Abstract
The installed capacity in centralized solar photovoltaic generation in Brazil corresponds to 4.5 GW, according to ANEEL data from December 2021. The Northeast region is home to around 72% of the centralized photovoltaic projects in the country, due to its high potential. In this region, Bahia (28.5%) and Piauí (22.5%) stand out. However, for the development of solar projects, it is necessary the study the resource in multiple sites that make it possible to know its regional availability and temporal variability to enhance the performance of the installed technology, since the technical and economic feasibility of a system for harnessing solar energy depends on these factors. In this context, the present work aims to estimate the global solar irradiation (GHI) and direct normal (DNI) in the region of Vale São Francisco da Bahia using the WRF-Solar model. The horizontal spatial resolution of the model was 1 km and the simulation period was the month of October 2016. The performance of the model was evaluated with hourly data of GHI and DNI estimated by satellite images from the GOES series (Geostationary Operational Enviromental Satellites) from the INPE database. The simulations were satisfactory through statistical analysis between simulated and observed hourly data for GHI and DNI, respectively, with a normalized squared error of 0.03 and 0.12, fractional deviation of -0.003 and -0.31, coefficient of correlation of 0.94 and 0.95 and factor of 2 of 0.91 and 0.99. In addition, the results showed that the model is able to satisfactorily represent the series with a weekly average, as well as the DNI estimates had better results. Finally, the results allow us to conclude that the WRF-Solar model, which represents the state of the art in mesoscale modeling, presented good performance in the simulation of solar irradiation and presents great potential for operational, research and technological development purposes.
