Solves power flow and optimal power flow problems

Project description

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)

Prerequisites

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

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 https://rwl.github.io/PYPOWER/ and the API documentation.
