Abstract :
The dynamic voltage restorer (DVR) is an effective solution for power quality problems related to the voltage. In this paper, a multi-functional DVR presented that in addition to compensating voltage sag and voltage swell can limit fault current and keep constant large variation of the system frequency. In this multi-functional DVR the minimum energy theory for reducing active power that consuming or absorbing is considered. The simulation results obtained by PSCAD/EMTDC to verify the effectiveness of the multi-functional DVR and its control strategy for power quality improvement.
