چکیده
-Dynamic Voltage Restorer (DVR) is a device used to mitigate voltage sags which are a significant power quality issue. This paper involves mathematical calculation for leading series voltage injection for mitigation of sags thereby achieving utility power factor improvement as well as power sharing between DVR and utility as per requirement and available distributed generation. Mathematical derivations have been made for leading voltage injection and simulation results verifying these calculations have been included.
