本文考虑了不确定的风预测的价值存储的能量（如抽水蓄能）在未来的英国的影响。风力发电系统提供了超过20%的能源。从现有储备来源提供更多增加的储备需求可以提高系统运行效率，增强风电吸收，节省燃料成本并减少二氧化碳排放。一般来说，基于存储的常设备用的价值是由安装的风力和发电系统的灵活性。在发电灵活性低和风力装机容量大的系统中，效益更为显著。储能是唯一能够在高风力/低需求期间储存产生的多余能量，并随后根据需要释放这些能量。当存储与传统发电提供的常备储备相结合时（例如，开式循环燃气轮机），它是有价值的，在服务的高度频繁的较小的不平衡
This paper considers the impact of uncertain wind forecasts on the value of stored energy (such as pumped hydro) in a future U.K. system, where wind supplies over 20% of the energy. Providing more of the increased requirement for reserves from standing reserve sources could increase system operation efficiency, enhance wind power absorption, achieve fuel cost savings, and reduce CO2 emissions. Generally, storage-based standing reserve's value is driven by the amount of installed wind and by generation system flexibility. Benefits are more significant in systems with low generation flexibility and with large installed wind capacity. Storage is uniquely able to stock up generated excesses during high-wind/low-demand periods, and subsequently discharge this energy as needed. When storage is combined with standing reserve provided from conventional generation (e.g., open-cycle gas turbines), it is valuable in servicing the highly frequent smaller imbalances
