As is well known, the anti-peaking characteristic of wind generation leads to evident curtailments of wind farms. With high energy density and flexible installation position, the battery energy storage system (BESS) can provide a new routine to relax the bottleneck of the peak-load regulation, conducive to the absorption of wind power and the economy
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

Electrochemical and other energy storage technologies have grown rapidly in China. Global wind and solar power are projected to account for 72% of renewable energy generation by 2050, nearly doubling their 2020 share. However, renewable energy sources, such as wind and solar, are liable to intermittency and instability.
The rapid growth of renewable energy generation has created a large market demand for energy storage facilities. By the end of the first quarter of 2024, the
