Comparison of two MPPT methods fuzzy logic and ripple correlation control for the application of LED lighting supplied by photovoltaic panels grid

Abstract

This article compares the efficiency of two methods, fuzzy logic and ripple correlation control to track the maximum power point of a photovoltaic panel used for LED lighting supply in order to illuminate locals which need artificial light during the day. The use of this technique will reduce power consumed through the electrical grid and consequently decrease the rate of carbon dioxide. Calculation examples shown in this paper are based on Moroccan CO2 emission factor for electricity and they have illustrated that a large quantity of CO2 will be avoided. The simulation results have shown the effectiveness of fuzzy logic (Mamdani model) for tracking the maximum power point. The connection with the electrical network upon an irradiation below 680 W/m2 is used.
