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

What kind of change does this PR introduce?
A new parameter, voltageRemoteControlRobustMode is introduced. With value true by default.
When the robust mode is set to true,

• The enforcement of realistic voltage limit is performed only after the reactive limit outerloop is stabilized

the reactive limit outerloop is modified as follow:

If the bus of a generator with remote voltage control on , and reactivie limits, is approaches the realistic voltage limit:
- If the bus is outside its reactive limits, it is move PQ (as usual) and its voltage is set to 1pu for the next NR run
- If the bus is inside its reactive limites, it is removed from voltage control (and Q is set to initial targetQ). Its voltage is set to 1pu for the next NR run.

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)?
With voltageRemoteControlRobustMode set to true (the default value) the resolution of networks with stressed or inconsistent remote voltage targets is more robust.

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

• [] Yes
• [ X ] No

Some minor remarks on the code and I did some typo fix.

[jeandemanged]

ok for me, except one API design topic (AcSolver) that needs to be though about maybe.
Otherwise just minor comments.

[jeandemanged]

Thank you, just minor polishing to do.

Please also update the PR description:

• not a breaking change anymore
• mention the new parameter and its default value
