A Comparative Study of Perturb and Observe (P&O) and Incremental Conductance (INC) PV MPPT Techniques at Different Radiation and Temperature Conditions

The biggest challenge in the solar system is to extract maximum output powerfrom photovoltaic (PV) panels under different radiation and temperatureconditions. This paper presents a comparative study between perturb observe(P & O) incremental conduction (INC) algorithms. These are most popularalgorithms for tracking PV extracting power point(MPP) climate conditions. studied MPPTtechniques have been investigated by simulation using MATLAB/Simulink. Thesimulation includes boost converter, which increases panel voltage bycontrolling duty cycle. obtained results show that P O performanceclose MPP constant test conditions (STC) better than variableconditions due oscillation. In contrast, performance of INC algorithm isbetter terms speed reach MPP, accuracy, quality underchanges temperature
