인공위성영상 예측기법을 적용한 태양광에너지 이용가능성 평가에 관한 연구

Images taken by geostationary satellite may be used to estimate solar irradiance fluxes at earth's surface. It is based on the empirical correlation between a satellite derived cloud index and the irradiance at the ground. For the validation, estimated solar radiation fluxes are compared with observed solar radiation fluxes at 16 sites over the Korean peninsular from January 1982 to December 2004. Estimated solar radiation fluxes show reliable results for estimating the global radiation with average deviation of -7.8 to +7.0 % from the measured values and the yearly averaged horizontal global insolation of Korean peninsula was turned out to be 3.56 kW/m²/day.
