Abstract
Increased penetration levels of Distributed Generation (DG) can cause harmful harmonics and power quality issues for the power distribution system. This project aims to investigate harmonic and power quality issues related to high penetration levels of DG. The existing harmonic and power quality concerns and problems caused by DG on typical power distribution systems will be studied. The focus will be on a commonly used type of DG known as solar Photo-Voltaic (PV) that contributes to power quality issues. Sample tests utilizing a case study of power quality at a PV plant in Princeton, NJ, and simulation results showing the power quality problems will be analyzed. Possible solutions and recommendations for mitigating these power quality issues will be investigated.
