Optimization method and device for dam inflow correction

Abstract

The present invention provides a method and apparatus for optimizing dam inflow correction. The method for optimizing dam inflow correction includes the steps of obtaining initial dam inflow values ​​for multiple time periods, inputting the initial dam inflow values ​​for each time period into a pre-established multi-objective optimization model, and solving the multi-objective optimization model to obtain a non-dominated solution set, wherein the optimization variables of the multi-objective optimization model include weights and weight distribution coefficients for each time period, and any non-dominated solution in the non-dominated solution set includes a weight value and weight distribution coefficient value for each time period and a dam inflow correction value for each time period, and the dam inflow correction value is calculated based on the initial values, weights, weight distribution coefficients, and initial values ​​for adjacent time periods, and selecting an optimized dam inflow correction value for each time period based on the non-dominated solution set of dam inflow correction values. According to the present invention, by introducing variable weights and distribution coefficients when correcting dam inflow, the correction process can be prevented from being too smooth, which would affect the flood peak correction results.
