A Review on Dynamic Voltage Restorer (DVR) to Improve Power Quality

In distribution system the most common phenomena is voltage sag, in which will be effected on the different load mostly sensitive. Generally the custom power devices is An effective solution to mitigate The DVR is a powerful controller that is commonly used for voltage sags. It use with the four different compensation method to eliminate the voltage sag and reduce the voltage disturbance at load side. The paper provide a review on the DVR and discussion on four compensation method and different control Strategy
