Este trabalho visa aprimorar o projeto de um sistema fotovoltaico dentro de uma Comunidade de Energia (CER) constituída pelos edifícios do Instituto Politécnico de Bragança (IPB), situado na região Nordeste de Portugal. O estudo concentra-se no autoconsumo coletivo no Campus do Instituto Politécnico de Bragança, onde os edifícios irão compor a futura comunidade de energia, em conformidade com a legislação atual. Para dimensionar de maneira correta o sistema e atender à demanda diária da comunidade de energia, diversos fatores foram considerados, incluindo as coordenadas geográficas do local de instalação, o grau de incidência solar na região e as faturas de energia. O objetivo principal é garantir que o gerador fotovoltaico
satisfaça de forma eficaz o consumo local, buscando atingir o maior índice de autoconsumo possível, em conformidade com as exigências do concurso que fundamenta este trabalho.
O projeto em análise engloba 14 Códigos de Ponto de Entrega (CPE), totalizando um consumo agregado de 2.381.640,4kWh/ano, o que se traduz em um custo de 442 985,04€/ano, considerando os custos previstos para a energia ativa em 2024. A geração fotovoltaica será distribuída por 4 Unidades de Produção para Autoconsumo (UPACs) com uma potência instalada de 500kWp, que fornecerão energia elétrica a toda comunidade, sendo os postos de geração à Escolas Superiores de Educação (ESE), Agrária (ESA) e de Tecnologia e Gestão (ESTIG), sendo a Escola Superior Agrária subdividida em ESA1 e ESA2.
O dimensionamento do sistema foi conduzido utilizando programas especializados, tais como PVGIS, PVSYST e Sunny Designer, com o intuito de obter resultados próximos à realidade. A produção estimada pela comunidade de energia é de 731.182kWh/ano, resultando em uma taxa de autoconsumo de 85,3%, estima-se uma redução no consumo de energia da ordem de 30%.
This work aims to enhance the design of a photovoltaic system within a Community of Energy (CER) formed by the buildings of the Polytechnic Institute of Bragança (IPB), located in the Northeast region of Portugal. The study focuses on collective self-consumption at the campus of the Polytechnic Institute of Bragança, where the buildings will constitute the future energy community, in compliance with current legislation. To dimension the system correctly and meet the daily demand of the energy community, various factors were considered, including the geographical coordinates of the installation site, the degree of solar incidence in the region, and energy bills. The main objective is to ensure that the photovoltaic generator effectively meets local consumption, aiming to achieve the highest possible self-consumption rate, in accordance with the requirements of the competition that underlies this work. The project under analysis includes 14 Point of Delivery Codes (CPE), totaling an aggregated consumption of 2,381,640.4 kWh/year, translating to a cost of 500,000.00€/year, considering the projected costs for active energy in 2024. The photovoltaic generation will be distributed among 4 Units of Production for Self-Consumption (UPACs) with an installed capacity of 500 kWp, providing electrical energy to the entire community. The generation stations are allocated to the Higher Schools of Education (ESE), Agrarian (ESA), and Technology and Management (ESTIG), with the Agrarian Higher School subdivided into ESA1 and ESA2. The sizing of the system was conducted using specialized programs such as PVGIS, PVSYST, and Sunny Designer, with the aim of obtaining results close to reality. The estimated production by the energy community is 731,182 kWh/year, resulting in a self-consumption rate of 85.3%. A reduction in energy consumption of approximately 31% is anticipated.
