Introduction to pypower?

[Johnny]

I just found PyPower and was really glad to see some power systems code
already available for working with in Python, as I've been scouting for
some power systems tools in Python for a while. Being reasonably new to
Python as well, it would be interesing to hear:

1) Are there any other promising power system tools for Python out there?

2) Is there any source of simple tutorials available to run from Python,
or is the Matpower site the best source?

3) The first thing I did after I got the modules imported in Python was
to suppress the default printing to stdout (i.e. commenting out line 291
in runpf.py; "printpf(results, stdout, ppopt)"). At least it would be
reasonable to get no output if a file is given, but even so the screen
gets cluttered. Or am I missing some obvious option?

4) What are the plans for PyPower and how active is development?

5) How does the google groups mailing list work? Can I just be added to
the subscription as for a normal mailing list, a.k.a. 'join'?

Thanks for a great package so far!

Dome by Federico Milano is very promising.

I'd highly recommend the accompanying book too. OpenDSS can be
accessed from Python via the COM interface.

http://sourceforge.net/projects/electricdss/

I am working on a Python translation of OpenDSS, but it is far from
completion.

PyPower has much the same API as Matpower. The Matpower manual and
mailing list should help you to get started.

The OUT_ALL option will allow you to suppress the output. Try:

ppopt = ppoption(OUT_ALL=0, VERBOSE=0)
runpf(ppc, ppopt)

I will try to keep up with future versions of Matpower. The branch
based on v3.2 is not fully working yet. I'm working on a non-linear
solver in Python to include as it currently relies on PyIPOPT.

I think if you join the group new posts will be emailed to you.

I'm glad you appreciate it. I am working on a Java translation too if
you are interested:
