In the last 40 years, power quality has become a key problem for both distribution and transmission systems. The system has many flaws, such voltage sag. The advantages of the multi-level inverter (MLI) in extremely high voltage and high power applications with minimal harmonics have drawn a lot of attention in recent years. This project describes how to create the Dynamic Power Restorer system, which uses a microprocessor to operate a multilayer inverter to counteract voltage sags. In order to shield sensitive electronics from line failures like voltage sag, this project designs a MATLAB simulation of a multi-stage and multi-level dynamic voltage restorer system. This project uses a novel multilayer inverter architecture that produces a seven-level inverter waveform. This project uses a voltage reading circuit to continuously check the input line voltage. One stage of a multi-level inverter will inject voltage into the line if the system's voltage exceeds than 190 volts, and both levels will inject voltage into the system if the level is less than 170 volts. The analysis of electric vehicle efficiency in many electrical elements is covered in this essay, along with the difficulties and benefits of using them as a logical step toward efficient, environmentally friendly, and sustainable system.
