Modeling and analysis of simplified PV module with various temperature and irradiance inputs using MATLAB simulink algorithm

Abstract

Photovoltaic (PV) systems offer a potential solution to the global energy crisis. Modeling study and analysis involving solar PV module is an important task in a PV system to be more user friendly, improve reliability and performance. However, the output characteristics of PV modules are nonlinear, since they are dependent on environmental conditions such as solar irradiance and temperature, as well as local climate conditions such as humidity and wind. The various methods used have some common gaps as the absence of step-by-step procedure which causes difficulties to understand. Indeed, accurate modeling of PV modules is important to provide a better understanding of their operation and output characteristics, since simulations can be used to understand the behavior of PV modules under various operating conditions. The objective of the project is first, to build and model a solar photovoltaic (PV) module algorithm using Matlab/Simulink. Second, to simulate and analyze the behavior of the model in various temperature and irradiance input conditions. Third, to validate the results obtained from the simulations by comparing the output characteristics with the manufacturer’s datasheet. The methodology used by presenting the principles of detailed modeling of PV modules using Matlab/Simulink software. The constructed model is taken from the equations obtained from the equivalent circuit of a single diode model. The PV Module block is a five-parameter model using a light-generated current source (IL), diode, series resistance (Rs), and shunt resistance (Rsh) to represent the irradiance and temperature-dependent I-V and P-V characteristics of the module. This method provides a simple, reliable, and highly flexible method to adapt PV modules to different environmental conditions such as irradiance, temperature and physical parameters of the solar modules such as resistance, current, voltage, ideality factors and others. The simulation results and data obtained show that the block module developed and simulated using Matlab/Simulink with various input values ​​of temperature and irradiance is almost identical to the real PV module and user-friendly.
