Implementation and Comparative Analysis of P&O and INC MPPT Method for PV System

Different types of techniques have been used for tracking the MPPT of PV system such as perturb and observe and incremental conductance, etc. The incremental conductance MPPT tracking techniques is complex but more efficient than P&O of PV system under specified atmospheric conditions. Therefore, the aim of this work is to present comparison between P&O and INC maximum power point tracking techniques. This paper presents the implementation and comparison of performances with respect to output parameters for P&O and INC MPPT algorithms. The comparison shows INC technique is more efficient and offers a fast tracking speed for the MPPT of a PV array. The modeling of the system is executed with MATLAB/SIMULINK software.
