Madsen and J. H0st-Madsen DHI Water Environment Denmark Long Le Ngo Water Resources University Vietnam D. Rosbjerg Technical University of Denmark A combined flow prediction and control system is described for the optimization of multi-purpose reservoir operation. The system integrates a numerical model for simulation of river flow and reservoir operation with an optimization tool. The procedure is applied for optimization of reservoir operation rule curves of the Hoa Binh reservoir in Vietnam considering hydropower production and downstream flood control and demonstrates that it could be possible to generate an extra 210 GWh year on average. Reservoir operation is a complex problem that involves a number of often conflicting objectives including flood control hydropower generation water supply for various users navigation control and so on. Traditionally fixed reservoir rule curves have been used for guiding and managing the reservoir operation. These curves specify reservoir releases according to the current reservoir level hydrological conditions water demands and time of the year. Established rule curves however are often not very efficient for balancing the demands of the different users. Moreover reservoir operation often includes subjective judgements by the operators. Thus there is a potential for improving reservoir operating policies and even small improvements can lead to large benefits. For optimization of reservoir operation procedures based on coupling simulation models with numerical search methods have been developed. In this paper the MIKE 11 modelling system developed by DHI Water Environment is adopted for simulating the flow in the river system and reservoir operations. The structure operation module in MIKE 11 allows for the implementation of complex control strategies .
