In this paper, a performance comparison among three well-known stochastic model
predictive control approaches, namely, multi-scenario, tree-based, and chance-constrained
model predictive control is presented. To this end, three predictive controllers have
been designed and implemented in a real renewable-hydrogen-based microgrid. The
experimental set-up includes a PEM electrolyzer, lead-acid batteries, and a PEM fuel
cell as main equipment. The real experimental results show significant differences from
the plant components, mainly in terms of use of energy, for each implemented technique.
Effectiveness, performance, advantages, and disadvantages of these techniques
are extensively discussed and analyzed to give some valid criteria when selecting an
appropriate stochastic predictive controller.Ministerio de Economía y Competitividad DPI2013-46912-C2-1-RMinisterio de Economía y Competitividad DPI2013-482443-C2-1-
