摘要：
The Jinsha River basin is selected as a study area to validate the rationality and reliability of the methodology on synergetic control of reservoir flood operating water levels of cascade reservoirs proposed in the last paper. Firstly, the dynamic multi-objective algorithm was employed to optimize the operation model by considering dynamic forecast horizons. Secondly, risk - benefit indicators were employed to evaluate the schemes of synergetic control of flood operating water levels. Lastly, the Wudongde, Baihetan, Xiluodu and Xiangjiaba cascade reser¬voirs constituted the study case and the synergetic relationship of flood operating water levels of the cascade reser¬voirs was analyzed. The results show that: ( 1) as compared to the static control scheme of flood limited water lev¬els , the synergetic control scheme of flood operating water levels of cascade reservoirs can raise the values of reser¬voir water levels without increasing flood risk; (2) the average annual power generation and the maxium reduction value of average annual spilled water volume in the flood season can reach 107.1 billion kW- h with the im¬provement rate of 11.1% and 64.9 billion m with the improvement rate of 14.3%, respectively; and (3) the syn¬ergetic control scheme can effectively boost the use efficiency of flood resources and comprehensive benefits. © 2023 China Water Power Press.
