In a multi-energy scenario, the SPT station can be a peak shaving plant when it is equipped with thermal energy storage. Its character confines the peak regulation capacity of the coal power plant. However, the ramp rate of SPT station could reach 20% per minute, much higher than that of 2%–5% per minute of a coal power plant.

When the Energy Storage System (ESS) participates in the secondary frequency regulation, the traditional control strategy generally adopts the simplified first-order inertia model

They also indicated the power supplied to each BESS during the peak shaving service is well below the rated power of the storage systems themselves. Unlike peak shaving, the power balancing service is an on-demand service, which the grid operator can request from 13:00 onwards.

To address the issue of peak shaving of power grid, the energy storage systems have drawn many scholars'' attentions [23], such as compressed air energy storage (CAES) system and liquid air energy

Battery energy storage system (BESS) has the potential to solve this issue by storing the energy in BESS during the off-peak intervals and discharging during the peak intervals (to charge EVs). In this case, not only the impact on the grid is minimized but also the inconvenience caused by the shifting of load during peak hours can also be mitigated

1. Introduction. With a low-carbon background, a significant increase in the proportion of renewable energy (RE) increases the uncertainty of power systems [1, 2], and the gradual retirement of thermal power units exacerbates the lack of flexible resources [3], leading to a sharp increase in the pressure on the system peak and frequency regulation
