基于决策因子选择的梯级水库多目标优化调度规则研究
Multi-objective cascade reservoir optimal operation rules based on decision factor selection
摘要
Abstract
A cascade-reservoir input-variables selection (CIS) method considering the relations between input variables and decision-making in optimal reservoir operation was proposed using the Extra-Tree model.According to the selection results,the multi-objective reservoir operation rules for the maximization of water supply and power generation were extracted by Gaussian Radial Basis Functions and optimized by Pareto-Archived Dynamically Dimensioned Search (PA-DDS) algorithm.With a case study of Hanjiang cascade reservoirs,it is shown that the CIS method can select stable input variables with less redundant information for the reservoir decision-making,and the input variables selected by CIS not only help to obtain better distributed non-dominated solutions in multi-objective optimization,but also can control the use of available water in different seasons effectively.The annual mean power generation and water supply increase 0.33％ and 7.84％ in the operation mainly for power generation.关键词
