The national goal of wind energy dissemination has to be determined rationally based on technically available wind resource potential. For an accurate and scientific estimation of wind resource potential, a wind map is requisite. This paper introduces the national wind map of Korea established by numerical wind simulation. Therefore, quantification of national wind resource potential is now possible and is anticipating to be used as a core index for policy and strategy building of wind energy dissemination and technology development.

The wind resource potentials of South Korea are estimated as preliminary stage using the national wind map which has been being established by numerical wind simulation and GIS (Geographical Information System) exclusion analysis. The wind resource potentials are classifying into theoretical, geographical, technical and implementation potentials and the calculation results are verified by comparing to other countries' potentials. In GIS exclusion, urban, road, water body, national parks and steep slope area are excluded from onshore geographical potential while water depth and offshore distance from the shoreline are applied s offshore exclusion conditions. To estimate implementation potential, dissemination records of European countries are adopted which is about 1/8 of geographical potential.

The implementation potential of South Korea would correspond 12.5GW which is 1.7 times of the national wind energy dissemination target until 2030.

Geographic information system (GIS) based renewable energy resource map including potential analysis can play a crucial role not only to develop the national plan for renewable energy deployment but also to make strategic investment decision in the private sector. Korea Institute of Energy Research (KIER) has been developing domestic maps about several resources such as solar, wind, hydro, biomass, and geothermal, as well as conducting research on methodologies for potential analysis. Furthermore, the institute is trying to transfer related technologies and know-how to foreign countries, recently. In this context, the main purpose of this study is to introduce the business model of renewable energy resource map. From the value chain analysis, we focus on the government-side market in foreign countries, such as the development of the national level renewable energy resource map and the support of the national renewable energy plan. For about 180 countries, we segment the customers according to the consideration of economic capacity, renewable energy resource capacity, existence of renewable resource map, current portion of renewable energy facility capacity, and renewable energy policies, and we conclude that the target customers are non-Organization for Economic Co-operation and Development (non-OECD) countries or some OECD countries, their per capita GDP are under the average among OECD countries, that do not have renewable resource map yet. We segment the target customers into four groups, and suggest different strategies for market positioning and financing strategy based on Strengths, Weaknesses, Opportunities, Threats (SWOT) analysis. This study can help to develop the business strategy about the development of renewable energy resource map in foreign countries.

태양열 집열판을 이용한 가온재배 실태를 조사 분석하고 그에 따른 문제점을 도출하여 해결방안을 모색, 향후 자연에너지 이용 기기제작 및 사용의 기초자료를 제공하고자 태양열 집열판을 이용한 20농가를 조사한 결과, 설치 비용은 18백만원/20a정도 소요되었으며, 주 재배작목은 토마토(30%)와 화훼(40%)였고, 포도, 고추, 오이, 상추 및 딸기 등도 일부 재배하고 있었다. 태양열이용 정보는 대부분 지도기관에서 얻고 있었으며, 연료절감 효과가 20%미만이라고 응답한 농가가 75%로 지도기관에서 조사한 대부분 20%이상과는 차이가 있었다. 연료절감 효과에 비하여 시설비의 과중과 시공업체의 기술부족이 문제점으로 나타나 이의 보완이 필요하였다.

Many countries have recently been expanding efforts for low-carbon global economy to solve the problem of global warming. Development and research for various types of new reusable energy is on the rise throughout the world. The most promising source of energy is the solar photovoltaic energy and the government take an initiative to establish both short-term and long-term policies to develop the solar energy potential resource map. The solar energy and industrialize area researched by GIS methods for optimum site for solar power transfer system. This study attempts to address the hot issue of the development and suitability of the solar photovoltaic energy site using GIS spatial analysis. We need to analyze and describe the solar technology, green energy policies and the energy market trend of the field.

