Este trabalho de dissertação pretende destacar a importância hoje, e no futuro, da integração de sistemas de baterias nos SEE para armazenamento de energia, referindo-se às principais vantagens da sua aplicação, nomeadamente como apoio à Mobilidade Elétrica. Os sistemas de armazenamento de energia (ESS), além de darem um passo rumo à autonomia energética, ao permitirem guardar eletricidade para momentos em que não está a ser produzida, têm também a vantagem de amenizar as variações de preços e de potência que estão dependentes das condições meteorológicas (sol, vento, ou água nas barragens). Nas fontes de energia renováveis, especialmente na fotovoltaica, pela sua característica de produção intermitente, o armazenamento de energia será fulcral para que o consumo da energia de origem fotovoltaica descole da franja residual em que se encontra atualmente (entre 1% e 2,5% na atualidade). A mobilidade elétrica é também hoje um setor de inegável crescimento e, com ele, novas exigências sobre a atual infraestrutura de distribuição elétrica, obrigarão ao reforço e ao investimento dessa infraestrutura para garantir o seu correto funcionamento. Com a implementação de soluções de armazenamento de energia, em apoio a postos de carregamento de veículos elétricos, o crescimento da mobilidade elétrica é possível sem necessidade de reforço da infraestrutura e, se associado a sistemas de produção solar fotovoltaica, pode, inclusive, reduzir as exigências sobre a rede.
This paper aims to highlight the importance of, today and in the future, the integration of battery systems in the electrical grid for energy storage, referring to the main advantages of its application, namely as support for Electric Mobility. Energy storage systems, in addition to taking a step towards energy autonomy by storing electricity for times when it is not being produced, also have the advantage of mitigating price and power variations that are dependent on weather conditions (sun, wind, or water in the dams). In renewable energy sources, especially in photovoltaics, due to their intermittent production characteristics, energy storage will be crucial for the consumption of photovoltaic energy to take off from the current residual fringe (between 1% and 2.5% in present). Electric mobility is also today an undeniable growth sector and, with it, new demands on the current electrical distribution infrastructure, will force the reinforcement and investment of this infrastructure to ensure its correct functioning. By implementing energy storage solutions in support of electric vehicle charging stations, the growth of electric mobility is possible without the need for infrastructure reinforcement and, if combined with photovoltaic solar production systems, can even reduce network requirements.
