Abstract
The reduction of the power generation cost is a major factor in the main power generation of renewable energy, and the frequency distribution of the average wind speed greatly influences the power generation in the environmental conditions surrounding wind power generation. It has been pointed out that in offshore wind power generation, which is currently attracting attention in Japan, the effects of the topography are not small, as practical use is advanced from coastal areas with shallow depths. Therefore, in this study, we compared the wind observation record at a lighthouse in the coastal and its wind turbines with hub height of more than 60 m, and examined the influence of the topography based on the wind conditions simulation results by MASCOT. By applying these results, we will contribute to the examination of offshore wind candidate sites in the future.
