Abstract

One of the problems in the field of water is its wastage in water supply networks due to water leakage due to high pressure. Therefore, keeping the pressure at a suitable range is necessary. The most effective equipment for this purpose is pressure relief valves and PAT. In this article, by linking the DE algorithm with the EPANET hydraulic solver, in the first step, by using the double-objective DE algorithm, the appropriate location of the pressure relief valves and its regulating pressure, as well as the optimal location of the reverse pump and the type of reverse pump, have been determined at the same time. In the second step, by using the DE single objective algorithm, by keeping the location of the pressure relief valves constant (resulting from the first step) and also keeping the location and type of PAT, the rotational speed of the pump and the regulating pressure of the pressure relief valve constant, to increase the production energy, Optimized in 24 hours. The obtained results showed that it is possible to provide 160 kilowatt hours per day of salable energy to the city power grid from the network.
