摘要：This paper constructs a multi-objective flood forecasting optimization operation model based on inflow forecasting information considering flood control, power generation, and navigation. The optimization-simulation-test algorithm and modified differential evolution for multi-objective optimization (DEMO) were used. Some non-dominated solutions were derived from optimization of the inflow data of 126 years (1882-2007) and test by 1000-year design floods. The solutions were distributed uniformly and the algorithm was efficient. The flood during August 2009 was also used to test the selected solution. The results show that the optimal schemes can generate extra hydropower energy, and save great flood water resources. The navigation days for all types of ships are also increased greatly. To maximize comprehensive utilization benefits on the premise of flood control safety, the traditional design flood routing method is well combined with the optimization method by reservoir operation chart for flood control based on inflow forecasting, which provides a new way for reservoir flood control operation by considering the comprehensive utilization benefits.
