Abstract
Optimal reservoir system management is particularly challenging because of the dimension of large water systems and conflicting management objectives. Additionally, such systems require a continuous adjustment process due to fluctuating natural water supply and demand. The method presented in this study is based on Model Predictive Control (MPC) and allows an anticipatory planning of the outflows in a reservoir system with the help of an embedded optimization procedure. This process relies on prognosed framework conditions for the hydrological situation and water demand on the basis of forecast data. Against the background of real-time reservoir system management and the associated ensuring the achievement of short-term management goals, practice-relevant optimization scenarios are presented to point out the advantages of a coordinated control of the reservoirs. Decision-making is based on the definition of a multi-objective optimization problem and differently weighted subgoals. Consistent standard values and quality criteria are used to assess the optimization model and the target function derived from the management objectives as well as to facilitate comparability of alternative solutions and model results.
