Plug-In Software for the Phase Distribution of Single-Phase Consumers in Electric Grids Used in Digital Twin Design and Development Based on the BIM Technology

This article presents a solution algorithm for single-phase power consumer distribution. It stipulates calculating the best distribution of power consumers across the phases of lines L1, L2, L3 using the minimization of the load unbalance impact on the losses in power grid elements used for the electric power transfer. To solve this problem, the authors employed the complete enumeration method implemented with a tertiary numerical system used to code power consumer distribution across the power supply grid phases. The coefficient accounting for the unbalance of load distribution across power grid phases is used as the target function. The developed algorithm can be applied as an external plug-in for the Revit software package by Autodesk to distribute the power consumers of one of the rooms in a BIM office building. The developed algorithm is compared to the existing widely-used approaches to single-phase power consumer distribution in power grids. The developed algorithm allowed producing brand-new engineering solutions while developing a design document for the power supply grid (design and detailed documentation stage). They help improve the efficiency of electric power transmission by reducing additional losses caused by unbalanced loads.
