ABSTRACT

This paper develops a discharge allocation model for public water supply for a set of communities, considering available and planned reservoirs and interbasin transfer projects. Reservoir operation rules were defined for maximum water withdrawals in function of the storage volume over a period of 45 years, and then the discharges to be transported from the different sources to 18 locations were defined, minimizing the costs. Generalized Reduced Gradient and Particle Swarm Optimization algorithms were used in the optimization processes. The model was applied in the Agreste region of the state of Pernambuco, Brazilian semiarid. This region has the worst water balance in the entire country and three interbasin water transfer systems are under construction. Due to the interconnection among the systems, it will be possible to supply the communities from one or another source. The results showed that the optimized operation of the reservoirs can minimize water transfer and costs.

摘要

本文开发了一套社区公共供水的排放分配模型，考虑了可用和规划的水库和跨流域调水项目。水库运行规则根据 45 年的蓄水量定义了最大取水量，然后定义了从不同来源输送到 18 个地点的排放，从而最大限度地降低了成本。在优化过程中使用了广义降低梯度和粒子群优化算法。该模型应用于巴西半干旱地区伯南布哥州的 Agreste 地区。该地区是全国水平衡最差的地区，三个流域间调水系统正在建设中。由于系统之间的互连，有可能从一个或另一个来源向社区供货。结果表明，水库的优化运行可以最大限度地减少输水量和成本。
