Investigating the Utility of Perturbation and Observation, Incremental Conductance and Grey-Wolf MPPT Techniques for ON-Grid PV System Under Fluctuated Environmental Conditions

Abstract

This paper investigates the performance of the ON-Grid solar PV system using three different Maximum Power Point Tracking (MPPT) techniques (Perturbation and Observation (P&O), Incremental Conductance (I.C.) and Grey-Wolf technique). The performance of the MPPT techniques has been scrutinized while the change in the external environment such as partial shading conditions and the variation of the temperature has been applied. The purpose of this research is regulating the output voltage and output power with a very high-speed response. A comparison between the proposed MPPT techniques has been discussed and it is concluded that the Grey-Wolf MPPT technique ensures a reduction in the time response by 96% and 71.4% corresponding to the I.C. and P&O techniques respectively. All the simulations have been implemented through the MATLAB/Simulink computer program.
