Conception, réalisation et caractérisation d'un système photovoltaïque menu des commandes de contrôle et d'acquisition numériques

In this paper, we present the results concerning the design, the realization and the characterization of a photovoltaic system (PV), medium power (100 W), equipped with a MPPT control, a controller battery , a system for tracking the sun and a system for the acquisition and supervision, based on a microcontroller. The experiment of each block, show that: (1) The digital MPPT control convergence instantly operating point of the PV panels around the maximum power point, independently of rapid changes in the illumination and the load, (2) Regulating the charging and discharging of batteries is carried using an algorithm including the specificities of the PV system, (3) The need for a sun tracker to increase the power supplied by the PV panels. All the results show the reliability of a complete PV system and an operation exploiting the maximum of solar energy. [PUBLICATION ABSTRACT]
