Hi Sergio,
Are you familiar with the network reduction toolbox in the extras directory in
MATPOWER? You can see the very brief documentation
here<https://github.com/MATPOWER/mx-reduction/blob/master/Network_Reduction_Toolbox.pdf>.
How does your reduction techniques compare to the modified Ward reduction
already implemented? I would love to have these reduction capabilities enhanced
and better documented, so you are more than welcome to contribute your code and
input toward that goal.
Thanks,
Ray

Dear Antonio,
thanks for your e-mail,
your code sounds great
I work intensively in matpower for my research area (Integration of Renewable
Energy Sources in Power Systems and optimization).
At this moment, I am working in reduction technique in order to get prototype
power systems (with a small number of buses) of large size power systems, and a
graphical representation would be great.
I am interested in your idea, you can share the code and we could work on it
together to improve it.
Additionally, we can think in join papers.
You can review my last papers here:
https://www.researchgate.net/profile/Sergio_Rivera/contributions
If you want, I can share with you the reduction codes that we are using in our
reserach, or codes of my publications.
best regards

Dear developers,
sorry for the double post, but by graphical inspection (I have just understood
how useful it can be :) ) I found out that there was an error in the code,
leading to a wrong representation of the power flows, that were mixed up in the
previously attached files. You can find the updated graphs with the right
values attached to this email.
Best regards,
Antonio

Subject: Graphical representation of power flow solution
To: <MATPOWER-DEV-L@cornell.edu<mailto:MATPOWER-DEV-L@cornell.edu>>
Dear developers,
I started developing a Matlab code for the graphical representation of power
flow solutions in matlab. I think it could be a good functionality to have in
Matpower, in order to get an immediate overview of the solution.
The representation can be improved a lot to portrait more information and to be
more organized.
I attach some examples to this email.
9busPF.png
This figure shows the power flows (only the real power) for the 9bus case study.
The lines show the power flows. The arrow shows their direction. Their color
and width is proportional to the power carried. The power flows are explicitly
represented.
The generation buses are red, the load ones are green, the interconnecting ones
are blue and the ones with both load and generation are magenta. Their size is
proportional to the power generated/absorbed.
24busPF.png
In this case the graph is more minimalistic.
DC_OPF.png
In this case, the lines who reached their transmission capacity are shown in
red.
If you are interested, I can share the code and we could work on it together to
improve it.
Thanks and best regards,
Antonio Pepiciello
