Experimental Comparative Study to Achieve the Maximum Power Point Tracking of a PV System

Abstract

This paper presents a comparison study in different techniques of maximum power point tracking (MPPT), which have been experimented and validated by simulation in the proposed PV system. The main aim of each MPPT technique is to enhance and optimize the output of photovoltaic (PV) array in dynamic weather conditions through an examination algorithm. Nevertheless, an optimized MPPT technique is described in many sides like achievement, software, precision, convergence velocity, and hardware naturalness. The gained experimental results for the MPPT techniques are compared using the Perturbation and Observation (P&O), Incremental Conductance (IncCond), Short Circuit Current (SCC), Open Circuit Voltage (OCV), and Constant Voltage (CV) at weather conditions variations. These methods were analyzed and their performance was estimated through using the Matlab/Simulink under different types of atmospheric conditions. These results show that the IncCond technique gives larger efficiency, at rapidly changing conditions than the other techniques.
