Solves power flow and optimal power flow problems
- DC and AC (Newton’s method & Fast Decoupled) power flow and
- DC and AC optimal power flow (OPF)
PYPOWER depends upon these prerequisites on the level of the operating system:
- Python 2.7 - 3.9
PYPOWER is recommended to be installed into a virtual environment:
$ python3.8 -m venv venv # Or any supported Python version
PYPOWER depends upon SciPy, which can be installed as follows:
$ venv/bin/python -m pip install -r requirements.txt
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
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
Installing PYPOWER creates pf and opf commands. To list the command options:
$ venv/bin/pf -h
$ 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
