Abstract(s)
A necessidade de redução de emissão de gases de efeito de estufa na atmosfera, requer
recursos sustentáveis, pelo que a aposta em veículos elétricos tende a ser uma ótima
solução para o meio ambiente. Contudo, a utilização em massa deste tipo de veículos
poderá causar grandes impactos nas redes elétricas. Neste contexto, a presente
dissertação apresenta um estudo e análise do comportamento de uma rede de baixa
tensão com veículos elétricos integrados. Começa por apresentar-se uma perspetiva
geral de quais são as causas e efeitos quando se conetam veículos elétricos à rede
elétrica, tendo em consideração os níveis de carregamento, modos de carregamento e
normas. Através deste estudo, será possível verificar que o impacto na rede por esta
adoção maciça coloca em causa as atuais infraestruturas, e mesmo as futuras. Assim,
apresenta-se uma estratégia baseada em soluções de armazenamento de energia, de
modo a minimizar este impacto. Os diversos estudos serão suportados por simulações
realizadas pelo programa matlab.
The need to reduce the emission of greenhouse gases into the atmosphere requires sustainable resources, so the bet on electric vehicles tends to be a great solution for the environment. However, the mass use of these types of vehicles can have major impacts on the electrical networks. In this context, the following dissertation presents a study and analysis of the behavior of a low-voltage network with integrated electric vehicles. It begins by presenting an overview of what are the causes and effects when connecting electric vehicles to the electrical network, taking into account the charging levels, charging modes and standards. Through this study, it will be possible to verify that the impact on the network by this massive adoption calls into question the current infrastructures, and even future ones. Thus, in order to minimize this impact, a strategy based on energy storage solutions is presented. The various studies will be supported by simulations carried out by the matlab program.
