Abstract
Distributed generation (DG) has substantially increased around the world and represents an important means of developing renewable energy power generation. The current levels of DG penetration in the Brazilian distribution networks do not cause any significant impact on medium-voltage grids. However, the low-voltage (LV) networks could face negative impacts, especially on voltage. Therefore, this study presents how advanced metering infrastructure (AMI) data could improve DG impact studies in LV distribution networks. The results obtained using AMI data were compared with the traditional methods used in distribution for load allocation. The distribution feeder and the AMI information were obtained from the Smart City Búzios project, implemented in Búzios, in the state of Rio de Janeiro, Brazil. The analysis on voltage was performed using the OpenDSS software. The results show that the traditional load allocation techniques could overlook excessive voltage rise. Therefore, AMI could provide important data to perform DG impact studies on LV distribution networks.
