Resumo(s)
As alterações climáticas que atingem, atualmente, o planeta devem-se em grande parte
ao crescente consumo energético mundial observado nos últimos 50 anos motivado pelo cres-
cimento demográfico, pela evolução tecnológica e, sobretudo, pelo aumento do consumo de
energia proveniente de fontes não renováveis. Deste modo, a transição energética com vista à
utilização e desenvolvimento sustentável dos recursos, como a integração de energias reno-
váveis no setor energético, a melhoria da eficiência energética dos setores residencial e indus-
trial e a adesão à mobilidade elétrica, assume-se como um grande pilar por forma a atingir as
metas definidas pela União Europeia e por Portugal em matéria de energia e clima.
A tecnologia solar fotovoltaica, nomeadamente por meio de Unidades de Produção
para Autoconsumo, aliada ao desenvolvimento da mobilidade elétrica surge como um possível
caminho para fazer face às alterações climáticas.
Nesta dissertação efetuou-se um estudo de caso, aplicado ao setor residencial portu-
guês, acerca da viabilidade económica de Unidades de Produção para Autoconsumo com ba-
terias de armazenamento e possibilidade de carregamento de veículos elétricos, tendo sido
adotados três cenários distintos: autoconsumo individual com ligação à rede e veículo elétrico;
autoconsumo individual com ligação à rede, veículo elétrico e uma bateria de armazenamento;
e autoconsumo individual com ligação à rede, veículo elétrico e duas baterias de armazena-
mento.
De acordo com os dados obtidos verificou-se uma significativa redução da importação
energética proveniente da rede elétrica, bem como a viabilidade económica das soluções pro-
postas, que contribuem positivamente para a utilização sustentável dos recursos.
The climate changes that are currently affecting the planet are largely due to the growing of the global energy consumption in the last 50 years, motivated by demographic growth, technological evolution and, above all, the increase in energy consumption from non-re- newable sources. In this way, the energy transition with a view to the sustainable use and de- velopment of resources, such as the integration of renewable energies in the residential and industrial sectors and the adoption of electric mobility, is assumed as a major pillar in order to achieve the goals defined by the European Union and Portugal. Photovoltaic solar technology, namely through Production Units for Self-Consumption, combined with the development of electric mobility appears as a possible way to combat cli- mate change. In this dissertation, a case study was carried out, applied to the residencial portuguese sector, about the economic feasibility of Production Units for Self-Consumption with storage batteries and the possibility of charging electric vehicles, with three different scenarios being adopted: individual self-consumption with connection to the grid and electric vehicle; indivi- dual self-consumption with connection to the grid, electric vehicle and a storage battery; and individual self-consumption with connection to the grid, electric vehicle and two storage bat- teries. According to the results obtained, there were significant reductions in energy imports from the electricity grid as well as the economic feasibility of the proposed solutions, which contribute to the sustainable use of resources.
