Implementation of Modified Perturb and Observe Based MPPT Algorithm for Photovoltaic System

The present paper treats with the implementation of the modified P&O (perturb and observe) maximum power point tracking (MPPT) algorithm to improve its performance. Firstly, the simulation study and comparison between the modified and the conventional P &O methods are presented to offer the efficacy of the developed method. Secondly, to verify the effectiveness of the developed method, practical validation is carried out using an Arduino Mega. The experimental and simulation tests present that the tracking speed is increased and fluctuations around the MPP (maximum power point) are reduced which demonstrates that the proposed algorithm overcomes the drawbacks of conventional one, and it does not require any extra hardware components.
