Increasing BranchResult

[annetill]

• Do you want to request a feature or report a bug?

A feature.

• What is the current behavior?

In a BranchResult we can monitor active and reactive flows.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

After the base case and after each contingency, it would be great to monitor also the tap position of a transformer, that could changes if the transformer voltage control is active.

Following the same principle, a ShuntCompenstorResult has to be created to monitor reactive flow at connection terminal and the section count, that could change if the shunt voltage control is active.

• What is the expected behavior?

• What is the motivation / use case for changing the behavior?

• Please tell us about your environment:

  • PowSyBl Version: ...
  • OS Version: ...

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, spectrum, etc)

(if a question doesn't apply, you can delete it)

Indeed, more information could be very interesting: for example, in other tools, we also get some information about the generators that reached their limit.

We could also add some information for phase shifters.

Some functional/design questions to be discussed:

1. Do we consider those new results as a new "category" of results which we could name "regulation results" ? I think it would be relevant, because it's a little different from the existing branch / bus results which are just "state" result, not results about what has acted

2. Do we want to get those results:

   • always for all regulations
   • for all regulations, only if a boolean option has been activated
   • for all regulations of a given type, only if a boolean option has been activated
   • only for regulations we asked for by their ID
