A Low-Cost Maximum Power Point Tracking Method Based on PI Controller Arduino Implementing

This paper aims to present a method to improve the conventional perturb and observe (P&O) maximum power point tracking (MPPT) algorithm for buck converters, which is based on a proportional-integral (PI) controller to solve the main P&O MPPT drawback, which is the presence of the ripples in the output power of the converter. Currently, many electronic devices (FPGA, dSPACE...) are used to implement the MPPT methods, but they remain relatively expensive. For this reason, the Arduino board is used in this work to implement the suggested MPPT algorithm. To validate its function, a comparative study between the proposed P&O algorithm and the conventional one is developed in MathWorks software, and an experimental setup using hardware components is given at the end of the paper.
