摘　　要：为解决大规模水-光互补系统在非汛期的多时间尺度耦合调度难题,阐明了库水位动态控制调度模式下的水-光中短期互补的基本原理,分别构建了考虑非汛期库水位动态控制的水-光互补中期和短期多目标优化调度数学模型,并以青海省黄河上游班多水-光互补系统为例验证模型有效性。结果表明,与传统调度模式相比,库水位动态控制调度模式下水库非汛期日初库水位平均增高0.94~1.17 m,水电日均发电水头平均提高0.06%~0.80%;非汛期水-光互补系统发电量提高0.221%,弃光电量降低0.025%。因此,非汛期库水位动态控制调度可提高水-光中短期互补性能。To solve the multi-time scale coupling scheduling problem of the large-scale hydro-photovoltaic complementary system in non-flood season,the basic principle of short-term hydro-photovoltaic complementary under the dynamic control scheduling mode of reservoir water level was expounded.The mathematical models of medium-term and short-term multi-objective optimal scheduling of hydro-photovoltaic complementary considering the dynamic control of reservoir water level in non-flood season were established respectivel.The effectiveness of the models was verified by taking Banduo hydro-photovoltaic complementary system in the upper reaches of the Yellow River in Qinghai Province as an example.The results show that compared with the traditional dispatching mode,the daily initial reservoir water level in non-flood season increases by 0.94-1.17 m on average,and the average daily hydropower generation head increases by 0.06%-0.80%under the reservoir water level dynamic control dispatching mode.In non-flood season,the power generation of hydro-photovoltaic complementary system increases by 0.221%,and the amount of photovoltaic power curtailments decreases by 0.025%.Therefore,the dynamic control of reservoir water level in non-flood season can improve the medium-and short-term hydro-photovoltaic complementary performance.
