Implementation of a 2D/3D WebGIS for Electricity Network Management System

Abstract. Effective planning, management, and optimization of electrical distribution networks are essential components of modern smart city development and energy sustainability. This study presents a geospatial decision-support system for the low and medium voltage (LV/MV) network of Elektrokrajina d.o.o., the main electricity distributor in Republika Srpska. Model of the system is built upon the extended INSPIRE Utility Network – Electricity model. It leverages a 2D/3D WebGIS platform (ELMAP) to visualize, analyze, and manage electrical infrastructure using open-source technologies such as PostgreSQL/PostGIS, pgRouting, Geoserver and Mapbox. The integration of real-time and semi-structured data from sensors and enterprise systems (e.g., SAP, MDM) is enabled via service-oriented architecture and parallelized query execution. Particular attention is given to addressing topological inconsistencies in legacy data, reconstructing network topology, and linking meter positions to buildings using GPS and OSM data. Custom algorithms were developed for voltage-level tracking, meter reading route optimization, and network loss analysis, including indicators such as SAIFI, SAIDI, and peak loads. The platform enables spatial identification of critical infrastructure points and supports strategic decisions regarding transformer zoning, network upgrades, and demand management. This research highlights the importance of structured 3D geospatial data and demonstrates how scalable, open-source WebGIS systems can support the energy sector in meeting smart grid and sustainability goals.
