Title:A Modified Fuzzy Logic Controller Based Maximum Power Point Tracking under Partial Shading
Author Name:A. Narendra and M. Sai Veerraju
Synopsis:
Under partial shading conditions, multiple peaks are observed in the power-voltage (P-V) characteristics curve of a photovoltaic (PV) array, and conventional maximum power point tracking (MPPT) algorithm may fail to track the global maximum power point (GMPP). In this paper a fuzzy-logic controller for global maximum power point tracking (GMPPT) is proposed to increase the performance during partial shading condition. A mathematical model of the PV system under partial shading conditions is derived. The proposed fuzzy logic based controller is implemented in MATLAB- SIMULINK.
