| 摘 要： | 梯级水库优化调度是一种实现水资源合理分配与高效利用,提升水电系统运行管理水平的重要方法。改进肾脏算法为高效求解梯级水库优化调度提供了一条有效途径。肾脏算法是一种新颖的自然启发式优化算法,因其参数少、寻优能力强、稳健性高,已被广泛应用和认可。本研究对标准肾脏算法的寻优原理进行了阐述,针对该算法的种群多样性低和收敛速度慢缺陷,采用含缩放因子的运移策略和自适应调参策略对其改进,提出了改进的肾脏算法。以某梯级水库长期发电优化调度为例,计算结果表明:相比标准肾脏算法,改进的肾脏算法可使梯级水库多年平均发电量增加3.2亿kWh(增幅为4.03%)和弃水量减少17.54%。引入的改进策略有效克服了标准肾脏算法的早熟缺陷,提高了种群多样性和收敛速度。

| Abstract: | Cascade reservoir operation optimization plays a vital role in improving water allocation and promoting hydropower system management.The Improved Kidney Algorithm(IKA)provides an effective approach to the cascade reservoir operation model.The Kidney Algorithm(KA)is a novel nature-inspired optimization algorithm as well as widely applied and approved owing to its fewer parameters,superior search efficiency and robustness.In this paper,the optimization mechanism of KA is presented.To overcome the drawbacks of low diversity in population and inferior convergence,scaling factor-based movement strategy and adaptive strategy are introduced to configure the IKA.The feasibility and effectiveness of IKA is tested by solving cascade reservoir operation model.The results point out that:the IKA could significantly increase the hydropower generation(320 million kWh)of the cascade reservoir by 4.03%and largely decrease the spilled water volume by 17.54%in comparison to the KA.Mmeanwhile,the integrated strategies could effectively conquer the prematurity of the standard KA algorithm as well as lift the population diversity and algorithm convergence. |
