Multi-objective"Artificial Flood Peak"Scheduling Model Based on NSGA-ⅡAlgorithm
The optimal operation of large hydraulic engineering projects must consider the conflicting objectives of flood control,power generation,shipping,water supply,and ecological protection at the same time,which is a large-scale,non-convex,non-linear,strongly coupled and complex multi-objective optimization problem with constraints.In this study,the scheduling rules of ecological dispatch were incorporated into the model constraints specifically for the ecological dispatch type of"artificial flood peak".And it established multi-objective dispatch model that takes into account the hydropower generation during the execution period of the ecological dispatch plan and the reserved flood control reservoir capacity.The NSGA-Ⅱ algorithm was used to solve the model for the case study of a control reservoir in the Yangtze River basin.The results show that the ecological dispatch process optimized by the model,under the premise of maximizing hydropower generation and reserved flood control reservoir capacity,has a better execution sit-uation of the ecological dispatch plan,and the model can provide support for the decision-making of reservoir ecological dispatch.
