Comparative Analysis of MPPT Techniques for Boost Converter Control in Solar Photovoltaic System

These days, it's rather usual to employ MPPT (Maximum power Point Tracking) approaches to get the most electricity possible out of a solar panel. The paper presents four techniques employing MPPT, i.e. P&O (Perturb & Observe), InC (Incremental Conductance), Hill Climb and Modified P&O technique. The boost converter along with all four MPPT techniques are described and simulated for comparative analysis based on output power of PV panel, ripples, settling time, overshoot and undershoot. The simulation results conclude that among all the for MPPT techniques discussed the Hill Climb technique reduces the ripples and overshoots but can’t extract maximum power so the best is Modified P&O technique because it utilizes the solar panel to get maximum power with less ripples.
