Comparative Review of MPPT Algorithms

The research on renewable energies was accelerated due to the speed-up of the global warming, caused by the accumulation of greenhouse gases (GHG) released largely by the burning of fossil fuels. Photovoltaic energy is environment friendly, however it can present adverse effects like electrical non-linearity. To mitigate such effects, the most efficient solution is the implementation of a maximum power point tracking algorithm (MPPT). The aim of this work is to carry out a review on the latest five years (2015 to 2020), regarding the conventional and novel methods of MPPT. In order to fulfill this objective a bibliographic research was carried out in the Scopus database. The analysis of the selected articles pointed out to 67 MPPT algorithms and show that although there are many algorithms being proposed today, yet still exists a lack of a deeper cost approach which lead to a reduction in the inverter’s final prices.
