- 摘要:
- 为了在保障供水压力的前提下实现节能降耗的目标，探讨了改进增量动态规划法在供水管网优化调度中的应用。使用EPANET构建了供水厂网水力模型，采用K-Means聚类算法优化边界数据，并通过粒子种群（PSO）算法对模型进行率定。基于现状经验调度方案，构建了多目标调度函数及约束条件，通过改进增量动态规划法，对出厂压力步长进行动态优化并寻找到更优的调度方案。结果表明，改进增量动态规划法在供水管网优化调度中具有较好的实用性，不仅使LA市城区用户端供水压力全部达标，还降低了漏损率，相比现状经验调度显著提高了供水效益。
- Abstract:
- This study investigated the application of improved incremental dynamic programming method in the optimization of water supply network scheduling, to achieve the goal of energy saving and consumption reduction while ensuring water supply pressure. The hydraulic model of waterworks and pipe network was constructed using EPANET. The boundary data were optimized through the K-Means clustering algorithm, and the model was subsequently calibrated using the particle swarm optimization (PSO) algorithm. The multi-objective scheduling function and constraint conditions were systematically formulated based on the current empirical scheduling approach. Through the improved incremental dynamic programming method, the pressure step of waterworks was dynamically optimized, leading to the identification of an improved scheduling strategy. Improved incremental dynamic programming method demonstrated excellent practicability in optimizing water supply network scheduling. It not only ensured that the water supply pressure throughout the LA city fully complied with the standard but also effectively reduced the leakage rate. Compared to the current empirical scheduling methods, improved incremental dynamic programming method achieved a significant improvement in water supply benefits.
