Simplified generic wind turbine models for HVDC Offshore ProjectsModel example: full scale converter wind turbine generator(1/3)
Detailed model complex focus on system behaviour computational-intensive scaling problematic
Controlled voltage source simple focus on grid behaviour low computational effort scaling simple
Modeling approach:
