摘要
水库群防洪调度是复杂多维度、多变量、多阶段非线性优化问题,研究高效稳定的智能优化方法对提高流域整体防洪能力有着重要作用。鲸鱼优化算法(WOA)是基于鲸鱼捕食行为的新颖智能算法,但在求解防洪调度问题时存在早熟收敛、易陷入局部最优等不足。为此提出自适应变异鲸鱼优化算法(AWOA)求解水库群防洪优化调度问题:利用改进混沌策略保障初始调度方案分散均匀性,采用反向震荡变异策略增加全局搜索能力,通过自适应权重策略实现局部精细勘探。经典测试函数和西江流域典型调度场景应用表明:该方法在不同场景下均具有显著削峰效果,具有收敛速度快、搜索精度高等优势,为求解水库群防洪调度问题提供了新型实用方法。
Flood control operation of reservoir groups is a complex nonlinear optimization problem involving multiple dimensions,variables,and stages,and plays a vital role in developing efficient and stable methods to enhance the overall flood control capacity of river basins.Whale optimization algorithm(WOA)is an innovative evolutionary algorithm inspired by whale predation behaviors.However,when it is employed to solve flood control operation,problems of premature convergence and proneness to fall into local optimum will occur.To this end,this paper proposes an adaptive-mutation whale optimization algorithm(AWOA)for solving the flood control operation of reservoir groups.In AWOA,an enhanced chaotic strategy is adopted to ensure the dispersion and uniformity of the initial operation scheme.Secondly,a reverse oscillation mutation strategy is utilized to enhance the global search ability.Finally,an adaptive weight strategy is leveraged to realize local fine exploration.Classical test functions and typical operation scenarios in West River show that the proposed method has significant peak shaving effects under various scenarios.With a fast convergence rate and high search accuracy,AWOA provides a novel and practical method for solving the flood control operation of reservoir groups.
