Driven by this trend, comprehensive simulation tools are required to accurately analyze large-scale distribution systems with a fast-computational speed. In this paper, we propose an efficient method for performing time-series simulations for unbalanced power distribution systems with PV. Unlike the existing iterative methods, the proposed method is based on machine learning. Specifically, we propose a fast, reliable and accurate method for determining energy losses in distribution systems with PV. The proposed method is applied to a large-scale unbalanced distribution system (the IEEE 906 Bus European LV Test Feeder) with PV grid-connected units. The method is validated using OpenDSS software. The results demonstrate the high accuracy and computational performance of the proposed method.}, year = {2020}, journal = {International Journal of Interactive Multimedia and Artificial Intelligence}, volume = {6}, number = {4}, pages = {157-163}, month = {12/2020}, issn = {1989-1660}, url = {https://www.ijimai.org/journal/sites/default/files/2020-11/ijimai_6_4_17.pdf}, doi = {10.9781/ijimai.2020.08.002}, }
