摘　　要：抽水蓄能电站具有优良的调峰填谷能力,能够有效提高电网消纳风电的能力。基于蒙西电网和呼和浩特抽水蓄能电站的实际数据,对抽水蓄能电站与大规模并网风电联合优化运行进行了模拟和研究。考虑风电的间歇性和波动性,建立了抽水蓄能电站与风电联合运行的优化模型。然后分别利用供热期和非供热期的系统数据,对蒙西电网中呼和浩特抽水蓄能电站与风电的联合运行进行了模拟,验证了模型的有效性,并说明了抽水蓄能电站与大规模并网风电联合运行的可行性以及带来的显著效益:供热期存在弃风时,抽水蓄能电站充分发挥调峰填谷的能力以减少弃风;非供热期弃风不明显时,抽水蓄能电站主要为风电提供备用,并平衡风电出力波动。With its excellent peak clipping and valley filling capability,the pumped storage power station can improve the accommodation capability of the wind power.Based on the actual data of West Inner Mongolia power grid and Hohhot pumped storage power station,the optimal joint operation of pumped storage power station and large-scale grid-connected wind power is simulated and investigated.By considering the intermittency and fluctuation of wind power,an optimization model for the joint operation is developed.The validity of the model is verified through simulation of the joint operation of Hohhot pumped storage power station and wind power integrated to West Inner Mongolia power grid based on the actual data of heating season and nonheating season.The simulation also shows the feasibility and benefit of the joint operation.During the heating season when part of the wind power is curtailed,the pumped storage power station shifts peak load and helps the power grid to accommodate more wind power.During the nonheating season with little wind power curtailment,the pumped storage power station is reserved for wind power and balances the fluctuation of wind power.
