Study on the effect of Distributed Generation towards unified power quality conditioner performance in mitigating voltage sags

The purpose of this paper is to study on the effects of Distributed Generation (DG) towards unified power quality conditioner (UPQC) performance in mitigating voltage sags. The interest in DG has been increasing rapidly because DG might play an important role in the future power system. This paper will focus on the analysis of the comparison in the distribution system before and after the occurrence of mitigating voltage sags based on different type of phase to ground fault. This paper also will focus on the analysis of the effectiveness and efficiency in mitigating the voltage sags. The type of faults is analyzed using PSCAD simulation to observe the effectiveness and efficiency of the UPQC. Throughout this simulation, voltage sags problem can be solved and mitigated to decrease losses.
