2. ABSTRACT Dynamic voltage restorers (DVR) are complicated static devices which work by adding the ‘missing’ voltage during a voltage sag. Basically this means that the device injects voltage into the system in order to bring the voltage back up to the level required by the load. Injection of voltage is achieved by a switching system coupled with a transformer which is connected in series with the load.

3. LITERATURE SURVEY "Power quality improvement using novel dynamic voltage restorer based on power electronic transformer“ this paper discuss about the conventionally utilized in the electrical distribution system to mitigate the voltage sag and swell on point of common coupling of sensitive consumers. a novel DVR based on power electronic transformer (PET) is proposed to mitigate the symmetrical and asymmetrical voltage sag and voltage swell. "Mitigation voltage sag using DVR with power distribution networks for enhancing the power system quality“ this paper discuss about the The fast developments in power electronics technology have made it possible to mitigate voltage disturbances in power system. Among the voltage disturbances challenges in the industry, voltage sags are considered the most critical problem to sensitive loads.  "Review of FACTS technologies and applications for power quality in smart grids with renewable energy systems“ this paper discuss about the merging use of renewable and distributed energy sources in electricity grid has created new challenges for the utility regarding the power quality, voltage stabilization and efficient energy utilization.

4. "Impact of FACTS devices on transmission and distribution system“ this paper discuss about the devices are evolving technologies to mitigate voltage sags, swells, flickers and harmonics during transient and steady state operations. Power electronics and communication technologies have made the conventional grid smart and artificial intelligence based algorithms even smarter. "A novel facts based dynamic voltage compensation scheme for smart electric grid stabilization and efficient utilization“ this paper discuss about the modulated power filter compensator (MPFC) scheme for the smart grid stabilization and efficient utilization. The MPFC is controlled by a novel tri-loop dynamic error driven inter coupled modified PID controller. The Matlab digital simulation models of the proposed MPFC scheme has been fully validated for effective power quality.
