Implementation of fractional open circuit voltage mppt algorithm in a low cost microcontroller

Abstract

The solar or the Photovoltaic (PV) cell is a source of electric energy which is eco-friendly, free and though it is a renewable source of energy, it is relatively costlier and inefficient nowadays which includes the difficulties related to complete harnessing of solar power. The MPPT or the maximum power point tracking of the PV panel for every type of environmental and climatic circumstances is the vital strategy to get the maximum power output thus increasing the efficiency of solar power extraction mechanism. This project recommends an innovative and a more efficient method for the maximum power point tracking of photovoltaic systems that is the Fractional Open Circuit (FOC) Algorithm which estimates the MPPT by manipulating the Open Circuit voltage of the Photovoltaic Cell. The method considerably improves the tracking speed and accuracy of the maximum power point tracking when we relate the results with other techniques. This project gives a detailed analysis and report of the maximum power point tracking using the FOC voltage technique.
