Optimization of the operation of water distribution systems with emphasis on the joint optimization of pumps and reservoirs

Abstract

The high costs generated by water supply systems’ pumping stations has generated great concerns regarding concessionaire companies in the sector. Improvements to increase these systems’ efficiency and consequently reduce electricity costs have been the objective of several researchers and technicians responsible for the sector. Given the many elements that compose these systems, finding the best operational rules is frequently a complex activity. In this context, the present work includes an optimization model based on genetic algorithms that combine the efficient use of reservoirs with the best operational rule for activating pumping systems. The results indicate that with better use of the water storage infrastructure, it is possible to reduce costs for the electricity of the system as a whole. HIGHLIGHTS Optimal pump scheduling in water distribution systems was studied.; The efficient use of reservoirs is considered in the optimization.; Results show the model’s good performance compared to others.;
