Resumen
Dentre as diversas tecnologias de armazenamento de energia elétrica, o armazenamento de energia por ar comprimido (CAES), é um método promissor. Porém, a disponibilidade da fonte primária poderia afetar a confiabilidade dos sistemas CAES. Adicionalmente, as análises de confiabilidade destes sistemas não são muito abundantes na literatura. Portanto, no presente trabalho foi realizada uma análise de confiabilidade sobre um sistema CAES de pequeno porte que armazena energia elétrica de fontes renováveis de natureza intermitente, eólica ou solar fotovoltaica. O método de análise de modos de falhas e efeitos expandida (FMEAe) foi utilizado para avaliar a confiabilidade do sistema. Para aplicação deste método foi usada como referência o esquema de interconexão dos componentes de uma planta real. Os resultados mostraram a contribuição ao risco do sistema de componentes geralmente considerados menos importantes na literatura, como válvulas e interruptores, bem como o efeito da fonte primária de energia na confiabilidade do sistema.
Among the various electrical energy storage technologies, compressed air energy storage (CAES) is a promising method due to its high reliability, scalability, economic viability and low environmental impact. However, the availability of the primary source could affect the reliability of CAES systems. In addition, reliability analyses of this type of system are not very abundant in the literature. Therefore, in this study, a reliability analysis was carried out on a small CAES system which stores electricity from intermittent renewable sources, wind or solar photovoltaic. The expanded Failure Modes and Effects Analysis (FMEAe) method was used to assess the system's reliability. To apply this method, the components interconnection scheme of a real plant was used as a reference. The results showed the contribution to system risk of components generally considered less important in the literature, such as valves and switches, as well as the effect of the primary energy source on system reliability.
