Compressed air energy storage (CAES) systems offer significant potential as large-scale physical energy storage technologies. Given the increasing global emphasis on carbon reduction strategies and the rapid growth of renewable energy sources, CAES has garnered considerable attention.
During periods of low power demand, the system utilizes a low-pressure air storage chamber for air storage and release. Conversely, when higher power output is required, the high-pressure air storage chamber is engaged for air storage and release. The authors investigated the impact of this system enhancement on the integration of wind power.
For instance, the varying pressure of the air storage chamber poses challenges in determining the optimal back pressure for the compressor and the inlet pressure for the expander. Moreover, the fluctuating system power introduces multiple possibilities for the design scheme regarding pressure and flow rate.
The findings indicate that, in comparison to the corresponding constant pressure ratio CAES system, the variable pressure ratio CAES system exhibits a 12% reduction in compressor power consumption, a 17.9% increase in turbine output work, and a 13.1% improvement in the round-trip efficiency of the system.
