Display voltage control state

[flo-dup]

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

• What is the current behavior? No information displayed on voltage control

• What is the expected behavior? For voltage controlled nodes, add information to know what is the corresponding state:

  • PV node with voltage meeting target value
  • PV node with voltage not meeting target value
  • PV node which turned into PQ node

• What is the motivation / use case for changing the behavior? Better understanding of the network to help debugging
