Joint operation strategy of water impoundment period of Three Gorges-Jinsha River lower reach cascade reservoirs
Aiming at the competitively impounding contradiction of Three Gorges-Jinsha River lower reach cascade reservoirs in flood recession period,taking Xiluodu,Xiangjiaba,Three Gorges,Gezhouba cascade reservoir group system as research object,scenario sets were established with different hydrological year types,beginning impounding times and beginning water levels;taking maximum expected generated energy as target,multi objective stochastic optimal joint operation model was built for water impounding period,and optimal scheme of each impoundment scenario was generated;considering the flood risk and the benefit,on the basis of fill storage rate,cascade expected surplus water and cascade expected power output,Xiluodu reservoir and Xiangjiaba reservoir were recommended to begin impounding on September 11,Three Gorges reservoir on September 10 in high flow years,Xiluodu reservoir and Xiangjiaba reservoir were recommended to begin impounding on September 11,Three Gorges reservoir on September 1 in mean flow years,Xiluodu reservoir and Xiangjiaba reservoir were recommended to begin impounding on September 1,Three Gorges reservoir on August 21 in low flow years.
