Comparative Study of MPPT Controllers for PV System Implemented in the South-West of Algeria

The photovoltaic array characteristic is a non-linear curve that the maximum power point varies depending on the fluctuation of the solar radiation and temperature; however the energy transfer from the generator to the load requires an adapter circuit allowing the stabilization of system controlled by a command based on specific algorithm, in this paper we want to analyze the electrical performances of DC-DC converter assisted by MPPT control in comparison between Perturb & Observe,PID and fuzzy logic control (FLC) to loading a storage battery .Our contribution is to explain the precision, the rapidity and the stability of the Stand-alone Photovoltaic System (SPV) under each MPPT control, implemented in the south west of Algeria.
