P&O algorithm based MPPT technique for solar PV system under different weather conditions

Abstract

Maximum power point trackers (MPPTs) play a significant role in extracting power from photovoltaic (PV) generators as they draw the maximum power output (MPP) available irrespective of continuous changes of temperature and irradiation conditions. Therefore, in the efficiency of the global PV system, MPPTs take the foremost place. A DC-DC boost converter boosts the DC voltage generated by the photovoltaic system. Various MPPT algorithms pilot these trackers out of which Perturb and Observe (P&O) technique is emphasised upon as it is highly simple to implement within electronic programmable circuits. This paper incorporates into the model various environmental factors to study the behaviour of the PV panel output of which is controlled by MPPT trackers. The components of the proposed system with their function are followed by a simulation of a sample system in MATLAB/Simulink software to verify the advantages of proposed integrated system.
