Overview
ISO/IEC TR 15067-3-2:2016 - "Information technology - Home Electronic System (HES) application model - Part 3-2: GridWise - Interoperability context-setting framework" is a Technical Report that adapts work from the GridWise Architecture Council. It provides a high-level, context-setting interoperability framework intended to help identify, discuss and prioritize interoperability issues for entities that interact with electric power systems. The report is non‑normative guidance (state‑of‑the‑art) for aligning technical, informational and organizational concerns across the smart grid and building/ HES domains.
Key Topics
The report organizes interoperability into layered categories and cross‑cutting concerns to make integration issues tractable:
-
High-level categories (layers):
- Category 1: Basic Connectivity - physical and link connectivity fundamentals
- Category 2: Network Interoperability
- Category 3: Syntactic Interoperability - message formats and protocols
- Category 4: Semantic Understanding - shared meaning of data
- Category 5: Business Context - commercial and operational semantics
- Category 6: Business Procedures
- Category 7: Business Objectives
- Category 8: Economic and Regulatory Policy
-
Cross-cutting technical topics:
- Shared meaning and semantic mapping
- Resource identification and discovery
- Time synchronization and sequencing
- Security, privacy, logging and auditing
- Transaction and state management
- Quality of Service (QoS), system preservation, scalability and evolution
- Discovery, configuration and governance
-
Approach and intent: Provides vocabulary, viewpoints and example scenarios (e.g., residential and commercial demand response) to guide stakeholders through integration decisions and tradeoffs.
Applications and Who Uses It
This framework is practical for organizations and professionals involved in smart grid and HES integration, including:
- Utilities and bulk power system operators planning demand response and distributed energy resource (DER) integration
- Energy service providers and aggregators coordinating consumer-side automation
- Building automation and HES vendors designing devices and controllers that interoperate with grid signals
- System integrators, standards developers and policymakers aligning technical, commercial and regulatory requirements
- Security architects and operations teams addressing cross-cutting concerns like time sync, logging and privacy
Use cases include demand response orchestration, price‑based control of consumer equipment, DER coordination and multi‑stakeholder systems integration.
Related Standards
- Part of the ISO/IEC TR 15067 HES application model series and developed under ISO/IEC JTC1 collaboration.
- Complements domain standards and smart‑grid interoperability efforts (GridWise Architecture Council work) by offering a context-setting taxonomy and governance considerations.
