Optimum location for energy recovery and leakage reduction in water distribution networks

Abstract The excess pressure in water distribution networks (WDNs) can be utilized to reduce leakage and produce energy by installing recovery devices (ERDs) like microturbines or pumps-as-turbines. major challenge adopting ERDs pipe is locate the optimum location for their placement. An optimization procedure proposed this work find locations of (ER) reduction (LR). method based on Rao algorithm, written Python, coupled an EPANET-implemented hydraulic model. With optimal ER 543.46, 648.24 154.58 kWh/day LR 61.1, 13.6 6.8%, three benchmark – 5-node, 25-node 46-node network serve as basis validating approach which converges best solution only 2,000, 4,000 10,000 function evaluations. For large networks, solutions with two ideally located gave higher than imperfectly devices. This methodology verified give applied any regardless size location. made it easier analyse potential WDNs promotes use sustainable management methods.
