Investigation on Promising Offshore Wind Farm Sites and their Wind Farm Capacity Factors considering Wake Losses in Korea

초록

A commercial CFD code with the national wind atlas of Korea was used to investigate promising offshore wind farm sites and their developable capacities or implementation potential in Korea. The sea around Korea was divided into nine analysis regions with dimensions of 200 km x 200 km, and wind resource maps having a resolution of 500 m x 500 m were constructed using three years of national wind atlas data. Factors including water depths, distances from the grid, and minimum capacity of a wind farm as well as the wind power density were used to select promising offshore wind farm sites in Korea. A total of ten sites were selected after excluding military areas of operation, fisheries and national parks. The developable capacity of the promising wind farm sites were calculated using a commercial wind farm design tool with the wind resource maps obtained from the commercial CFD code by considering wake effects. The total developable capacities of the promising wind farm sites were estimated to be about 6.57 GW and the capacity factors ranged from 26.1% to 30.5%.
