Abstract
As the largescale cascaded reservoirs have been developed rapidly in recent years river basin flood control RBFC has become a complex multiobjective and multireservoir problem In order to realize the optimal operation and management of reservoirs in mainstreams and branches this paper presents a generalized multiobjective flood control model MOFCM for joint optimal dispatching of cascade reservoirs which is applied to cascade reservoirs in lower reaches of Jinsha River and Three Gorges Reservoir in Yangtze River JFCR–TGR Meanwhile a multiobjective cultural selfadaptive electromagnetismlike mechanism MOSEM algorithm is introduced to solve RBFC problem In the case study comparing with the natural runoff of the Chuan River the maximum release of optimal schemes is lesser its reduced range is from 1727 to 12887 m3/s and the flood peak deduction rate is from 64 to 48 Results of case studies demonstrate that MOFCM is practicable and efficient for multipurpose multireservoir flood control The optimal operation schemes obtained by MOSEM in JFCR–TGR system can be used to assist the decision makers in choosing the most efficient scheme Furthermore MOFCM can accomplish multipleobject optimization effectively under various scheduling situations