The resource potentials biomass resources of South Korea are estimated as Preliminary stage using relevant National statistics. Biomass resources possibly be collected, used and converted to bioenergy in Korea are forest biomass, agricultural residue, livestock manure and municipal solid wastes. The potential biomass resources are classifying into total potential, available potential and technically feasible biomass resources, Total potential biomass resources in Korea are estimated to be around 140million tons of oil equivalent (toe). Available potentials are estimated to be around 11million annually. The technically feasible biomass resources with current technologies are estimated to be 2.3million toe annually. These estimated values are the minimum of all potentials since they are all estimated from explicit statistics. Although actually there exist huge amount of biomass on the land as well as in the sea, potential resources for bioenergy are believed to be limited. The potentials are to be inclosed with the improvement of bioenergy technologies.

Commercial wind farm design tools and the national wind map are used to determine the implementation potential of offshore wind power in Korea in this study. For this, the territorial waters of Korea were divided into nine analysis regions and a commercial CFD code was used to obtain wind resource maps at 100m A.S.L. which is the hub height of a 5MW wind turbine used in this study. With the wind resource obtained, factors including water depth, distance from substations, minimum and maximum capacity of a wind farm, distance between turbines and wind farms were considered to determine wind power potential. Also, the conservation areas, military zones, ports, fishing grounds, etc. were considered and excluded. As the result, a total capacity of 6,720 MW was found to be the implementation potential and this corresponds to $3.38MW/km^2$ in API. Also if the distance from the substation is not considered, the potential increased to be 10,040 MW. This offshore wind farm potential is considered enough to satisfy the target of wind farm capacities in the 7th national plan for electricity demand and supply.

Promising onshore wind farm sites in Gangwon province of Korea were investigated in this study. Gangwon province was divided into twenty five simulation regions and a commercial program based on Reynolds averaged Navier-Stokes equation was used to find out wind resource maps of the regions. The national wind atlas with a period 2007-2009 developed by Korea institute of energy research was used as climatologies. The wind resource maps were combined to construct a wind resource map of Gangwon province with a horizontal spatial resolution of 100m. In addition to the wind resource, national environmental zoning map, distance from substation, residence and automobile road, Beakdudaegan mountain range, terrain slope, airport and military reservation district were considered to find out promising wind farm sites. A commercial wind farm design program was used to find out developable wind farm capacities in promising wind farm site with and without excluding environmental protection regions. The total wind farm capacities with and without excluding the protection regions were estimated to be 46MW and 598MW, respectively, when a 2MW commercial wind turbine was employed.

세계적으로 자국의 에너지 수급의 안정성을 도모함과 동시에 태양광 발전시스템의 효율적인 운영을 위한 위성기반 태양광 발전가능량 산출기술 개발이 중요한 관심사로 주목받고 있다. 본 연구는 위성기반 일사량 산출기술과 태양광 발전가능량 산출기술에 대한 동향을 분석하고 관련기술 개발 전략을 제시하는데 그 목적을 둔다. 동향 분석 결과, 우리나라의 태양광 발전가능량 산출에 대한 전반적인 기술 수준은 선진국 대비 30% 이하로 아주 미미한 수준이며 이는 태양광 자원지도 제작에 국한되어있다. 이러한 기술 수준을 단시간 내에 선진국과 대등하게 끌어올리는 것은 거의 불가능할 것이다. 따라서 집중적인 연구개발을 통해 선진국 대비 80% 수준의 기술 수준을 달성하여 주요한 정보를 제공하여야 만이 실제 현업에서의 태양광 발전소 운영에 기여할 수 있을 것이다. 즉 가능한 빠른 시간 내에 현재 운영되고 있는 COMS 뿐만 아니라 차세대 고해상도 정지궤도기상위성 자료를 이용한 수백 m 급 고정밀 일사량 상세화 기술과 단기 또는 중기 일사량 예측을 위한 핵심기술이 우선적으로 확보되어야하며, 이후 위성기반 태양광 발전가능량 산출기술을 개발함으로써 현업에서 활용될 수 있는 정보를 제공함이 현실적으로 타당한 기술개발 전략일 것이다.
