An Intelligent Maximum Power Point Using a Fuzzy Log Controller under Severe Weather Conditions

Abstract EN

This study is aimed at providing a comparison between fuzzy systems and convectional P&O for tracking MPP of a PV system.

MATLAB/Simulink is used to investigate the response of both algorithms.

Several weather conditions are simulated: (i) uniform irradiation, (ii) sudden changing, and (iii) partial shading.

Under partial shading on a PV panel, multipeaks appeared in P-V characteristics of the panel.

Simulation results showed that a fuzzy controller effectively finds MPP for all weather condition scenarios.

Furthermore, simulation results obtained from the FLC are compared with those obtained from the P&O controller.

The comparison shows that the fuzzy logic controller exhibits a much better behavior.
