Photovoltaic module modeling and experimental power control using MPPT

Abstract EN

A Photovoltaic cell is a non-linear device.

In this paper, the DC current-voltage (I-V) characteristics of a photovoltaic module have been modelled.

Four points were used: the open-circuit voltage, the short-circuit current, and two points taken either side of the maximum power point.

In this paper a method for maximizing power using DC-DC converter based on the Constant voltage Tracking (CVT) combined with the Perturb and Observe (P&O) algorithm is presented.

A microcontroller is used as a support of the electronic control of converter and experimental tests are presented.
