Modeling and simulation of solar PV module for comparison of two MPPT algorithms (P&O & INC) in MATLAB/Simulink

Abstract

This paper introduces a procedure for the modeling of a Photovoltaic (PV) cell and the application of“maximum power point tracking (MPPT)”in step-by-step with MATLAB/Simulink. The model of one diode is used to explore the characteristics of I-V and P-V curves of 60W PV module. Due to the non-linear and time-varying of PV characteristics, the generated power of the PV is continually varying with atmospheric conditions like temperature and irradiation, the MPPT technology is very important to chase“maximum power point (MPP)”on the P-V curve to obtain maximum output power from PV array. This study focuses on two common types of algorithms of MPPT,“namely perturb and observe (P&O) and incremental conductance (INC)”. A DC-DC boost converter is implemented to regulate the voltage output from the PV array's and for the application of the MPPT algorithm.
