Comparative Analysis of Various MPPT-Techniques for Optimization of Solar-PVEC System

The paper aims to provide a comprehensive analysis of various MPPT Technique under various environmental condition. The photovoltaic array having non-linear power voltage characteristic and under non-uniform irradiances. It shows a many peaks which have many local peaks and one global peak. For getting a global peak among all local peaks, MPPT play an important role in PV system. Therefore a technique like maximum power point tracking (MPPT) is required to optimize the performance. Here the comparison of hill climbing perturb and observe (P&O) algorithm technique, incremental and conductance (I&C) control algorithm, the drift free P&O algorithm technique are discussed in detail with simulation and simultaneously some other intelligent control techniques comparison are given briefly which help the researcher to ease in selecting the appropriate algorithm for specific application.
