 Abstract: Maximum value of power can be derived from the solar PV system under the external discomposure and the variable solar irradiance using MPPT technique. Different literatures supplicate a number of MPPT techniques that can capture the power at the particular point known as maximum power point (MPP). This paper focuses on the grey wolf optimization (GWO) based MPPT technique and represents the comparison between PSO MPPT and the proposed GWO MPPT under same solar irradiance. A converter of boost type is implemented in this paper to rise the solar PV voltage. The suggested MPPT technique contributes meticulous and agile expelling for an isolated PV system. Comparisation between the two above mentioned MPPT methods is analyzed by using Matlab/ Simulink environment.Keywords : Grey wolf optimization (GWO), maximum power point (MPP), particle swarm optimization (PSO), photovoltaic (PV) system, maximum power point tracking (MPPT), Simulink.
