Terminal
Class  
Name: ConverterDCSides
All converters' DC sides linked to this point of common coupling terminal.
Name: PccTerminal
Point of common coupling terminal for this converter DC side. It is typically the terminal on the power transformer (or switch) closest to the AC network. The power flow measurement must be the sum of all flows into the transformer.
