Leakage control of multi-source water distribution system by optimal pump schedule

The main aim of optimal schedule of traditional water distribution system is to reduce energy consumption, without consideration of minimizing network leakage. This research is on the premise of meeting water demand, pressure and quality, at same time taking the minimization of network leakage and power consumption as the optimization objectives, taking pump and valve opening and closing as decision variables, to build leakage control model of multi-source water distribution system by optimal pump schedule. On the basis of this model, the partition scheme and pump scheduling of water supply system are determined; the NSGA-II algorithm is used for solving the optimisation problem. By applying it to practical water supply network in HD city, the results showed thatthis method can simultaneously reduce power consumption and network leakage.
