Comparison of methodologies for tmy generation using 20 years data for Athens, Greece

摘要: Abstract The need of accurate Test Reference Years (TRYs) for simulations has been well recognised over the years. Various methods deriving TRYs have developed, but their final results can be significantly different. In this paper, major methodologies reported in literature were applied to 20-year hourly measurements weather data from Athens, covering period 1977 1996. Seventeen produced total. basis select “best” performing TRY includes meteorological criteria (inherent selection process used by each method) and comparisons various typical energy systems (i.e. a solar water heater, building, large scale heating system with interseasonal storage photovoltaic system). Based on simulation exercise, scoring was developed applied. best found one modified Festa-Ratto method.
