PYPOWER 4.1.1

Solves power flow and optimal power flow problems

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)

Installation

PYPOWER depends upon:

• Python 2.6 or later and

• SciPy 0.9 or later.

It can be installed using pip:

$ pip install PYPOWER

Alternatively, download and unpack the tarball and install:

$ tar zxf PYPOWER-4.x.y.tar.gz
$ python setup.py install

Using PYPOWER

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

$ pf -h

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

$ pf -c case14

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

$ 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:

$ opf -c case24_ieee_rts --solvedcase=rtsout.py

For further information please refer to http://www.pypower.org/ and the API documentation.
