Abstract(s)
O principal objetivo é desenvolver uma metodologia de projeto e dimensionar equipamentos
para implementação de um sistema fotovoltaico com enquadramento de autoconsumo aplicado
em um estudo de caso. Esse trabalho tem em vista avaliar cenários com projetos de sistemas
fotovoltaicos distintos obtendo informações como a produção energética e a fração renovável
consumida no ponto de consumo atrelado a um estudo de viabilidade econômica para cada
cenário projetado. Para obter uma escolha entre os cenários foram realizados três casos
comparativos com a finalidade de apresentar o melhor perfil de projeto para o estudo de caso.
Foi feito um sucinto estado da arte das tecnologias que compõem um sistema fotovoltaico,
abordando seus princípios de operação para a produção de energia elétrica. Em seguida, é
apresentado uma abordagem do conceito de autoconsumo aplicado a tecnologia fotovoltaica e
os enquadramentos legislativos que permeiam a tecnologia em Portugal.
Por fim, é desenvolvida uma metodologia que aborda os princípios de dimensionamento dos
elementos que compõem um sistema fotovoltaico, e a partir dessa metodologia aplicada ao
estudo de caso, são propostos cenários com distintos enquadramentos legislativos e diferentes
disposições de módulos fotovoltaicos quanto a sua inclinação e distribuição no edifício. Desse
modo, é possível realizar a avaliação através de resultados através de indicadores econômicos
e produção energética utilizando algumas ferramentas de cálculo e simulação como o simulador
PVGIS, o software MATLAB, a folha de cálculo Excel e o programa HOMER Pro.
The main objective is to develop a design methodology and design equipment for the implementation of a self-consumption framing photovoltaic system applied in a case study. This work aims to evaluate scenarios with different photovoltaic systems projects obtaining information such as energy production and renewable fraction consumed at the point of consumption linked to an economic feasibility study for each projected scenario. To obtain a choice between the scenarios, three comparative cases were performed to present the best project profile for the case study. A succinct state of the art of the technologies that make up a photovoltaic system was made, addressing its operating principles for the production of electricity. Next, we present an approach to the concept of self-consumption applied to photovoltaic technology and the legislative frameworks that permeate the technology in Portugal. Finally, a methodology is developed that addresses the principles of sizing of the elements that make up a photovoltaic system, and from this methodology applied to the case study, scenarios with different legislative frameworks and different provisions of photovoltaic modules regarding their inclination and distribution in the building Thus, it is possible to perform the evaluation through results through economic indicators and energy production using some calculation and simulation tools such as PVGIS simulator, MATLAB software, Excel spreadsheet and HOMER Pro program.
