Modeling a photovoltaic panel with the algorithm incremental conductance to maximize efficiency using matlab/simulink ® Software

Abstract

A photovoltaic cell junction forms a photovoltaic panel that has small efficiency, occasioning a maximum power unavailability. The maximum power depends on temperature and irradiation’s environmental conditions. To provide maximum power, it is recommended to add an electronic system known as maximum follower. The Maximum Power Tracker, also known as MPPT (Maximum Power Point Tracking), alters the operation of the converter connected to the photovoltaic panel array, thereby allowing maximum power availability regardless of irradiation and temperature values. Some MPPT algorithms are used to allow the optimization of solar energy. As a result of the maximum power efficiency, the MPPT Conductance Incremental algorithm was used. Through the software MatLab/Simulink ®, the modeling and simulation of the photovoltaic panel was carried out. The output current and the power of the photovoltaic panel depends on the Irradiation. The Incremental Conductance algorithm was efficient, given that the results obtained with this algorithm compared to the output power values of the photovoltaic panel presented relative errors lower than 10%.
