Hardware implementation of improved perturb and observe maximum power point tracking technique for photovoltaic systems with zero oscillations

This paper presents a Maximum Power Point Tracking (MPPT) method for a solar photovoltaic system utilizing the k factor approach and performance parameters. This method for MPPT execution is created by calculating the slope (dI/dD) and comparing it with the power change($\Delta$P). The duty cycle($\Delta$D) is calculated by analyzing the power change. And this power change makes the MPPT method to reach the maximum power point faster with less fluctuations using the constant k with value 0.8. In MATLAB/Simulink, the proposed technique is implemented and compared with the Perturb Observe and Incremental conductance technique, the findings indicate a decrease in monitoring time and steady-state power oscillations.
