A Fuzzy Logic MPPT For Three-Phase Grid-Connected PV Inverter

摘要

This paper suggests an innovative method to control a grid tied PV system and ensure the pursuit tracking the maximum power point (MPPT) under varying irradiance condition. This method applies a fuzzy logic controller (FLC) at DC/DC stage. The various stages of the conception of this method are introduced and computed. The outcomes of this simulation are compared with those acquired by conventional technique which is incremental conductance IncCo. The simulation demonstrated the utility and advantage of FLC over conventional method in term of speed and precision.
