Description
Summary:SUMMARYIn this paper, we analyze and compare five distributed model predictive control (DMPC) schemes using a hydro‐power plant benchmark. Besides being one of the most important sources of renewable power, hydro‐power plants present very interesting control challenges. The operation of a hydro‐power valley involves the coordination of several subsystems over a large geographical area in order to produce the demanded energy while satisfying constraints on water levels and flows. In particular, we test the different DMPC algorithms using a 24‐h power tracking scenario in which the hydro‐power plant is simulated with an accurate nonlinear model. In this way, it is possible to provide qualitative and quantitative comparisons between different DMPC schemes implemented on a common benchmark, which is a type of assessment rare in the literature.
