Comparison Study between conventional and advanced MPPT based on fuzzy logic and ANFIS for standalone system

This paper provides a comparative Study between conventional P&O and advanced Maximum power point tracking (MPPT) algorithms based on fuzzy logic control (FLC) and Adaptive Neuro-Fuzzy Inference System (ANFIS) for standalone application. In order to achieve the operating point, the proposed MPPT techniques control the duty cycle of a DCDC converter which interfaces the load and the PV generator. The conventional P&O algorithm is discussed due to its simplicity and low implementation cost but its dynamic behavior is considered worst especially in rapid irradiation changes. Hence, FLC and ANFIS are supposed to perform better in term of power ripples elimination and the tracking accuracy. However, simulation results have been recorded by using Matlab/Simulink. These results prove the privilege of the advanced techniques over conventional algorithm.
