Abstract(s)
O panorama energético atual caracteriza-se por um aumento do consumo da energia elétrica e pela preferência por tecnologias renováveis e limpas. Por vezes existe capacidade de produção de energia por parte deste tipo de fontes que não é absorvida pelo sistema de energia.
Os Sistemas de Armazenamento de Energia (SAE) podem ser utilizados para apoiar em casos de desequilíbrio entre a produção e o consumo, pois permitem armazenar o excedente de produção de energia elétrica de forma a que mais tarde seja consumida, sem que haja necessidade de recorrer à geração fóssil. Num cenário oposto, o SAE pode auxiliar os equipamentos de geração na resposta a défices de produção face às necessidades energéticas, comportando-se como uma fonte de energia elétrica. Neste trabalho foi analisado um SAE constituído por baterias (Battery Energy Storage System, BESS).
O objetivo principal deste trabalho é implementar um esquema de proteção que garanta a correta operação do SAE. É fundamental que os dispositivos de proteção atuem de forma fiável e segura, por forma a detetar os defeitos na sua fase mais precoce e assim evitar a propagação de avarias, minimizando os danos no equipamento e reduzindo o período e custos de indisponibilidade
The current energy landscape is characterized by an increase in electricity consumption and a preference for renewable and clean technologies. Sometimes there is production capability from this kind of sources that is not absorbed by the energy system. Energy Storage Systems (ESS) can be used to support in cases of imbalance between production and consumption, as they allow the storage of surplus electricity production so it can be consumed later, without the need to resort to fossil generation. In an opposite scenario, the ESS can assist the generation equipment response to production shortfalls by behaving as an electrical energy source. In this work was analyzed a ESS comprised by batteries. This work main goal is to implement a protection scheme that guarantees ESS correct operation. It is essential that the protection devices act with reliability and safety, in order to detect the faults at their earliest stage and, thus, prevent malfunctions, minimizing equipment damage and reducing outage’s time and costs.
