Enhance load flow on AC-DC networks to support symetrical configuration #1365
Description
Describe the current behavior
#1302 introduces load flow capacity on a network with the detailed DC model. However each DC component must have an explicit DcGround which is not the case for a symetrical scheme.
Describe the expected behavior
It should be possible to run a load flow on a network without DC ground. As metionned in PowSyBl-core documentation:
If no DC Ground is present, the configuration is symmetrical, in this case the converter provides internally an implicit >DC Ground and imposes:
+TargetVdc / 2 at the converter DC Node 1
-TargetVdc / 2 at the converter DC Node 2
