    摘要:

    冰蓄冷空调优化控制方法中,基于智能算法的控制方法建模及求解复杂,可行性差,而工程常用的控制方法经济效益不佳。为解决上述问题,首先,以机组工况容量、蓄冰容量为约束条件,以日运行费用最小为目标函数,构建冰蓄冷空调优化运行的数学模型。然后,提出一种基于直接供冷电费贯序削减的冰蓄冷空调趋优控制方法,根据电价及直接供冷电费的排序安排制冰及融冰的时段,经迭代计算可寻得优化解。最后,与 GAMS软件优化结果相比较,验证该方法的有效性,与工程常用的控制方法相比较,验证所提的方法的经济性和可行性。

    Abstract:

    Among optimal control methods of icestorage air conditioning, control methods based on intelligent optimization algorithms are complicated to solve and lack of feasibility, and common engineering control methods are of poor economic benefit. To solve the above problems, in this paper, the mathematical model of the icestorage air conditioning optimal operation is built, in which the capacities of operation patterns and icestorage capacity are constraint conditions, and the minimum daily operation cost is the objective function. Then, an optimal control method based on the sequential reduction in direct cooling cost is proposed. Periods of storing or melting ice can be planned according to the arrangement of electricity price and direct cooling cost. Through several iterative computations, an optimal solution can be found. The proposed control method is of certain reliability by making a comparison with the optimal result obtained by GAMS. Compared with common engineering control methods, the proposed method has good feasibility and economical efficiency.
