Title: Receding horizon control for water resources management Authored by: Castelletti, A., Pianosi, F. and Soncini-Sessa, R. Abstract:
Integrated Water Resources Management (IWRM) is recognized worldwide as the reference paradigm to meet society's long-term needs for water resources while maintaining essential ecological services and economic benefits. In previous publications (Castelletti and Soncini-Sessa, 2006 and Castelletti et al., 2008), the authors
have already insisted on the need for a procedural approach to make the IWRM paradigm truly operational; they have emphasized the role played by dynamic optimization in rationalizing and facilitating the selection by the decision maker of a best compromise planning alternative. When planning alternatives also include management policies, as in the case of the water reservoir networks considered in this paper, the best compromise off-line policy resulting from the planning exercise has to be actually implemented in the daily management of the system. Here again, dynamic optimization may play a central role, as it can be adopted on-line to improve the performance of the off-line policy by exploiting any new useful information available
in real time (e.g. inflow predictions, a power station being temporarily out of service, etc.). In this paper this approach is explored through a real-world case study of a simple reservoir system. The off-line management policy computed in a previous planning process is refined on-line with a receding-horizon control scheme combined with an inflow predictor. The results yield indications that the approach can provide significant
advantages to cope with extreme events, particularly those occurring in unusual periods of the year
