Power quality is a crucial problem in today's electrical system that may affect both utilities and customers. The combination of smart grid technologies, power electronics technology, and renewable energy sources resulted in a number of problems with the present electric power system. Voltage sag, swell, and current and voltage harmonics may all cause damage to sensitive equipment. These parts are susceptible to input voltage variations caused by interference from other parts of the system. Because more and more costly and sophisticated electronic equipment is being used in modern times, power quality is essential to the power system's ability to operate safely and dependably. The Dynamic Voltage Restorer (DVR) is a prospective Distribution Flexible AC Transmission System (D-FACTS) device that is often used to handle problems with non-standard voltage, current, or frequency in the distribution grid. By introducing voltages into the distribution line to maintain the voltage profile, it guarantees a constant load voltage. The effectiveness of the DVR-based recommended approach for smoothing harmonically-distorted voltage was shown using MATLAB/Simulink simulations. A power system model with a changeable power source is used to add the third and fifth harmonics. When assessing how sensitive the systems are to load voltage, both situations with and without DVR are taken into account. The proposed DVR-based method has been seen to effectively manage the voltage distortion, resulting in a smoothly adjusted load voltage. When the supply voltage's third and fifth harmonics were added, the load voltage THD percentage was around 18% and 23%, respectively. The inclusion of the recommended DVR has reduced THD by less than 4% in both cases.
