Real-time implementation of the MPPT algorithm based on fuzzy logic for solar PV system

Abstract

This paper presents an intelligent approach based on the fuzzy logic concept, to optimally find out the maximum power point (MPP) to extract maximum power from a photovoltaic (PV) array. The fuzzy logic-based MPP tracking (MPPT) is tested and analyzed through MATLAB/Simulink and hardware-based PV modules. To justify the feasibility of realtime application of the approach, a hardware setup is built using Arduino mega 2560 embedded board, MinGW-w64 simulator, and Simulink support package for Arduino Hardware in MATLAB/Simulink 2020. To execute the real-time conditions, both the temperature (T) and irradiance (G) variations are considered in different test cases. The results indicate the high efficacy and feasibility of the approach for real-time application.
