Advanced Solutions in Water Networks Pump and Valve Scheduling • Hydraulic model-based generation of optimal set-point schedules for pumps, valves and reservoirs in order to achieve optimal results following the objective function mainly to reduce pumping and water source costs • Takes into account the supervisory / global level to generate optimal schedules • Uses inputs such as demand forecasting and energy tariffs in order to calculate future schedules J = min ∑ pumping cost + ∑source cost + pumps sources ∑ demand nodes leakage cost © ABB | 24
Advanced Solutions in Water Networks Model Simplification • For Supervisory Pressure Control as well as Pump and Valve Scheduling, a hydraulic optimization model is needed which is derived from a hydraulic simulation model • As the simulation model is typically too large and detailed for optimization purposes in terms of number of nodes, pipes, valves and model accuracy, it is required to reduce the number of objects and to keep only those needed for the optimization © ABB | 25
