O armazenamento de energia é um componente essencial dos sistemas de energias renováveis e das micro-redes. O principal objetivo é investigar qual é o tipo mais adequado de armazenamento de curto prazo a incluir no MGS: baterias ou super-capacitores. Para avaliar o armazenamento de energia eléctrica em baterias e compará-lo com a tecnologia avançada de super-capacitores, foi concebida e construÃda uma instalação experimental. Foi realizado um conjunto de experiências para investigar as diferentes caraterÃsticas e a sua adequação à s condições de carga e descarga. Os resultados mostraram que o supercondensador tem uma densidade de potência superior à da bateria, enquanto a bateria ultrapassa o supercondensador em termos de densidade de energia. Assim, os resultados confirmam o entendimento de que o supercondensador é mais adequado para processos de carga e descarga rápidos do que a bateria, que é mais adequada para tempos de carga e descarga longos. Além disso, do ponto de vista económico, a bateria continua a ser mais económica do que os supercondensadores. Os resultados são expressos principalmente em termos de eficiência energética especÃfica e de eficiência de carga/descarga; mostram que as pilhas são muito úteis para aplicações de elevada densidade energética.
