Abstract

The problem considered in this paper consists of the reduction of electrical energy costs necessary for the operation of hydraulic pumps, which are used to collect water from artesian wells or from a Water Treatment Station to fill water tanks located in many districts of a city. The water is then supplied by gravitational force. Because the cost of electrical energy varies throughout the day, a pump running schedule is necessary. The problem consists of determining when the pumps must be on and when there must be water transfer among tanks to ensure that the demand of each water tank be supplied, thereby minimizing the costs of electrical energy. This problem was modeled as an integer linear optimization problem, and a heuristic solution to the problem is proposed. Computational experiments show the efficiency of the heuristic and highlight how the approach can be used to analyze the impact of changes in the infrastructure of the water supply system.
在水的收集、储存和分配规划中优化电力成本
本文考虑的问题包括减少液压泵运行所需的电能成本,这些液压泵用于从自流井收集水或从水处理站收集水以填充位于城市许多地区的水箱。水是由重力提供的。由于电能的成本在一天中变化,因此泵的运行计划是必要的。该问题包括确定何时必须开启水泵,何时必须在水箱之间进行输水,以确保每个水箱的需求得到满足,从而使电能成本最小化。将该问题建模为一个整数线性优化问题,并提出了一种启发式求解方法。计算实验表明了启发式方法的有效性,并强调了该方法如何用于分析供水系统基础设施变化的影响。
