Implementation of MPPT Technique in PV Array for a Varying Load by Modeling and Simulation

Abstract

This paper proposes the modeling and simulation of PV array employing the Maximum Power Point Tracking (MPPT) model describing how maximum power point can be achieved with the varying load. Due to environmental conditions and load variations, PV array is influenced and the efficiency of conversion becomes low. Hence it becomes necessary to detect the peak power to maximize the energy produced during load fluctuations by MPPT technique. The requirement of MPPT controller is to ensure that at maximum power output possible, the PV power generation system gives an output. This system consists of a PV array, MPPT controller, and a converter. The working of the PV array is described with an MPPT technique and without the MPPT technique. This paper shows variation of power with MPPT and without MPPT with the help of the graph.
