Photovoltaic Generator modeling based on Look Up Table approach and implementation on STM32F407 board of the PerturbObserve algorithm based MPPT

摘要

The maximum power point tracking (MPPT) technique is very essential in photovoltaic (PV) systems. It is used in the case of solar battery charge controllers or in the case of the grid connected PV systems without storage facilities. In the latter case, MPPT main role is to ensure production of the maximum power from solar panels in order to inject it into the electrical distribution grid. In this paper we are interested to study the Perturb and Observe (P&O) algorithm based MPPT. For this purpose, a DC-DC boost converter is used with resistive receptor connected to its output. On the other hand, experimental data collected from a real PV module are used for PV Generator (PVG) modeling. This is done by implementing this data in the Lookup-table block which is the main component of the PVG model. This later can mimic the behavior of the real PV module. Simulations under MATLAB/Simulink are carried out in order to verify the performance of the studied MPPT. This latter is thereafter implemented on the STM32F407-VG Board to be validated using the PIL test.
