Abstract: To fully utilize the regulation capacity of hydropower reservoirs during flood seasons when no flood or only minor floods are forecasted ,the reservoir 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 hy- dropower 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 con- trol 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.
