Abstract(s)
Acordos internacionais como a Agenda de 2030 para o desenvolvimento sustentável, aceleraram o desenvolvimento e utilização de tecnologias de energias renováveis e de uso eficientes da energia elétrica, dentre essas as microrredes. Uma microrrede inteligente integra sistemas de geração distribuída por fontes renováveis (ou não), equipamentos consumidores e sistemas de armazenamento e gestão de energia com alta capacidade de monitorização e controlo, a qual pode estar conectada ao sistema elétrico de energia ou a operar em modo autônomo. Esta dissertação tem como objetivo realizar a monitorização e análise de duas microrredes inteligentes em dois edifícios de divulgação de ciência, designadamente a Casa da Seda e o Posto Aquícola de Castrelos, na cidade de Bragança, Portugal.
As microrredes inteligentes apresentadas neste trabalho são ligadas à rede elétrica e possuem potencial de geração fotovoltaico e hídrico, sistema de gestão e armazenamento de energia em baterias. Após a instalação das microrredes, realizou-se a monitorização e análise de seu desempenho. Na microrrede inteligente da Casa da Seda, após onze meses de operação, mostrou-se que o autoconsumo proposto foi devidamente implementado e que o sistema implementado possibilitou uma taxa de autonomia de 45% em termos anuais. Já a microrrede inteligente do Posto Aquícola de Castrelos, apesar de pouco de tempo operação (treze dias) já mostrou que o autoconsumo está a ser implementado e que tem bom potencial para que a taxa de autonomia seja elevada.
Portanto, as microrredes inteligentes analisadas mostraram-se ser uma tecnologia que promove o uso eficiente, seguro e ambientalmente consciente da energia elétrica produzida localmente.
International agreements, such as the 2030 Agenda for sustainable development, have accelerated the development and use of renewable energy technologies and efficient use of electricity, including microgrids. A smart microgrid integrates generation systems distributed by renewable sources (or not), consumer equipment and energy management and storage systems with high monitoring and control capabilities, which can be connected to the electrical energy system or operating in an autonomous mode. This dissertation aims to carry out the monitoring and analysis of two smart microgrids in two science dissemination buildings, namely the Silk House and the Castrelos Aquaculture Center, in the city of Bragança, Portugal. The smart microgrids presented in this work are connected to the grid and have the potential for photovoltaic and pico hydro generation, a management system, and energy storage in batteries. After the installation of the microgrids, their performance was monitored and analyzed. In the smart microgrid of Silk House, after eleven months of operation, it was shown that the proposed self-consumption was properly implemented and that the implemented system allowed an autonomy rate of 45% in annual terms. Already the smart microgrid of the Castrelos Aquaculture Center, despite the short time of operation (thirteen days) has already shown that self-consumption is being implemented and that it has good potential for the autonomy rate to be high. Therefore, the analyzed smart microgrids proved to be a technology that promotes the efficient, safe, and environmentally conscious use of the electricity produced locally.
