中文摘要：

为了提高遗传算法在多目标梯级水库优化调度中的应用效果，在标准遗传算法的基础上引入了免疫机制，并将其应用到周公宅一皎口水梯级水库优化调度中。计算结果表明，免疫遗传算法较好地克服了标准遗传算法收敛速度慢、易陷入局部极值、早熟等弱点。

英文摘要：

To improve the application effect of genetic algorithm in multi-objective optimization operation of cascade reservoirs,a new algorithm is developed by introducing the immune mechanism in standard genetic algorithm. Meanwhile, this multi-objective immune genetic algorithm was employed in the optimization operation of Zhougongzhai-Jiaokou cascade reservoirs. The results showed that the multi-objective immune genetic algorithm could overcome the disadvantages of standard genetic algorithm, such as low convergence speed, easily trapping into the local extre- mum and premature.
