초록
Typical meteorological year (TMY) data consist of hourly values of solar radiation and meteorological elements over a 1year period. This reflects the long term meteorological characteristics because it is derived from a long term meteorological database. The data were produced by applying the Sandia method and weighting factor of National Renewable Energy Laboratory (NREL) bynew and renewable energy resource center in Korea Institute of Energy Research (KIER), and it was registered as the qualifiedreference standards in 2015. The reliability of the solar radiation is important as weighting factor of the solar radiation in the TMY datais 50%. The hourly global horizontal irradiance (GHI) among the solar radiation was provided by Korea Meteorological Administration(KMA), and direct normal irradiance (DNI) was predicted by applying Reindl-2 model.[3] The uncertainty of the DNI is higher than theexperimental value as it is a predicted value. The GHI, extra-terrestrial radiation, and zenith angle were surmised as the principalfactors of uncertainty. The uncertainty on the zenith angle was highest among the 3 factors. The procedure of the uncertaintyevaluation obeyed the guide to the expression of uncertainty in the measurement (GUM).[8] The uncertainty on the DNI of TMY datain Daejeon was calculated and analyzed in this paper.
Abstract
Typical meteorological year (TMY) data consist of hourly values of solar radiation and meteorological elements over a 1year period. This reflects the long term meteorological characteristics because it is derived from a long term meteorological database. The data were produced by applying the Sandia method and weighting factor of National Renewable Energy Laboratory (NREL) bynew and renewable energy resource center in Korea Institute of Energy Research (KIER), and it was registered as the qualifiedreference standards in 2015. The reliability of the solar radiation is important as weighting factor of the solar radiation in the TMY datais 50%. The hourly global horizontal irradiance (GHI) among the solar radiation was provided by Korea Meteorological Administration(KMA), and direct normal irradiance (DNI) was predicted by applying Reindl-2 model.[3] The uncertainty of the DNI is higher than theexperimental value as it is a predicted value. The GHI, extra-terrestrial radiation, and zenith angle were surmised as the principalfactors of uncertainty. The uncertainty on the zenith angle was highest among the 3 factors.
