| Titre : | Commande d’une Centrale PV Connectée au Réseau Via un Onduleur à Source d’Impédance | | Type de document : | texte manuscrit | | Auteurs : | Ahmed Madani Boulehia, Auteur ; Siham Babaghayou, Auteur ; Lakhdar Mokrani, Directeur de thèse | | Editeur : | Laghouat : Université Amar Telidji - Département d'électrotechnique | | Année de publication : | 2022 | | Importance : | 89p. | | Note générale : | OPTION : Électrotechnique Industrielle | | Langues : | Français | | Résumé : | This memoir presents a study concerning a photovoltaic system connected to the electrical
network via an impedance source inverter (Z-Source). This power conditioner allows the PV generator
voltage boosting and the control of the powers injected into the grid at the same time. The first part is
devoted to the photovoltaic generator, its components, its operating principle, its characteristics and its
modeling. Next, the Z-Source inverter has been compared to the voltage and current source inverters.
Then, the different topologies and control strategies of this power conditioner have been presented. In
addition, the MPPT control by the Conductance Increment (CI) method as well as the control of the
powers injected into the grid, through the adjustment of the DC bus voltage and the active and reactive
currents, have been described and elaborated. This PV plant has been simulated using
MATLAB/SIMULINK software. Several simulations have been carried out in order to show the
contribution of the Z-Source converter to improve the quality of energy injected into the grid for
different operating conditions corresponding to variable light intensity and temperature. | | note de thèses : | memoire de master |
