Offshore wind delivery system technology assessments and performance evaluation

In connection with the DOE funded National Offshore Wind Energy Grid Interconnection Study (NOWEGIS), assessments for offshore wind delivery systems are made for different technologies (HVAC vs. HVDC) and topologies (radial vs. backbone vs. grid). Further, the performance and system impacts of the various options are assessed from a steady-state perspective using power flow analyses under normal system conditions and contingency conditions. Observations are made based on the findings and general knowledge of typical system operations.
