Grid-connected photovoltaic (PV) systems are increasingly attracting the attention of industry andacademia as a means of providing an alternative to conventional fossil-fuel generation and pollution-freepower. This project aims to improve the power quality level of a grid-tied PV distribution system using shuntactive power filter (APF) along with adaptive current control technique.In this work Fuzzy Logic controller used to destroy the voltage and current harmonics in a grid-tied PVsystem. A reference current generation strategy is implemented to mitigate the current harmonics byextracting the fundamental constituents (FCs) from the nonlinear load currents. MCCF is employed toseparate the FC from the distorted grid voltages and eliminates the voltage harmonics during extremelypolluted grid voltage condition. The comparative analysis is analyzed to check the effectiveness of theproposed hybrid control scheme with existing and adaptive control techniques in respect of power quality,better dc offset rejection, better FC and frequency extraction, and grid synchronization.
