Multi-objective Optimization of Large-scale Multi-reservoir Flood Control Operation

Joint operation of reservoir group is an important method for flood mitigation. Most of the existing flood control operation methods only focus on a single reservoir and a single object, which cannot take into account the coordination and complementarity of different reservoirs, and it is difficult to comprehensively consider the safety of multiple flood control objectives in the upstream and downstream of the basin. In this context, this paper proposed a multi-objective modeling and optimization method for flood control operation of large-scale reservoir groups based on different pre-set frameworks. 12 large reservoirs in the Yangtze River Basin were selected as a case. The results show that the proposed method can reasonably and effectively deal with the complex optimization problem of large-scale reservoir group operation scheme, and can further improve the intelligent level of multi-reservoir joint flood control operation.
