Abstract

In this paper a new approach to determine the maximum power point (MPP) of a solar PV system is proposed. It is based on the Artificial Neural Network (ANN) technique combined with an improved perturb and observe (P&O) method. The developed ANN delivers the optimal voltage in order to adjust the DC–DC converter duty cycle used by the P&O algorithm. The simulation results using MATLAB_SIMULINK showed that the new approach gives a power efficiency of the PV system more than 97 % in both stable and rapidly changing conditions. The improved P&O-ANN MPPT method has also been compared with the conventional P&O technique. In stable weather conditions the efficiency is slightly better. But under rapidly changing conditions the new method leads to a better PV system average power efficiency by an amount of 3 %. The oscillations around the MPP and the time response are also reduced.
