At present, the utilization of the pumped storage is the main scheme to solve the problem of nuclear power stability, such as peak shaving, frequency regulation and active power control [7].[8] has proved that the joint operation of nuclear power station and pumped storage power station can peak shave more flexibly and economically.
1. Introduction Due to their advantages of fast response, precise power control, and bidirectional regulation, energy storage systems play an important role in power system frequency regulation (Liu et al., 2019), voltage regulation (Shao et al., 2023, Zhou and Ma, 2022), peak shaving (Li et al., 2019, Dunn et al., 2011, Meng et al., 2023a),
Grid battery storage systems are crucial for grid stability and reliability. They help balance supply and demand, handle renewable energy fluctuations, and offer backup power during peak demand or failures. Operators depend on them to respond swiftly to power demand changes, making efficient storage a vital aspect of grid resilience.
The results show that the energy efficiency of low power charge-discharge is generally better than that of high power charge-discharge, while the percentage of auxiliary energy
