For each typical application scenario, evaluation indicators reflecting energy storage characteristics will be proposed to form an evaluation system that can comprehensively evaluate the operation effects of various functions of energy storage power stations in the actual operation of the power grid.
Evaluating the actual operation of energy storage power stations, analyzing their advantages and disadvantages during actual operation and proposing targeted improvement measures for the shortcomings play an important role in improving the actual operation effect of energy storage (Zheng et al., 2014, Chao et al., 2024, Guanyang et al., 2023).
Calculation results of relative closeness. According to the evaluation values of the operational effectiveness of various energy storage power stations, station F has the highest evaluation value and station C has the lowest evaluation value.

Decarbonization of the electric power sector is essential for sustainable development. Low-carbon generation technologies, such as solar and wind energy, can replace the CO2-emitting energy so.
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
The number of sites available for compressed air energy storage is higher compared to those of pumped hydro [, ]. Porous rocks and cavern reservoirs are also ideal storage sites for CAES. Gas storage locations are capable of being used as sites for storage of compressed air .
Modularity of compressed air energy storage systems is another key issue that needs further investigation in other to make them ideal for various applications.

Expansion machines are designed for various compressed air energy storage systems and operations. An efficient compressed air storage system will only be materialised when the appropriate expanders and compressors are chosen. The performance of compressed air energy storage systems is centred round the efficiency of the compressors and expanders.
The reverse operation of both components to each other determines their design when integrated on a compressed air energy storage system. The screw and scroll are two examples of expanders, classified under reciprocating and rotary types.
There are several compression and expansion stages: from the charging, to the discharging phases of the storage system. Research has shown that isentropic efficiency for compressors as well as expanders are key determinants of the overall characteristics and efficiency of compressed air energy storage systems .
The battery energy storage system (BESS), with 200MW capacity, will hold 800 megawatt hours (MWh) of power, enough to back 96,000 households. The development tracks the project's construction permit given in July 2023 and its selection for capacity remuneration in October 2023.
