태양에너지 시스템에 적합한 표준기상데이터의 제작과 일사량 데이터 분석

The typical meteorological year (TMY) data reflect the long-term meteorological characteristics in a specific location and thereby serve as critical input in solar energy simulations. On the other hand, domestically, only a few of studies have been dedicated to TMY data with reliable solar irradiance and their analysis. We generated new TMY data of 10 major cities using the meteorological data from 1991 to 2010 measured by the Korea Meteorological Administration (KMA). To generate TMY data suitable for solar energy systems, we applied a better solar decomposition model for direct normal irradiance (DNI) and the generation method by National Renewable Energy Laboratory (NREL). We analyzed the new TMY solar irradiance data by comparisons with the 20-year long-term means, data provided by Korean Solar Energy Society (KSES), and data included in the TRNSYS and PVsyst programs. Finally, we demonstrated that the TMY data proposed in this study represent the solar irradiance more appropriately.
