Implementation of MPPT Algorithm for Single-Stage Grid-Connected Photovoltaic system by using incremental conductance method

Abstract

This paper presents simulation and implementation of maximum power point tracking algorithm for single stage three-phase grid-connected PV system by using incremental conductance method. The maximum efficiency is realized when PV works at its maximum power point, which is contingent on irradiation and temperature. Since the irradiation and temperature always change with time, a PV system which able to track the maximum power point needs to be established to produce more energy. the IC method shows a superior performance, lower oscillation and it took 3second to match MPP that abest time to give stability to the system. the control strategy is supported out using MATLAB/Simulink and experimentally validated with a dSPACE MicroLabBox controller.
