Characteristics of wind power generation in Jeju Island

Abstract

Jeju Island has implemented “Carbon-Free Island, Jeju by 2030” plan since 2012. The main means to realize it to be a carbon-free region is penetration of electric vehicles and renewable energies. In this paper, we summarized status and characteristics of Jeju Island’s wind power generation and confirmed change of wind resource in the island according to climate change. The yearly averaged wind speed decreased by 0.05 m/s rate over the last 17 years. A new wind resource map for Jeju Island was suggested and was produced by using the economic method that uses freely the weather data measured by the meteorological office. We were able to increase the exactness of the map by using the real weather data of so many locations obtained from the 37 automatic weather measuring systems instead of artificial satellite weather data.
