| 摘 要： | 水库优化调度是水资源系统工程的一个典型,其实质是一个非线性的不等式约束优化问题,然而现行的求解方法中针对离散精度和复杂约束处理两个问题一直考虑不足,相关方面的研究也较少。将连续域寻优的粒子群算法引入到水资源系统工程中,建立水库调度的PSO优化模型,避免因离散而引起的寻优瓶颈,并针对传统粒子群算法的趋同性问题和复杂约束问题,提出退火罚函数法和混沌变异因子法,使改进后的粒子群能更有效地解决水库调度问题。通过实例分析,验证该方法的可靠性,为水库调度提供了一种新的求解途径。

| Abstract: | The calculation of reservoir optimal operation is discussed in the paper virtually as an optimization of nonlinear function with constraints.After some comparison and analysis,it is found that discreteness accuracy and constraint disposal have always been given scant attention in the extant calculating methods,and that the related research is also sparse.In order to overcome these defects,the particle swarm optimization algorithm with optimizing ability in the continuous field,is proposed to build an optima... |
