ANFIS control of a shunt active filter based with a five-level NPC inverter to improve power quality

This paper addresses the problem of power quality, and degradation current waveform in distribution network which results directly from proliferation nonlinear loads. We propose to use a five-level neutral point clamped (NPC) inverter topology for implementation shunt active filter (SAPF). The aim SAPF is inject harmonic currents phase opposition at connection point. identification harmonics based on pq method. A neuro-fuzzy controller ANFIS (adaptive neuro fuzzy inference system) designed SAPF. simulation study carried out using MATLAB/Simulink show significant improvement quality energy reduction total distortion (THD) accordance with IEC standard, IEEE-519, 61000, EN 50160.
