Summary: This paper proposes a clustering-based model predictive controller to optimize the heat transfer fluid (HTF) flow rates in solar parabolic trough plants. The hierarchical approach consists of two layers: a bottom layer of model predictive control agents and a top layer that dynamically partitions the loops into clusters. The dynamic clustering reduces the variables to be coordinated and speeds up the computations. Numerical results are provided for a 10-loop and an 80-loop plant.
