Thanks for the pull request<https://github.com/MATPOWER/matpower/pull/95>. We
can take the rest of the discussion related to this graphical representation
there.
In the mean time, are you familiar with plot_mpc() in the extras directory? If
not, please have a look at it, as it as this seems to be very similar in
intention to what Paul Cuffe implemented there.

Dear Sergio,
that sounds great. We can talk about it.
=====================================
Dear Ray,
the code, as I thought it for now, would be a function call that takes as input
the results of a power flow. It is general and not case related, so it can be
applied to every possible PF solution. It would have some options to highlight
the information needed by the user (for example the congested lines or the
lines "near to congestion", show double branches with both P and Q flows,
weight the branches or generators depending on marginal prices etc...).
For GitHub, I am new to that, so as soon as I get familiar with it, I will
create a fork and put the code there.
Thank you,
Antonio

Thanks Antonio. This does look like it could be quite useful.
Could you give us a little idea of what the public interface is to your code?
Is it a simple function call with a solved case and some options?
And what about the structure of the code? Is it a single function or multiple
functions?
I think it’ll make sense for you to make your own fork of MATPOWER and add your
code in a new branch there so we can have a look.
Thanks again for offering to contribute,
Ray

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
