This chapter provides an overview on the main challenges encountered during the interconnection of marine energy farms to the onshore electric power system. It explains how less technologically mature marine energy converters (MECs), such as wave and tidal ones, are normally integrated into distribution systems, and potentially cause power quality problems. Then it shows how system level issues arise when larger offshore installations, such as offshore wind farms, are interconnected to power transmission systems. The presentation is complemented by illustrative test cases.
