针对水库洪水优化调度的非线性、多目标特性,研究了一种水库洪水多目标调度的线性综合优化算法。理论推导与算例仿真表明,该算法通过有限次的单目标优化计算,可直接获得多目标函数最优解集的前端,从而避免了复杂的多目标进化算法的搜索过程,且其最优解集的目标空间分布曲线清晰,直观地表达了当前洪水状况下优化调度解的分布及各目标间的关系,对水库洪水多目标优化调度的决策具有重要意义。
In view of the nonlinear and multi-objective characteristics of reservoir flood scheduling, a linear integrated optimization algorithm for reservoir flood multi-target scheduling is studied. The theoretical derivation and simulation results show that this algorithm can obtain the front-end of the optimal solution set of multi-objective function directly by limited single-objective optimization, which avoids the search process of complex multi-objective evolutionary algorithm and its optimal solution The set of objective spatial distribution curves clearly and intuitively expresses the distribution of optimal scheduling solutions under current flood conditions and the relationship among the targets, which is of great significance to the decision-making of multi-objective optimal scheduling of reservoir floods.
