Resilience of district metered areas of water distribution networks

Abstract

This paper presents a methodology for the optimal partitioning of water distribution networks including a pump system and, in addition, it analyzes the performance of each solution. The partitioning algorithm is based on a twostage approach. The first one is formulated as a multi-objective optimization problem and consists on identifying the optimal network partition, namely those communities with nodes interconnected closely, while the connection between communities is sparse. The second one consists on determining the optimal location of isolation valves and flow meters by using the results established in the first stage. To analyze the performance of the solutions, the resilience index is evaluated by considering the demand increments for a fixed number of consumers
