Determinación de zonas de mayor potencial solar usando el modelo global System Advisor Model (SAM), en la provincia de Chimborazo

Abstract

For the implementation of solar thermal plants in the future within the province of Chimborazo. There had not been detailed studies on these usable areas, in terms of direct normal irradiation (DNI). This research aimed to identify areas of greatest solar potential in the province of Chimborazo, using the System Advisor Model (SAM). The methodology used was a quantitative approach, and a non-experimental cross-sectional design, since the amount of direct normal irradiation (DNI) was described in a specific period of time of 6 years (2014 to 2020); the study population was province, so the area close (approximately <2km) to its installed terrestrial meteorological stations was considered, and in turn the national solar radiation database (NSRDB) was used where descriptive statistics were used to correlate and validate global irradiation variables horizontal (GHI) (from terrestrial data) and direct normal irradiation (DNI) (from satellite data) subsequently said data was simulated in the System Advisor Model (SAM). Using this methodology, it was determined that the areas with the highest solar potential with direct irradiation greater than 3.5 kWh/m2/day were the areas near the Tunshi, Tixán, Espoch and Quimiag stations. In this context, it was concluded that the areas with the greatest solar potential were Tunshi, Espoch, Tixán and Quimiag. Their respective meteorological conditions were also described, thus, the higher the altitude, the greater the direct solar radiation received in these areas. However, they also influence meteorological factors such as wind speed, temperature and relative humidity with slight variations in their trends during the 6-year period.
