Refining PSO Applied to Electric Energy Cost Reduction in Water Pumping - page 3

Results and Discussion

As a case study, the system designed by Carrijo (2004) is used to determine the optimal pump manoeuvres using a genetic algorithm. This system is located in the city of Goiânia, Brazil and is part of the delivery network for a population of approximately 1.2 million people. The demand nodes represent derivations to sectors of representative networks, and thus, the flow rates attributed to such nodes are the demands of the sectors delivered by each derivation (Carrijo, 2004). The figure below illustrates the topology of this network, and the tables display the physical and hydraulic characteristics of the network:
