Overview
ISO/IEC 15067-3:2012 - Information technology - Home electronic system (HES) application model - Part 3: Model of a demand-response energy management system for HES - defines a high-level energy management model for managing consumer electricity demand using demand response (DR) methods. This international standard updates the 2000 technical report, expands DR options, incorporates distributed energy resources (DER) such as local generation and storage, and aligns DR terminology with the smart grid ecosystem.
Key topics and technical scope
- Demand response methods: Specifies three DR types - direct control, local control, and distributed control - and explains how each affects appliance behavior and grid interactions.
- Energy management model: Presents a generic HES model covering components, information flows and communications services needed for DR-based energy management.
- Distributed control architecture: Defines roles for smart appliances, local controllers, and system agents to enable automated or price-driven load adjustments.
- Energy Management Agent (EMA): Introduces the EMA concept for coordinating grid-to-home and home-to-grid functions, including price-to-device mechanisms and event notification.
- Taxonomy, use cases and lexicon: Provides a structured taxonomy, multiple use cases (local, direct, supervised direct, distributed, advanced distributed, intelligent-appliance control, utility telemetry) and a message lexicon for HES energy management communications.
- Inclusion of DER and storage: Addresses integration of local generation (e.g., PV) and storage into demand response strategies.
- Conformance and interoperability: Focuses on interoperable communications and services for HES devices to support smart grid objectives.
- Supporting material: Informative annexes on premises equipment, demand-side management and value-added services.
Practical applications
- Design and implementation of home energy management systems (HEMS) and smart appliances that respond to utility signals or local conditions.
- Development of utility DR programs, tariffs and event-notification systems that interact with customer premises equipment.
- Integration of distributed generation and storage into residential energy control strategies.
- Creation of interoperability profiles, middleware and APIs for home electronic systems (HES) and smart-grid gateways.
- Use by aggregators, energy service companies (ESCOs) and smart-home platform developers to build compliant DR services.
Who should use this standard
- Utilities and grid operators designing residential DR programs
- Appliance and smart-device manufacturers targeting HES interoperability
- Homebuilders, building automation integrators and system architects
- Third-party DR aggregators, ESCOs and software developers
- Standards bodies and test labs working on smart-grid/HES conformance
