DNV is assisting KEPCO (Korea Electric Power Corporation) Research Institute in the development of a long-term offshore power grid plan to deliver renewable offshore wind power to South Korea. The project is scheduled for completion by mid-2025. South Korea has set a goal of deriving 20% of its power from renewable sources by 2030, and wind energy is a rapidly growing industry, supported by the policy ambition to grow the wind share of the country’s energy mix from 1% in 2015 to 6% by 2030.
KEPCO aims to expand its network along the western coast of South Korea and deliver power from high-capacity renewable Offshore Wind Farm (OWF) sites to key demand centres in the country’s capital, Seoul. DNV’s detailed work scope includes collecting and analysing offshore wind farm data; preparing a conceptual design of the power collecting element (bus) for the OWF; drafting functional specifications for AC/DC converter stations; analysing the impact of the offshore DC system to the onshore AC system; reviewing the relevant environmental and code limitations for the network routing and delivering a detailed design of the multi-terminal DC system including the converter topology, location and control/operational strategy.
