“…The experimental results presented in this paper regard both the dynamic characterization of a 4.5 kW PEM FC and of a 100 Ah lead-acid battery storage system. In this respect, the obtained results appear to be an interesting complement of those recently presented in the literature by other Authors (e.g., Uzunoglu, et al, 2007 andTang, et al, 2010) that are mainly focused on the analysis of the FC characteristics.…”

Abstract:The paper presents an automatic power management system (PMS) designed for the on-line operation of an experimental low voltage microgrid equipped with two power supplies, a kW-class fuel cell (FC) and a photovoltaic (PV) module emulator, along with a 100-Ah battery storage system, all connected to a 230 VAC node. The connections of the various components to the common AC bus make use of power inverters with specific functionalities: the FC inverter controls the power production taking into account the FC limitations and requirements, the inverter of the PV emulator tracks its maximum power operating point, whilst, in islanded operating conditions, the bidirectional converter of the battery controls the voltage and frequency of the AC node. The AC node feeds electric active and reactive loads able to reproduce arbitrary and programmable profiles. The automatic PMS is implemented in a real time microcontroller and it is able to provide both the microgrid monitoring and supervisory control during grid-connected and islanded conditions and the FC power scheduling throughout various operating modes. The paper describes also the experimental investigation aimed at assessing the dynamic characteristics of the stand-alone microgrid equipped with the developed PMS.

“…In the light of these considerations, it becomes clear that, in order to optimize efficiency, reliable control systems ensuring extended stability and performance, as well as robustness against model uncertainties and external perturbations are of critical importance for PEMFC success and future industrial developments [6], [7]. In particular, the oxygen stoichiometry control is a challenging problem [8], [9], [10], since it deals with system non-linearities and must be able to optimize the overall conversion efficiency in the entire operation range, avoiding performance deterioration together with eventual irreversible damages in the polymeric membranes due to oxygen starvation.…”

Abstract-The article addresses the LPV control of a PolymerElectrolyte Membrane Fuel Cell (PEMFC). In order to optimize efficiency, PEMFCs require reliable control systems ensuring stability and performance, as well as robustness to model uncertainties and external perturbations. On the other hand, PEMFCs present a highly nonlinear behavior that demands nonlinear and/or adaptive control strategies to achieve high performance in the entire operating range. Here, a linear parameter varying (LPV) gain scheduled control is proposed. The control is based on a piecewise affine LPV representation of the PEMFC, a model that can be available in practice. In order to deal with the saturation of the control action, an LPV anti-windup compensation is also proposed. The complete control strategy is applied to several experimental practical situations in a laboratory fuel cell system to evaluate its performance and the reliability of the proposed algorithms.Index Terms-Linear parameter varying systems; gain scheduled control; anti-windup; PEM fuel cells; oxygen stoichiometry.

“…In fact, the production of hydrogen and its subsequent use in fuel cells was proven to be technically viable under dynamic solar irradiance and dynamic load conditions [25]. For instance, the proton-exchange membrane (PEM) fuel cell technology emerged to be one of the promising technologies that can be favourable for use in residential applications, due to the fact that it is quite simple, is easy to start up, can adjust efficiently to variable power demands, operate silently at low temperatures (i.e.…”
