SUMMARY:

Global demand for electricity has increased rapidly in recent decades, which is resulting in the decline of non-renewable energy resources such as coal, natural gas and oil. This space is largely occupied by renewable energy sources, and among them, wind and solar photovoltaic generation have been the most prominent. In Brazil, renewable energy is a success case, historically dominated by hydroelectric generation. However, the expansion of this generation source faces progressively higher costs and constraints. In this scenario, generation from wind and solar photovoltaic sources has shown a considerable increase in the last 10 years. But, the intermittent characteristics of these sources can generate instability in power grids. Therefore, technologies with the capacity to absorb sudden power variations are needed. As well as ensuring an adequate power reserve, such as compressed air energy storage systems (CAES). The round-trip efficiencies, 1 and 2, of the reference CAES system were 0.31 and 0.23 respectively, and the exergetic efficiency was 0.23. This configuration was compared with two more advanced configurations, integrated with thermal energy storage (TES) systems by sensible heat, both in fixed bed and in thermal oils. Thermo-economic analyses were performed to evaluate strategies for trading the stored electrical energy in each configuration. Based on the expanded failure modes and effects analysis (FMEAe) method, the reliability of these systems was assessed to select the most important components for the reliability of the installation. In each analysis, the effect of the primary energy source used to drive the CAES system was evaluated. Finally, an integrated diagnostic methodology was structured based on the analysis methods and prioritization criteria.
