在高比例新能源并网背景下，水电机组独立调峰容易出现启停频繁和低负荷振动等风险，威胁安全稳定运行。为缓解这一问题，引入电化学储能系统，与水电协同承担调峰任务。电化学储能的参与不仅提升了系统总发电量，减少了弃电与缺电，还显著降低了水电机组的启停次数和振动区运行时间，改善了运行风险。研究表明，电化学储能能够在多能互补基地中发挥关键的柔性调节作用，对提升新能源利用水平和保障水电机组安全运行具有重要意义，亦为类似区域高比例新能源系统的储能配置与调度优化提供了参考。
Abstract：Under the background of a high proportion of new energy being connected to the grid, hydropower units that undertake peak regulation independently are prone to frequent start-stop operations and low-load vibration risks, threatening safe and stable operation. To address this issue, this paper introduces an electrochemical energy storage(EES) system to coordinate with hydropower in peak regulation. The participation of EES not only increases the total power generation and reduces curtailment and shortages, but also significantly decreases the start-stop frequency and the duration of vibration-zone operation of hydropower units, thereby mitigating operational risks. The results demonstrate that the EES plays a key role in providing flexible regulation in multi-energy complementary bases, enhancing new energy utilization and ensuring the safe operation of hydropower units. This study provides a reference for energy storage configuration and dispatch optimization in regions with high renewable penetration.
