多目标梯级水库优化调度问题的免疫遗传算法

Immune genetic algorithm in solving multi-objective optimal cascade reservoir dispatching

在研究现有多目标遗传算法的优越性与存在不足的基础上,受生物免疫原理的启发,提出了一种新的优化调度算法—多目标免疫遗传算法,有效克服遗传算法的早熟、群体多样性不足及搜索速度慢等问题。同时.以梯级水库优化调度发电量和保证出力为目标,建立了三峡梯级水库多目标优化调度模型。通过实例研究计算,论证了该方法的有效性和实用性。

Based on study of the existing multi-objective genetic algorithms' property and enlightened by the immune principle of crea- ture,a novel algorithm-MOIGA is proposed.Considering electric power output and firm power objectives,the multi-objective optimization model is established for the Three Gorge cascade reservoir dispatching to demonstrate the validity and practicability of this method.
