摘　　要：为实现梯级水风光蓄联合发电系统高效多能互补,研究考虑梯级水电融合抽蓄改造的风光发电多目标容量优化配置方法。以联合发电系统外送通道利用率最大和受端电网剩余负荷峰谷差最小为目标,优化联合发电系统风电和光伏发电的配置容量;考虑风电和光伏发电季节性波动,基于K-means聚类构建风电和光伏发电出力的典型场景,提出了梯级水风光蓄全场景互补运行模型,并发展了便于快速求解的混合整数线性化模型。以小金川梯级小水电周边的风电场与光伏电站为例,对所提方法的有效性进行了验证,分析了梯级水风光蓄联合系统的互补性,对比说明了混合式抽蓄在联合发电系统中的作用。In order to achieve efficient multi-energy complementarity in the cascaded hydro-wind-photovoltaic-pumped storage co-generation system,a multi-objective capacity configuration optimization method for wind and photovoltaic power generation is studied considering retrofitting cascade hydropower with pumped storage.With objectives of maximizing the utilization rate of external transmission channel and minimizing the peak valley difference of residual load in the receiving end grid,the capacity of wind and photovoltaic power generation is optimized.Considering the seasonal fluctuation of wind and photovoltaic power generation,typical scenarios of wind and photovoltaic power generation outputs are constructed based on K-means clustering.Based on this,a full-scenario complementary operation model for cascaded hydro-wind-photovoltaic-pumped storage co-generation system is proposed,and a mixed-integer linearization model is developed for quick solution.The effectiveness of the proposed method is verified using the wind and photovoltaic power stations around small cascade hydropower stations in Xiaojinchuan River as an example.The complementarity of hydro-wind-photovoltaic-pumped storage co-generation system is analyzed,and the role of pumped storage in the combined power generation system is compared and explained.
