Abstract: FACTS are the power electronic-based systems that provide fast and effective control of fundamental transmission characteristics like voltage, impedance, and phase angle. Hence allowing power networks to work in a far more efficient manner. The various FACTS devices directly integrated into gearbox lines improve power flow and system stability and include shunt and series compensators. One such device is the UPFC that provides full control capability by injecting the required voltage into the line through converter- based operation. Its dynamic responsiveness to voltage sags, swells, and harmonic disturbances is further refined through sophisticated control techniques such as neural- network-based modulation. The proposed approach to power quality improvement in a 230V distribution system is validated through simulation studies in MATLAB/Simulink and matching hardware implementation using renewable energy sources.
