Overview - IEC TR 62357-200:2015 (IPv4 → IPv6 migration for power systems)

IEC TR 62357-200:2015 provides guidelines for migrating power systems communications from Internet Protocol version 4 (IPv4) to Internet Protocol version 6 (IPv6). The Technical Report focuses on information exchange across power-system domains - substations, control and maintenance centres, energy management, synchrophasor systems, bulk and distributed generation (renewables), energy storage and load management. It describes migration strategies, impacts on applications and the communication stack, and necessary migration paths for IEC 61850-related protocols while considering backward compatibility.

Key technical topics and requirements

• Migration strategies and planning
  • Types of migration (dual-stack, tunneling, translation) and a recommended migration plan.
  • Timetable and procedural considerations for staged implementation.
• Addressing and configuration
  • IPv6 addressing models, IPv4/IPv6 mapping and address allocation considerations for power systems.
  • Impact on IEC 61850 addressing and representation.
• Stack and node impact
  • Effects on application layers, communication stacks, network nodes and device configuration.
  • Dual-stack device architectures and deployment patterns (including Bump-in-the-Host).
• Tunneling and translation techniques
  • Standard tunneling protocols and methods to carry IPv4 over IPv6 and vice versa.
  • Translator and Application-Level Gateway (ALG) implications for utility protocols.
• Security and management
  • Cyber security considerations and management requirements during migration.
  • Recommendations for secure transition paths and operational continuity.
• Practical scenarios and use cases
  • Substation automation scenarios, integration of IPv6-only devices into IPv4 networks, and a generation-plant migration use case.

Practical applications - who uses this standard

• Utility network engineers and architects - plan and execute IPv6 rollouts across substations and control centres.
• Device and IEC 61850 equipment manufacturers - implement IPv6-ready firmware, addressing schemes and dual-stack support.
• System integrators and consultants - design migration strategies, tunneling/translation solutions and interoperability testing.
• Cybersecurity teams - assess risks introduced by migration methods and define secure management practices.
• Standards bodies and project managers - harmonize IEC 61850 protocol evolution and backward compatibility with IPv6.
