An Accurate ANFIS-based MPPT for Solar PV System

It has been found from the literature review that the ANFIS-based maximum power point tracking (MPPT) techniques are very fast and accurate in tracking the MPP at any weather conditions, and they have smaller power losses if trained well. Unfortunately, this is true in simulation, but in practice they do not work very well because they do not take aging of solar cells as well as the effect of dust and shading into account. In other words, the solar irradiance measured by solar irradiance sensor is not always the same irradiance that influences the PV module. The main objective of this work is to design and practically implement an MPPT system for solar PV with high speed, high efficiency, and relatively easy implementation in order to improve the efficiency of solar energy conversion. This MPPT system is based on ANFIS technique. The contribution of this research is eliminating the need of irradiance sensor while having the same adequate performance obtained by the ANFIS with irradiance sensor, both, in simulation as well as in experimental implementation. The proposed technique has been validated by comparing the practical results of the implemented setup to simulations. Experimental results have showed good agreement with
