Abstract :The Increasing Penetration Of Renewable Energy Sources Into The Power Grid, Maintaining Power Quality Has Become A Significant Concern. Voltage Source Inverters (VSIs), Commonly Used For Interfacing Renewable Energy Systems Like Solar PV And Fuel Cells, Must Not Only Inject Active Power But Also Mitigate Power Quality Issues Such As Harmonics, Unbalanced Loads, And Reactive Power Demands This Paper Presents The Design And Control Strategy For A Grid-connected Dual Voltage Source Inverter (Dual VSI) Aimed At Enhancing Power Quality In Distributed Generation (DG) Systems. The System Utilizes Two Interlinked VSIs Operating In Coordination To Manage Both Active/reactive Power Flow And Mitigate Power Quality Issues Such As Harmonic Distortion, Voltage Sag, And Unbalanced Loads. A Synchronized Control Algorithm Based On Decoupled D-q Reference Frame Theory And A Novel Feedforward Compensation Mechanism Is Employed To Improve Dynamic Response And Reduce Total Harmonic Distortion (THD). Simulation Results In MATLAB/Simulink And Experimental Validations Confirm The Effectiveness Of The Proposed Dual VSI Configuration In Achieving Superior Power Quality Compared To Conventional Single VSI Setups.
