摘要
采用改进的动态规划算法对定速泵排水泵站的优化调度问题进行求解,考虑了峰谷分时电价制度对电费的影响,以一座配有两台定速泵的排水泵站为例,首先建立了该泵站的物理模型和动态规划模型,然后构造了改进动态规划算法并详细分析了该算法的主要思想和求解算法时的编程思路,最后计算出了双泵控制下的最优启停控制序列和优化结果,并将该结果与传统控制下的运行结果进行了比较分析.与其他的优化算法相比,其计算时间大大缩短,而且能效优化效果明显.
An improved dynamic programming algorithm is proposed for the optimal operation scheduling of a drainage pumping station with the time-sharing electricity price.A pump station equipped with two fix-speed pumps is employed as a case study.The physical model of the pump station is built firstly;and then,an improved dynamic programming algorithm is proposed;and its main ideas and programming procedures are analyzed.Finally,the optimal schedule sequence of the two pumps is calculated.The optimization results are compared with the traditional operating strategies;and the significant economical benefits are obtained for the drainage pumping station with the proposed algorithm.
