基于和声搜索算法的水库发电优化调度研究

为提高水电厂发电效益,综合运用和声搜索算法,提出单级水库的优化调度方法,即首先分析单级水库优化调度约束条件,然后以月末水位为自变量建立基于年发电量最大原则的水库优化调度模型,最后运用和声搜索算法模拟水库调度。实例应用结果表明,基于和声搜索算法的优化结果较多年实际最大发电量及遗传算法的优化结果分别提高了8.69%、1.55%。

Research on Optimal Operation of Reservoir Generation Based on Harmony Search

In order to improve the benefit of hydropower generation, harmony search algorithm was used to optimize reservoir scheduling. Firstly, the constraints of reservoir optimization scheduling were analyzed. Based on the principle of maximal annual power generation, the model of reservoir optimization scheduling was established by taking the water level in the end of month as independent variables. Finally, harmony search algorithm was to simulate the reservoir scheduling. Compared with the actual maximum power generation and the result obtained by GA, it shows that amount of electricity was increased 8.69% and 1.55%, respectively.
