The distribution of onshore wind power generation in Korea is being delayed, and location problems are considered as the primary cause. To solve this problem, an onshore wind power siting atlas has been developed, which shows the environment, forest, and resource location of onshore wind power overall. The local government may determine matters regarding the separation distance, height, and arrangement, for a specific building or structure. With the gradual spread of wind power generation, the interest of local governments has increased. The number of local governments applying the setback regulation for wind power generation has increased from 20 in 2018 to 52 in 2022, which is approximately 1.6 times in 4 years. The setback regulation has emerged as a central issue in the onshore wind power siting problem because the application targets and setback distance standard vary depending on the local government. Therefore, we evaluated the effect of the setback regulation of the local governments on the onshore wind power location. Based on the onshore wind farm siting atlas, a geographic database, containing spatial data representing 60 influencing factors and 6 setback regulation scenarios, was constructed. The onshore wind power location change according to the setback regulation was analyzed by actualizing the separation distance and analyzing scenarios.
