Power Quality Enhancement in Renewable Energy-Based Distributed Generation Using DPFC

This paper presents an advanced approach for improving power quality in renewable energy-based distributed generation (DG) systems by integrating a Distributed Power Flow Controller (DPFC). The proposed hybrid system, combining solar and wind sources, faces challenges like voltage sags, current swells, and harmonic distortion. A DPFC is introduced to mitigate these disturbances. The simulation, performed using MATLAB/Simulink, demonstrates the system's ability to stabilize voltage, regulate current, and reduce Total Harmonic Distortion (THD). The results highlight the effectiveness of DPFC in enhancing system reliability, making it suitable for smart grid applications.
