Power Factor Improvement in Vienna Rectifier Based Grid Tied Wind Energy Conversion System Using (ANFIS and FLC) Controllers by Reducing Total Harmonic Distortion

This paper presents the comparative analysis on power factor in Vienna rectifier based grid tied wind energy conversion system using ANFIS (Adaptive Neuro Fuzzy Inference System) and FLC (Fuzzy Logic Control) controllers. ANFIS and FLC controllers are implemented to analyse the power factor of grid tied wind energy conversion system (WECS) under a constant wind speed of 12 m/s. Sample size is calculated using Gpower and has 20 samples totally: Based on the obtained result, it is inferred that ANFIS controller (0.8110) than based WECS has better power factor when compared to FLC (0.6530) based WECS. Vienna rectifier based grid tied wind energy conversion system using ANFIS controller gives better power factor when compared to FLC controller.
