摘　　要：为充分利用水电站水库汛期在预报无洪水或小洪水时的调节能力,将汛期运行水位动态控制域对应库容作为调节风光运行的可用库容,在提高水库调节能力的基础上给出了考虑入库洪水实时状态的汛期水电站水库动态消纳风光调度模式,以风光出力期望值加水电出力之和与负荷偏差最小为目标,结合风光出力不确定性建立了汛期水风光多能互补动态调度模型,并以福建省水口水电站为例进行模拟调度计算。结果表明:所提动态消纳风光调度模式能够在保证防洪安全的前提下充分合理利用水位动态控制域内的调节能力来调节风光出力,使失负荷时段数和发电量缺口期望值相较于传统调度模式分别降低约37%和32%,水电站水库平均发电水头提高约4.39%,不仅可提高系统出力可靠性,且能增加系统运行效益。研究成果可为汛期调节风光出力提供参考。To fully utilize the regulation capacity of hydropower reservoirs during flood seasons when no flood or only minor floods are forecasted,the reservoir's storage capacity within the dynamic control range of the flood season operation water level is considered as the available capacity for regulating wind and solar power generation.On the premise of enhancing the reservoir's regulation capability,a dynamic scheduling mode for the absorption of wind and solar power was proposed,considering the real-time state of incoming floods.The model aimed to minimize the deviation between the sum of expected wind,solar power,and hydropower output,and the load demand.The model was established considering the uncertainties in wind and solar power output.A case study was conducted with the Shuikou Hydropower Station in Fujian Province.The results showed that the proposed dynamic operation model for wind and solar power absorption can fully and rationally utilize the regulation capacity within the dynamic control range of the water level,ensuring flood safety.Compared to the traditional operation model,the proposed model reduced the number of periods with load deficits and the expected value of generation shortfalls by approximately 37%and 32%,respectively,while increasing the average hydropower generation head by about 4.39%.This not only improved system output reliability but also enhanced system operational benefit.The research findings can provide a reference for regulating wind and solar power output during the flood season.
