    摘要:

    中央空調系統并聯(lián)冷水機組系統能耗非常大,如果操作不當,能耗會(huì )大大增加。針對OCL問(wèn)題提出了一種求解連續非線(xiàn)性?xún)?yōu)化問(wèn)題的改進(jìn)鯨群優(yōu)化算法,首先,為使后續迭代尋優(yōu)的搜索空間更精確,運用混沌映射初始化種群,使初始解均勻遍布解空間。其次引入變異指數對收斂因子進(jìn)行改進(jìn),平衡了局部勘探和全局勘探的關(guān)系。之后引入正弦和余弦使算法收斂到全局最優(yōu)解,防止了算法過(guò)早收斂,提高了算法的收斂精度。最后,通過(guò)兩個(gè)典型的案例來(lái)評估IWOA算法的性能,并將其與應用于OCL問(wèn)題的其他優(yōu)化算法進(jìn)行了比較。結果表明,IWOA算法是解決OCL問(wèn)題的有效方法。此外,算法性能的比較顯示,IWOA算法在收斂速度和電能消耗方面相比于其他應用于OCL問(wèn)題的優(yōu)化方法提供了更好的解決方案。

    Abstract:

    Central air-conditioning system parallel chiller system energy consumption is very large, if improper operation,energy consumption will be greatly increased.An improved whale population optimization algorithm is proposed to solve the continuous nonlinear optimization problem of OCL problem.Firstly, in order to make the search space of the subsequent iteration more accurate, the chaotic mapping is used to initialize the population,so that the initial solutions evenly spread across the solution space. Secondly, the variation index is introduced to improve the convergence factor and balance the relationship between local exploration and global exploration.After that, sine and cosine are introduced to make the algorithm converge to the global optimal solution,which prevents premature convergence of the algorithm and improves the convergence accuracy of the algorithm.Finally, the performance of IWOA algorithm is evaluated by two typical cases and compared with other optimization algorithms applied to OCL problems.The results show that IWOA algorithm is an effective method to solve OCL problem.In addition, the comparison of algorithm performance shows that IWOA algorithm provides a better solution than other optimization methods applied to OCL problems in terms of convergence speed and power consumption.
