Guidelines for high penetration of single-phase PV on power distribution systems

A study was performed to determine the impact of single-phase photovoltaic (PV) generation on distribution laterals at high penetration levels. The study addresses concerns about the impact on load balance, fault current balance, power quality and islanding conditions. Methods and tools used for this study, which are appropriate for general analysis of PV on single-phase laterals, are discussed. Guidelines for the acceptance of single-phase PV connections without detailed study also are presented.
