DIGITALIZATION OF HV SUBSTATIONS -IDS INTRUSION DETECTION SYSTEMS

High-voltage (HV) substations represent key elements of the transmission part of the power system, enabling the connection of energy sources with significant installed capacities to a diverse range of electricity consumers. The energy transition, driven by global decarbonization initiatives and climate actions such as the Paris Agreement and Net Zero goals, has significantly influenced changes in power systems. Digitalization through the IEC 61850 standard offers concrete solutions to these challenges, with a particular focus on enhancing communication aspects. The implementation of sophisticated communication systems, based on modern digital devices and cybersecurity principles, is an extremely complex and dynamic process. Successful implementation requires precise planning, as well as compliance with relevant standards to ensure the stability, reliability, and security of modern power systems. The application of modern technologies, such as Intrusion Detection Systems (IDS), enables proactive monitoring of network traffic and real-time anomaly detection. This paper presents an analysis of cybersecurity in HV substations based on the guidelines of NIST CSF 2.0 – National Institute of Standards and Technology Cybersecurity Framework Version 2.0.
