Intelligenit MPPT algorithm for PV system based on fuzzy logic

摘要

This paper deals with an analysis of a control method proposed for tracking the maximum power point (MPPT) generated by photovoltaic systems. The proposed algorithm, fuzzy logic control (FLC), is developed and implemented in Matlab/Simulink environment to command the Photovoltaic array (PV) via the dc-dc converter that are modeled. To approve the efficiency of the control algorithm, many simulations have been done considering the different system responses as the current, voltage and essentially the power. The results of the FLC algorithm shown that the perfect efficiency is achieved when the optimum duty cycle is generated.
