摘要
为解决浆体管道梯级泵站在长距离输送中单泵流量均衡分配导致的泵站系统效率低与碳排放量大,且现有优化方法面对强耦合、多约束的梯级矿浆泵站多目标优化,容易陷入局部最优问题,提出了一种基于改进多目标常春藤优化算法(multi-objective ivy optimization algorithm, MOIVYA)的梯级矿浆泵站多目标优化调度方法。首先,构建包含矿浆流变特性与水力耦合约束的梯级泵站多目标优化模型,以系统效率最大化和碳排放最小化为目标函数;其次,针对常春藤算法(ivy optimization algorithm,IVYA)在求解梯级矿浆泵站多目标优化模型上的缺陷,设计多目标环境下的选择与多样性维护策略、多目标导向的个体生长与进化策略平衡解集收敛性与分布性,并基于多目标优化基准测试函数ZDT系列函数验证算法有效性及可行性;最后,将所提方法与非支配排序遗传算法Ⅱ(non-dominated sorting genetic algorithm Ⅱ,NSGA-Ⅱ)、多目标粒子群(multi-objective particle swarm optimization,MOPSO)和基于分解的多目标进化算(multi-objective evolutionary algorithm based on decomposition,MOEA/D)应用于云南大红山管道有限公司四级矿浆泵站工程案例开展对比实验研究。实验结果表明:基于MOIVYA优化方法在工程实例中较NSGA-II、MOPSO和MOEA/D有明显优势,优化后系统效率提高1.3%,日碳排放减少217.5 kg,可见该算法在复杂工程调度中的有效性与工程适用性,为工程实践提供了一种有效的解决方案。
Abstract
To address the low efficiency and high carbon emissions of the pump station system caused by the balanced distribution of single-pump flow in the long-distance transportation of cascade pump stations for slurry pipelines, as well as the problem that existing optimization methods tend to fall into local optima when dealing with the multi-objective optimization of cascade slurry pump stations with strong coupling and multiple constraints, a multi-objective optimal scheduling method was proposed for cascade slurry pump stations based on the improved ivy optimization algorithm (MOIVYA). First, a multi-objective optimization model for cascade pump stations was constructed, incorporating constraints on slurry rheological properties and hydraulic coupling, with the objective functions of maximizing system efficiency and minimizing carbon emissions. Second, aiming at the defects of the ivy optimization algorithm (IVYA) in solving the multi-objective optimization model of cascade slurry pump stations, selection and diversity maintenance strategies under a multi-objective environment were designed, along with multi-objective-oriented individual growth and evolution strategies to balance the convergence and distribution of the solution set. The effectiveness and feasibility of the algorithm were verified based on the ZDT series of benchmark test functions for multi-objective optimization. Finally, the proposed method was applied to a four-stage slurry pump station project case of Yunnan Dahongshan Pipeline Co., Ltd., and comparative experimental studies were conducted with the non-dominated sorting genetic algorithm Ⅱ (NSGA-Ⅱ), multi-objective particle swarm optimization (MOPSO), and multi-objective evolutionary algorithm based on decomposition (MOEA/D). Experimental results show that the MOIVYA-based optimization method has obvious advantages over NSGA-Ⅱ, MOPSO, and MOEA/D in the engineering case. After optimization, the system efficiency is increased by 1.3%, and the daily carbon emissions are reduced by 217.5 kg. It is evident that the algorithm is effective and applicable in complex engineering scheduling, providing an effective solution for engineering practice.
