The increased use of nonlinear loads in distribution system leads to distortion in voltage & current waveforms and injecting harmonics and thus the system inherently gets unbalanced. Harmonics generation becomes a grave concern in distribution system. Besides this, the voltage sag-swells and power factor also create the power quality problem at the utility side. Hence, reduction of these power quality issues in the system is important. There are other issues during installation of distributed generation, which must be evaluated and mitigated for the better performance of the system. The usage of power enhancement device such as unified power quality conditioner (UPQC) can simultaneously fulfil different objectives, such as maintaining a sinusoidal voltage at the point of Installation. The UPQC which has two filters (series and shunt active power filters) are to be placed in a distorted distribution line to provide the system sinusoidal current. This project proposes the placement of Unified Power Quality Conditioner (UPQC) for the power quality improvement and is to be tested in 33 bus radial distributed system.
