      abstract = {As the LV distribution feeder continues to experience increasing and uneven integration of single-phase rooftop PV systems with variations in per-phase load, the distribution feeder will face increased system losses, excessive heat in customers' equipment resulting in accelerated ageing or component failure, and transformer failure due to high voltage unbalance. In this paper, a radial LV distribution is modeled in MATLAB/Simulink environment to investigate the effect of uneven distribution of a single-phase PV array on voltage imbalance. The investigation covered three different scenarios (PV array distribution pattern). IEEE Standard 45-2002 definition of voltage unbalance was used to evaluate the percentage voltage unbalance of the feeder. According to the simulation results, the percentage voltage unbalance for scenarios 1, 2, and 3 is 9.87%, 7.68%, and 5.93%, respectively, and are higher than the 3% voltage unbalance limit specified in IEEE Standard 45-2002. These voltage unbalance levels are harmful the system loads, motors and transformers. Therefore, proper regulation of the single-phase PV arrays is required so as to control the voltage unbalance level in LV distribution feeder.},
