Hi Mirko, Thank you. This looks very nice, and yes, I am interested in seeing MATPOWER expand it’s applicability for distribution systems. In fact, I have implemented a prototype Implicit Zbus Gauss power flow method recently with this in mind. It’s been a while since I’ve looked at these algorithms, so if you have a pointer to a good reference on how to handle PV buses, that would be great.
Regarding your code, I’m still figuring out the ideal workflows, but I think the best approach is for you to go ahead and create a pull request where we can discuss and commit any changes before accepting and merging it into the master branch. I think you’ll want to create the pull request from a branch in your repo that you are ok with giving me push access to <https://help.github.com/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork/>.
