储能系统是保证现代电力系统能源供应连续性和可靠性的重要组成部分。由于天气条件的波动以及负荷需求行为的不确定性，可再生能源发电机组的间歇性和不确定性使可再生能源发电机组成为电力系统灵活性管理的重要组成部分。通常，负荷需求曲线可以分为高峰和非高峰时期，而可再生能源发电的增加使负荷生成动态变得更加复杂。因此，热发电（TG）机组需要更频繁地开启和关闭，以满足系统负荷需求。鉴于此，一些研究工作已经针对分析ess在解决最优单元承诺（UC）问题，最小化运营成本和最大化利润方面的好处，同时确保供应可靠性。本文回顾和总结了近年来针对上述电力系统运行问题的一些研究工作和相关统一通信模型，为未来电力系统灵活性管理的有效解决方案提供了清晰的概念和提示。最后，模拟了一个示例问题，以便可视化地显示具有ESSs的UC问题的公式及其解。
Energy storage systems (ESSs) are essential to ensure continuity of energy supply and maintain the reliability of modern power systems. Intermittency and uncertainty of renewable generations due to fluctuating weather conditions as well as uncertain behavior of load demand make ESSs an integral part of power system flexibility management. Typically, the load demand profile can be categorized into peak and off-peak periods, and adding power from renewable generations makes the load-generation dynamics more complicated. Therefore, the thermal generation (TG) units need to be turned on and off more frequently to meet the system load demand. In view of this, several research efforts have been directed towards analyzing the benefits of ESSs in solving optimal unit commitment (UC) problems, minimizing operating costs, and maximizing profits while ensuring supply reliability. In this paper, some recent research works and relevant UC models incorporating ESSs towards solving the abovementioned power system operational issues are reviewed and summarized to give prospective researchers a clear concept and tip-off on finding efficient solutions for future power system flexibility management. Conclusively, an example problem is simulated for the visualization of the formulation of UC problems with ESSs and solutions.
