Abstract

To obtain a stable energy supply and manage PhotoVoltaic (PV) systems efficiently, satellite imagery methods are being developed to estimate the solar PV potential. This study analyzed trends in the use of satellite imagery in solar PV and solar irradiation estimation technology. The imaging technology is used to produce solar energy resource maps. The trend analysis showed that the level of solar PV technology in Korea is 30% below that of advanced countries. It is impossible to raise such low-level technologies to the levels of advanced countries quickly. Intensive research and development is the only way to achieve the 80% technology level of advanced countries. The information produced in this process can contribute to the management of solar power plants. A valid technology development strategy would be to obtain effective data that can be used for fieldwork. Such data can be produced by estimating solar irradiation very accurately with several-hundred-meter resolution using Communication, Ocean, and Meteorological Satellites (COMS) and next-generation GEO-KOMPSAT 2A, developing core technologies for short- and medium-term irradiation prediction, and developing technologies for estimating the solar PV potential.

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.
