The low predictability of hourly available power of wind turbines and their volatile output, cause multiple hardships in the power system which are supposed to be handled by means of keeping a higher amount of contingency and regulation reserve. The intensified reserve requirement along with operational constraints may enforce wind-farms to operate below their maximum available power. It's shown that Pumped-Storage systems, not merely as storage capacity, but also as a high-quality reserve providers make the power system capable to lessen wind power curtailment. It is investigated how increasing the reserve requirement may restrict the overall renewable production and how Pumped-Storage can relieve this restriction. The Pumped-Storage system is precisely modeled based on Siahbisheh, a 1000 MW Pumped-Storage system in northern part of Iran. The soundness of the obtained results is fortified by using actual technical data based on Manjil wind-farm, and other active generating units in Iranian power system, as well as actual prices from the historical records of Iran Wholesale Electricity Market. As well as IEEE 24-Bus test system, the performance of Pumped-Storage system is analyzed on the actual network of Gilan Province in Iran.

风力涡轮机每小时可用功率的低可预测性及其波动性输出会导致电力系统出现多重困难，应该通过保持较高的应急费用和法规储备来应对这些困难。增加的储备要求以及操作限制可能会迫使风电场在其最大可用功率以下运行。结果表明，抽水蓄能系统不仅可以作为存储容量，而且可以作为高质量的后备供应商，使电力系统能够减少风力发电的削减。研究了增加储备需求如何可能限制整个可再生能源的生产以及抽水蓄能如何缓解这一限制。抽水蓄能系统是基于Siahbisheh精确建模的，Siahbisheh是伊朗北部的1000 MW抽水蓄能系统。通过使用基于Manjil风电场和伊朗电力系统中其他有功发电机组的实际技术数据，以及伊朗批发电力市场历史记录中的实际价格，可以增强所得结果的可靠性。以及IEEE 24-Bus测试系统，在伊朗Gilan Province的实际网络上分析了Pumped-Storage系统的性能。
