The paper presents the method of harmonic attenuation with better dynamic response in the three-phase grid-connected photovoltaic system by using Maximum Power Point Tracking (MPPT) voltage regulator with varied increment. Since electrical power of PV array depends on the climatic condition. Maximum Power Point Trackers are used to extract maximum energy from photovoltaic generators. In this paper, every time the amount of electrical power generated by solar arrays changes continuously with

The simulation results in Simulink/Matlab show that the proposed MPPT voltage regulator with varied increment is better than with fixed.
