Single-Course English 5 ECTS

Offshore wind grid connection and high-voltage DC (HVDC) transmission

Overall Course Objectives

Give students advanced competences for the analysis and design of grid connection and integration of offshore wind power, including technology for HVDC transmission and offshore grids, and control and operation principles for converters and HVDC transmission and grids.

See course description in Danish

Learning Objectives
