Especificação e desenvolvimento de um sistema eletrônico de gerenciamento da geração e consumo de energia em uma planta fotovoltaica off-grid

Abstract

The generation of energy from renewable sources has become a topic of research and technological application of worldwide interest. The aim is to optimize the generation and use of these energies. This final project in Electronic Engineering is focused on energy generation through hybrid photovoltaic plants, particularly operating disconnected from the public electric grid (i.e., off-grid). The project proposes a management system for hybrid plants whose purpose is to regulate the power of the loads based on the energy availability of the plant. This system will be implemented in a photovoltaic energy plant at UTFPR in Curitiba, using a cRio hardware architecture from the National Instruments LIT/CITEC laboratory. The control development was done in the LabVIEW language. Based on the monitored signals from the plant, the system controls the energy consumption of the loads in order to optimize the availability of energy for these points of consumption.
