Measurements and reanalysis data on wind speed and solar irradiation from energy generation perspectives at several locations in Poland

摘要: Energy system research requires input data with high temporal and spatial resolution. However, the measurements performed in meteorological stations are only available for selected locations. Currently a growing number of papers on small large-scale power systems utilizes coming from satellite various reanalyses. Although many authors aimed at comparing sources irradiation wind speed there is lack such studies, which compare both resources simultaneously same location. In consequence, studies entirely based satellite/reanalysis may not be representative. this paper 15 locations Poland have been where National Institute Meteorology Water Management performs continuous speed, temperature global horizontal surface. Hourly time series were obtained year 2012 2013. The renewable converted into electrical energy, considering performance typical PV panels turbines. findings study as follows: solar radiation (CAMS ERA5) shows good agreement ground measurements, hourly values coefficient correlations greater than 0.9; individual energy yield can differ by up to 9% but average (all locations) simulated higher less 0.5%; simulations showed large variability results differences capacity factors reaching percentage points.
