Hoseo University, the Chungcheongnam-do Energy Research Institute, and the Asan City Council joint research team received an excellence paper award at an international academic conference for research that comprehensively analyzed the power generation potential and environmental and site conditions of wind power candidate sites in the Dangjin and Asan regions of Chungcheongnam-do.
The joint research team announced that it received the excellence paper award at the International Conference on Electrical Facilities and Information Technologies 2026 (ICEF 2026), held at Chiang Mai University in Thailand from the 18th to the 21st, for the paper "Feasibility Assessment of Wind Power Generation Candidate Sites in Dangjin and Asan Considering Environmental Standards for Offshore Wind Preliminary Districts."
The research involved joint participation by researchers Ji Min-gu, Lee Woo-seok, and Gu Kyung-wan from Hoseo University; researchers Lee Jeong-nam and Kim Mi-young from the Chungcheongnam-do Energy Research Institute; and council members Yun Won-jun and Kim Eun-a from the Asan City Council.
ICEF is an international academic conference hosted by the Electrical Facilities Division of the Korean Institute of Electrical Engineers. This year it was held under the theme "Next Generation Advanced Electric Facility and Information Technology," and the research team presented its findings through a poster session on the 20th.
Analysis of Three Wind Power Candidate Sites
The research was conducted on three wind power candidate sites: Asan onshore and nearshore 72MW, Asan offshore 200MW, and Dangjin offshore 128MW in Chungcheongnam-do. Using WindPRO, a wind farm design and analysis program, the team calculated expected power generation and applied environmental and site criteria that should be considered in the process of selecting offshore wind preliminary districts to compare the feasibility of each candidate site.
Analysis results showed that the Asan onshore and nearshore 72MW candidate site had an annual net power generation (Net AEP) of 91.4GWh and a capacity factor of 14.5%. The Asan offshore 200MW candidate site had an annual net power generation of 402.2GWh and a capacity factor of 23.0%, showing the highest power generation among the three candidate sites. However, wake loss from wind interference between turbines was analyzed at 19.3%, indicating that turbine layout optimization is needed.
The Dangjin offshore 128MW candidate site recorded an annual net power generation of 260.8GWh and a capacity factor of 23.3%. It had the highest capacity factor among the three candidate sites, and with wake loss at 14.2%, lower than the Asan offshore candidate site, it was evaluated as relatively favorable in terms of power generation efficiency relative to installed capacity.
Environmental and Site Condition Assessment
Along with power generation analysis, the research team incorporated into the evaluation site conditions that affect actual project implementation, including fishing activities and tidal flats, maritime traffic, port operations, landscape, military and navigation zones, submarine cables and grid connection, and community and fishery worker acceptance.
Based on this, the team concluded that the Dangjin and Asan offshore wind candidate sites should be approached as "conditionally reviewable preliminary districts" requiring additional examination of environmental and site constraints and stakeholder acceptance based on power generation potential, rather than being judged as areas ready for immediate development.
The research is expected to enable more precise feasibility assessment of the offshore wind candidate sites in the Dangjin and Asan regions and derivation of preliminary district priorities.
Consecutive Recognition and Future Plans
With this award, the research team has received the excellence paper award at ICEF for two consecutive years. At ICEF 2025 held in Phu Quoc, Vietnam last year, the team presented "Current Status and Challenges for Sustainable Development of Wind Power in Vietnam" and received the excellence paper award.
While last year's research addressed the current state of Vietnam's wind power market and tasks for sustainable expansion, this year the research scope was specified by analyzing both power generation and environmental and site conditions for actual wind power candidate sites in Chungcheongnam-do. In particular, with the Asan City Council participating in the research alongside Hoseo University and the Chungcheongnam-do Energy Research Institute, academic analysis was combined with regional policy and on-site perspectives.
The research team plans to conduct additional work including overlapping analysis using GIS of shipping routes, fishing rights, tidal flats, protected areas, submarine cables, and grid connection points; on-site wind condition verification; turbine layout optimization; grid connection scenario analysis; and community and fishery worker acceptance surveys.
