Advanced coordinated control for a Hydro-Power Valley
Résumé
This paper aims at improving control systems for hydro-power production, by combining Model Predictive Control techniques with Decomposition/Coordination methods for a global optimization over a whole Hydro-Power Valley. It first recalls the Model Predictive Control formulation for a centralized solution presented as a reference, and emphasizes the possible use of explicit solutions in the considered problem, making easier its practical use. It then highlights the further interest of such solutions in a Decomposition/Coordination approach, allowing to reduce the computational cost even more with a purpose of real-time implementation, and at the same time to take advantage of the distributed nature of the whole system under consideration. The results are illustrated and compared on the basis of a real-data-based case-study provided by French group EDF
