| Sumario: | Economic aspects concerning the high costs related to energy requirements for managing complex water supply systems need a robust strategy, particularly considering the activation of pumping plants. Considering hydrological uncertainties, the definition of strategic rules can ensure energy savings and the well-timed activation of costly water transfers for shortage risk alleviation. The modelling approach has been developed aiming at defining strategic rules of pumps activation thresholds. It considers the need for seasonal variations of activation and the different costs of energy in diverse time slots, according to the usual cost rules adopted by the authorities. Starting with the traditional scenario analysis approach, a new algorithm has been developed considering a multiple-steps scenario optimisation implemented using GAMS interfaced with CPLEX solvers. The results should allow the water authority to establish a robust strategy for pumping activation to guarantee the fulfilment of water demands and to ensure an energy-saving policy. HIGHLIGHTS
This research aims to develop a new algorithm considering a multiple-steps scenario optimisation.;
The modelling approach defines optimal activation pumping thresholds associated with stored water levels in reservoirs, in order to guarantee a fulfilment of water demand and ensure an energy-saving policy.;
This approach allows the water system authority to establish a robust strategy to manage complex water supply systems.; |
