)

Status

libraries _ pyversions _ license _ downloads _ travis _ _

PYPOWER is no longer actively maintained. However, should improvements to PYPOWER be required then the original author may be available on contract. Please do not hesitate to get in contact directly.

Prerequisites

PYPOWER depends upon these prerequisites on the level of the operating system:

Python 2.7 - 3.9

Virtual Environment

PYPOWER is recommended to be installed into a virtual environment:

$ python3.8 -m venv venv  # Or any supported Python version

Dependencies

PYPOWER depends upon NumPy, SciPy and PyRLU which can be installed as follows:

$ venv/bin/python -m pip install -r requirements.txt

Installation

The recommended way of installing PYPOWER is using pip:

$ venv/bin/python -m pip install PYPOWER

Alternatively, download and unpack the tarball and install:

$ tar zxf PYPOWER-5.x.y.tar.gz
$ venv/bin/python setup.py install

Testing

PYPOWER can be tested locally using the same tooling as on Travis CI:

$ venv/bin/python -m tox -e py27,py38  # Or any supported Python version

Using PYPOWER

Installing PYPOWER creates pf and opf commands. To list the command options:

$ venv/bin/pf -h

or:

$ venv/bin/opf -h

PYPOWER includes a selection of test cases. For example, to run a power flow on the IEEE 14 bus test case:

$ venv/bin/pf -c case14

Alternatively, the path to a PYPOWER case data file can be specified:

$ venv/bin/pf /path/to/case14.py

The opf command has the same calling syntax. For example, to solve an OPF for the IEEE Reliability Test System and write the solved case to file:

$ venv/bin/opf -c case24_ieee_rts --solvedcase=rtsout.py

For further information please refer to and the API documentation.
