Abstract: The major power quality issue is voltage sag & swell that can cause mal- operation of sensitive electronic equipment. The power system is a complex network of generation, transmission, and distribution entities. With the increasing integration of alternating energy sources like wind-solar power, grid stability and power quality have become significant concerns. This research work suggest a technique like voltage sag control through desired power devices known as Dynamic Voltage Restorer (DVR) and STATCOM. A modified control system with compact switching devices and improved compensating capability is presented. The proposed technique utilizes voltage injection and pulse width modulation (PWM) signal control to mitigate sag/swell disturbances. The designed system results reflect the effectiveness of the desired mitigation methods or technique under various conditions. This project focuses on modeling and analyzing a DVR with a PWM-based controller using simulink, Highlight the most efficient control techniques for improving the power quality.
