Modelling and Simulation of Maximum Power Point Tracking Algorithm based PV Array and Utility Grid Interconnected System

Abstract

Depletion of non-renewable energy sources with the increasing demand in electricity and also to avoid islanding condition an efficient and sustained source of energy becoming mandatory. This paper focuses on mathematical modeling and simulation of PV module with boost converter interconnected with utility grid. MPPT algorithm named Incremental conductance (Inc. Cond.) technique is implemented in boost converter to extract maximum possible power from PV module which in turn depends on solar irradiance and temperature. The output from converter is fed to real time utility grid. This work lead to utilize the renewable solar energy at a large scale by interconnecting PV module and utility grid while extracting constant maximum power from module. This paper will review existing approaches on MPPT algorithms. PV module of 100kw is converted into AC and fed to utility grid. PV and IV characteristics are obtained by modeling mathematically for data sheet SunPower SPR-305E-WHT-D in MATLAB code. The output waveforms for power output from PV module before and after implementation of MPPT algorithm are analyzed through MATLAB Simulation.
