The evaluations of the energy storage density, system efficiency and power output, under the effects of insufficient charging/discharging, are presented in Fig. 8, Fig. 10, Fig. 12. The results demonstrate that the actual performance of density and power, except for the system efficiency, could highly deviate from the targets at design conditions.
Remarkable reductions in density and power should be considered seriously. If not well treated, it would bring some uncertainty and insecurity to larger-scale electricity grids. More importantly, this could fundamentally deteriorate the economic performance of an energy storage system over a long period.
Sufficient charging/discharging only occurs on the second day, and the insufficiency extent on the first day and the third day could be about 75 and 50%, respectively. Here, the insufficiency extent of charging/discharging is evaluated by the normalized pressure at the high-pressure tank. Fig. 1.
However, the effects of insufficient charging and discharging, due to the variability of renewable energy have not been investigated before. The output power and the energy density evaluated in the present work could be incorporated with future work of techno-economic analysis.
It can be used to store not only the excessive electricity in normal electricity grids but also the electricity generated from renewable energy like other compressed fluid energy storage systems [, , , , ]. Energy storage systems are normally described as “Peak Shaving and Valley Filling”.
The RTE directly affects the overall performance of Battery Energy Storage Systems (BESS) in several ways: The higher the RTE, the less energy is lost during the storage process. This means that more of the input energy is available for use, resulting in a more efficient system overall.
