Abstract(s)
Neste trabalho será efectuada a análise energética de uma habitação com necessidades energéticas quase nulas (nZEB), com a integração de um veículo elétrico e a utilização de Micro-grids e Smartgrids para obtenção de melhorias de consumo e eficiência energética, recorrendo ao desenvolvimento de uma ferramenta de simulação numérica de gestão de energia. A metodologia de análise irá basearse nos impactos da introdução de um veículo de mobilidade elétrica na eficiência da habitação, considerando vários cenários alternativos a um modelo de base calculado, onde serão considerados os consumos elétricos associados ao uso de equipamentos domésticos, assim como os consumos elétricos dos sistemas de climatização e iluminação e o contributo do sistema de produção de energia elétrica renovável implementado. Serão analisados, com a aplicação desta ferramenta, quais os seus impactos no consumo energético da habitação, para os demais cenários supra mencionados, assim como a autossuficiência atingida pelo sistema, o comportamento do veículo elétrico na obtenção destes resultados, o custo energético associado às necessidades energéticas e o impacto na classificação energética da habitação, de acordo com a legislação aplicada, e para todas as tarifas energéticas praticadas em Portugal de acordo com o mercado regulado. A implementação desta ferramenta e de vários cenários permitirá a redução drástica dos consumos energéticos da habitação, registando uma diferença de 240% entre o cenário mais eficiente e o cenário inicial, resultando numa diminuição do custo do uso de energia em 126% e um incremento na classificação energética da habitação.
In this essay, the energy analysis of a house with near zero energy requirements (nZEB) will be conducted, with the integration of an electric vehicle and the use of Micro-grids and Smart-grids to obtain improvements in consumption and energy efficiency, using the development of a numerical simulation tool for energy management. The analysis methodology will be based on the impacts of the introduction of an electric mobility vehicle on the efficiency of the dwelling, considering several alternative scenarios to a calculated base model, where the electric consumption associated with the use of domestic equipment will be considered, as well as the electric consumption of the air conditioning and lighting systems and the contribution of the implemented renewable electrical energy production system. With the application of this tool, we will analyse the impacts on the house energy consumption for the other scenarios mentioned above, as well as the self-sufficiency achieved by the system, the behavior of the electric vehicle in obtaining these results, the energy cost associated with the energy needs and the impact on the house energy rating, according to the applied legislation, and for all the energy tariffs practiced in Portugal according to the regulated market will be analysed The implementation of this tool and of several scenarios will allow to drastically reduce the energy consumption of the house, registering a difference of 240% between the most eficiente scenario and the initial scenario, resulting in a 126% decrease in the cost of energy use and an increase in the energy rating of the house.
