摘　　要：基于常规水电水库,新建抽水蓄能电站可增加系统调峰能力和缓解新能源消纳压力,亦会影响常规水电运行过程。针对短期时间尺度下抽水蓄能电站对常规水电水库日内水位波动的影响,构建了抽水蓄能与常规水电短期联合运行优化模型,分析了抽水蓄能典型运行模式下常规水电水库水位的变化过程,以黄河上游梯级水库和贵南哇让抽水蓄能电站为例进行了研究。结果表明:该模型考虑了抽水蓄能与常规水电之间的水力联系和电力联系,适应但不限于“一抽一发”、“一抽两发”运行模式;相较于无抽水蓄能电站,抽水蓄能电站运行后会改变原始梯级水库水位变幅(增加约1.07~1.33 m);发电和抽水时段是影响下库水位变幅的主要因素。研究成果可为抽水蓄能与常规水电联合消纳新能源所产生的影响提供技术参考。Based on conventional hydropower reservoirs,the construction of pumped storage power stations can increase the system’s peak regulating capacity and relieve the absorption pressure of new energy,and it also can affect the operation process of conventional hydropower.In view of the influence of the pumped storage power station on the intra-day water level fluctuation of conventional hydropower reservoirs in a short time scale,a short-term joint operation optimization model for pumped storage and conventional hydropower is constructed,with the variation process of water level of conventional hydropower reservoirs in a typical operation mode of pumped storage analyzed.Examples of cascade reservoirs in the upper reaches of the Yellow River and Waerang pumped storage power station in Guinan are studied.The results show that using the model takes into account the hydraulic connection and electric connection between pumped storage and conventional hydropower,and adapts to but is not limited to the operation mode of"one-pump-one-generate"scheme,or"one-pump-two-generate"scheme.Compared with the non-pumped storage power station,the pumped storage power station will change the amplitude of the original cascade reservoir water level after operation(increased by about 1.07~1.33m).Generation time and pumping time are the main factors affecting the variation of lower reservoir water level.The research results can provide a technical reference for the influence of combined consumption of new energy by pumped storage and conventional hydropower.
