Summary
The increasing deployment of IoT-based (Internet of Things) sensors in power systems introduces significant integration challenges due to incompatibilities between modern communication protocols and existing SCADA (Supervisory Control and Data Acquisition) infrastructures. This paper presents an open-source, universal substation gateway designed to bridge this gap through a modular, microservice-based architecture.

A central real-time database (RTDB) serves as a unified source of normalized data, managing timestamps, data quality, redundancy, and publish/subscribe mechanisms optimized for edge computing environments. Unlike traditional tag-based SCADA approaches, the solution adopts an object-oriented data model aligned with the CIM (Common Information Model) standard, ensuring consistent identification and semantic interoperability across systems. The architecture supports real-time data aggregation, calculated parameters, historical data archiving, and redundant communication paths for high availability.
The proposed approach provides a scalable, protocol-agnostic platform that enables utilities to integrate new sensor technologies while preserving compatibility with legacy SCADA systems, supporting grid digitalisation and operational efficiency.
