Low-frequency current oscillations and maximum power point tracking in grid-connected fuel-cell-based systems / Giustiniani, Alessandro in IEEE transactions on industrial electronics, Vol. 57 N° 6 (Juin 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 6 (Juin 2010) . - pp. 2042 - 2053 Titre : Low-frequency current oscillations and maximum power point tracking in grid-connected fuel-cell-based systems Type de document : texte imprimé Auteurs : Giustiniani, Alessandro, Auteur ; Petrone, Giovanni, Auteur ; Spagnuolo, Giovanni, Auteur Article en page(s) : pp. 2042 - 2053 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Fuel  cell  (FC)  Low-frequency  ripple  rejection  Maximum  power  point  (MPP)  tracking  (MPPT)  Single-phase  inverter  control Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : The study of a double-stage single-phase inverter for fuel-cell-based applications is proposed in this paper. A novel control strategy aimed at reducing the low-frequency oscillations of the fuel-cell (FC) current in order to guarantee the FC safety operating conditions is proposed. The reduction of such oscillations increases the FC lifetime and avoids high mechanical stress of the membrane and unnecessary consumption of reactants. Furthermore, it allows one to design a strategy for extracting the maximum power from the FC stack with a total control of the concentration losses. Simulation and experimental results confirm the effectiveness of the proposed approach.

A technique for improving P&O MPPT performances of double-stage grid-connected photovoltaic systems / Femia, Nicola in IEEE transactions on industrial electronics, Vol. 56 N° 11 (Novembre 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 11 (Novembre 2009) . - pp. 4473 - 4482 Titre : A technique for improving P&O MPPT performances of double-stage grid-connected photovoltaic systems Type de document : texte imprimé Auteurs : Femia, Nicola, Auteur ; Petrone, Giovanni, Auteur ; Spagnuolo, Giovanni, Auteur Article en page(s) : pp. 4473 - 4482 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Inverter  Maximum  power  point  tracking  Photovoltaic  power  processing  systems Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : In double-stage grid-connected photovoltaic (PV) inverters, the dynamic interactions among the DC/DC and DC/AC stages and the maximum power point tracking (MPPT) controller may reduce the system performances. In this paper, the detrimental effects, particularly in terms of system efficiency and MPPT performances, of the oscillations of the PV array voltage, taking place at the second harmonic of the grid frequency are evidenced. The use of a proper compensation network acting on the error signal between a reference signal provided by the MPPT controller and a signal that is proportional to the PV array voltage is proposed. The guidelines for the proper joint design of the compensation network (which is able to cancel out the PV voltage oscillations) and of the main MPPT parameters are provided in this paper. Simulation results and experimental measurements confirm the effectiveness of the proposed approach.
