Description
Summary:The present investigation shows the influence of the variation of solar radiation and temperature on the generation of electrical energy in a photovoltaic system connected to the grid, considering the current NEC-11 regulations of the country. To address the problem, real data from the Ventana’s canton, Los Ríos province, Ecuador, are considered, and the Monte Carlo method is used to complete the missing data from the radiation and temperature measuring instruments. Next, we develop a simulation in MATLAB Simulink that takes into account the maximum transfer power function, followed by another simulation in PVsyst to ascertain the system’s energy production capacity. The results show that the electrical grid supplies 60.44 % of the demand, while the photovoltaic system contributes 39.56 %. Finally, the analysis of electrical energy generation, considering fluctuating solar radiation and temperature data versus keeping this parameter constant, shows a 0.79 % increase in generation by the photovoltaic system.
