Comparative Analysis of MPPT Techniques in Grid-Connected and Stand-alone PV System

Abstract

Solar energy is recognized as most promising energy source. MPPT technique is the optimized technique to track the MPP and to extract the maximum power out of PV panel under all available condition. There are different MPPT techniques available for different applications, and these techniques are used to get the maximum output power regardless of the existing conditions such as solar irradiance, and temperature. The paper discusses about various MPPT strategies in stand-alone and grid-connected PV system considering some features. There is a brief overview on various conventional methods and modern techniques, and all the methods are compared considering the significant key features.
