Please check if the PR fulfills these requirements

• The commit message follows our guidelines
• Tests for the changes have been added (for bug fixes / features)
• Docs have been added / updated (for bug fixes / features)

Does this PR already have an issue describing the problem?
Fixes #1124

What kind of change does this PR introduce?
If the bus of a generator with remote voltage control on , and reactivie limits, is approaches the realistic voltage limit, the generator is moved to PQ and its reactive to QMin (if low voltage) or to QMac (if high voltage).
The enformcement of realistic voltage limit is performed only after the reactive limit outerloop is stabilized

What is the current behavior?
The Newton Raphson fails if a bus reaches a low voltage - a situation that can happen with remoted voltage control due to the PQV model.

What is the new behavior (if this is a feature change)?
The resolution if networks with stressed or inconsistent remote voltage targets is more robust.

Does this PR introduce a breaking change or deprecate an API?

• Yes
• No

This PR modifies the ACSolver API

If yes, please check if the following requirements are fulfilled

• The Breaking Change or Deprecated label has been added
• The migration steps are described in the following section

Implementers of an external AC Solver should adapt the run API. The API takes an additional argument that can disable realistic checks.
If the solver checks an unrealistic state, they should implement the new isStateUnrealisticForSolver method.

What changes might users need to make in their application due to this PR? (migration steps)
No change expected.
