Uma proposta de metodologia de cálculo para estimação de perdas horárias de uma usina fotovoltaica com módulos bifaciais

Abstract

Centralized generation photovoltaic plants are a reality in the national energy matrix, driven by the sale of energy in the regulated market from the Empresa de Pesquisa Energética (EPE). For the registration of projects that wish to claim the sale of energy, it is necessary to carry out a study of energy generation expectations. In this scenario, this paper proposes the analysis of a technology that has been applied in recent years to increase the efficiency of photovoltaic plants, called by bifacial modules, approaching the main points to be discused in the simulation and application of these modules in large power plants.A methodology for calculating energy losses from a photovoltaic plant to the point of injection was developed, through the calculation of hourly losses, and, as an input database for this methodology, an array of simulated photovoltaic inverters was performed in PVsyst software. Finally, the sizing of the main equipment of a photovoltaic plant using bifacial modules and the simulation of this plant are presented, proving the application of the methodology previously discussed. In this way, it is expected that the work will serve as a reference model for possible simulations of photovoltaic plants using bifacial modules, as well as for the study of the generation expectation of a large photovoltaic plant.
