Estudo comparativo em diferentes bases de dados de uma simulação assistida por software de modelagem de uma usina solar fotovoltaica

Abstract

The study begins with the introduction of basic concepts about photovoltaic generation, photovoltaic systems and all the components that compose it, also analyzing how meteorological bases and typical meteorological years are formatted that are used as a basis for solar energy simulations. Then, a 3D modeling of a solar plant installed on the ground was carried out, in the city of Aquiraz-Ce, with 75.9kWp of power and then performed 8 simulations varying the database. After modeling, the results were compared with the actual values obtained at the plant. The results ranged from -5.41% below the generation to 8.59% above the expected value. The database with the highest accuracy being the CRESESB reaching the value of 0.36% of difference. At the end of this work, the results reveal about the databases used that: the CRESESB and SOLCASTTMY databases are in agreement with a small margin of error (below 2%), while PVGIS, NREL are far from the desired value. (above 5%), thus facilitating the choice of which database to use in further studies on the generation of photovoltaic plants in Ceará.
