Hierarchical hydro power valley control: Validation on simulation platform

Abstract Hydro power valleys (HPV) are large scale interconnected systems. All plant operations have to comply with technical and environmental requirements concerning level, flow rate and power variations. A two-layer hierarchical MPC solution, designed to manage the large scale constrained and time delayed HPV, is tested on a simulation platform. The upper layer optimizes the power profiles on a one-day horizon with a coarse step size. The lower level refines the control for a shorter horizon and step size. Simulations show that the coordination is able to improve the maneuverability of the HPV.
