<p>A system for optimizing operation of a water network comprises at least one data storage unit (23) for storing a hydraulic model as well as at least one operational constraint of the water network (17), where the hydraulic model represents the dependence of heads and flows in the water network on an operational state of at least one actuating unit (20) of the water network and on an expected water demand, at least one processing unit containing an optimizing unit (OP), where the optimizing unit is adapted to generate at least one operational configuration information for the at least one actuating unit by minimizing an objective function of an optimization problem, where the optimization problem is based on the hydraulic model, at least one output interface (18) for providing the at least one operational configuration information to the at least one actuating unit. In order to be able to operate the water network with a reduced lower level bound of a water storage facility, the at least one processing unit further contains a scenario generating unit (SG) for generating a finite set of scenarios in the form of possible realizations over time of the expected water demand and/or of the operational state and/or characteristics of the at least one actuating unit and/or of at least one parameter of the hydraulic model, where the finite set of scenarios is based on probabilistic information on the uncertainty of these variables. The optimizing unit is adapted to minimize the objective function of the optimization problem by performing stochastic optimization, where the optimization problem further takes into account the objective function for representing at least one undesired side effect of operating the at least one actuating unit, the at least one operational constraint and the finite set of scenarios.</p> |
