, 2018 La commande MPPT (Maximum power point tracking) permet de chercher le point de fonctionnement optimal du générateur photovoltaïque suite à des variations climatiques et de charge. Son principe est basé sur la variation automatique du rapport cyclique du convertisseur statique (CS) pour maximiser continuellement la puissance du générateur photovoltaïque

Etude et réalisation d'un circuit de commande avec MPPT d’un hacheur pour système photovoltaïque
, 2015 Dans ce mémoire nous allons faire l’étude, la modélisation et l’optimisation d’un générateur photovoltaïque fonctionnant avec un hacheur élévateur. Cette étude porte sur l’implémentation de différents algorithmes pour le suivi du point de puissance maximale tel que par la méthode Mikihiko Matsui, la méthode perturbation et observation et la méthode ...

Etude par simulation du fonctionnement d’un système photovoltaïque menu d’une commande MPPT
, 2016 Ce travail consiste en la description et la modélisation d’un système photovoltaïque, il est constitué d’un générateur (PV) associé à un hacheur élévateur relié à une charge. Une caractéristique importante des panneaux solaires est que la puissance maximale disponible est fournie seulement en un seul point de fonctionnement défini par une tension et un

, 2014 Une connexion directe entre une charge et un générateur Photovoltaïque et/ou éolien pose beaucoup de problèmes concernant l’optimisation de la puissance, l’influence sur le rendement du système et la mauvaise adaptation. En plus, si cette charge est une batterie, le bon fonctionnement et la protection de cette dernière ne seront jamais assurés par ...

In the era of sustainable development, photovoltaic (PV) technology has shown significant potential as a renewable energy source. Photovoltaic generators (GPV) have a non-linear current-voltage characteristic, with a maximum power point (MPP) characterized by an optimal voltage, and depends on environmental factors such as temperature and irradiation ...

In this paper we have analysed in Pispce and in experiments the operation of a PV system formed with a converter DC-DC of the buck type, MPPT command and Circuit Command buck (CCB). We have showed that the CCB circuit commands the switch of the DC-DC converter and the PV panel operates at its optimal voltage.
