PYPOWER 5.1.4

Solves power flow and optimal power flow problems

Development Status

PYPOWER is no longer actively maintained.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.

Introduction

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 2.6-3.6 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 https://rwl.github.io/PYPOWER/ and the API documentation.
