Overview
ISO/IEC 15067-3-3:2019 is an international standard developed by ISO and IEC that outlines a high-level architecture and set of models for demand-response energy management systems featuring multiple interacting Energy Management Agents (EMAs). Specifically designed for home electronic system (HES) environments, this standard supports implementations in single residences, multi-unit buildings, and broader residential communities, such as apartment complexes or campuses. The standard addresses the coordination of EMAs that may be structured in hierarchical, mesh, or hybrid topologies, enhancing flexibility, scalability, and efficiency in smart energy systems.
Key Topics
-
Energy Management Agents (EMAs): Defined as sets of control functions that automate energy allocation, EMAs can manage energy consumption for individual appliances, subsystems, or whole buildings. They enable intelligent switching between energy sources (e.g., grid, local generation, storage) based on consumer preferences and system requirements.
-
Interacting EMA Models: ISO/IEC 15067-3-3 describes two primary interaction designs:
- Hierarchical Model: Centralized server EMAs coordinate and allocate resources among client EMAs, optimizing energy usage and demand across larger domains.
- Mesh Model: EMAs cooperate as equals, autonomously negotiating energy use and sharing information to optimize control locally and community-wide.
-
System Topologies:
- Local EMA Topology: All EMAs are deployed within the home or residential community, managing different appliances or subsystems.
- Hybrid EMA Topology: Combines local EMAs with supplemental EMAs in the cloud, allowing for remote management, advanced analytics, and integration with utility signals via secure communication channels.
-
Demand-Response Support: The standard enables direct or indirect load control through utility or third-party provider interactions, demand optimization, real-time pricing, and incentive-based energy management.
Applications
ISO/IEC 15067-3-3 provides practical, strategic value in the following areas:
-
Smart Homes and Buildings: Supports implementation of advanced energy management, integrating local smart devices, distributed energy resources (DER), and cloud services to improve energy efficiency and reduce costs.
-
Community Energy Management: Enables optimization and sharing of energy resources between units or buildings within a residential community, facilitating demand balancing, local energy trading, and peer-to-peer energy sharing.
-
Utility Integration and Demand Response: Allows utilities or energy service providers to communicate energy pricing signals, event notifications, and demand-response requests securely, empowering end-users to participate automatically in grid management and incentive programs.
-
Fault Tolerance and Scalability: Multiple interacting EMAs improve system reliability, ensure maintenance can be localized, and support rapid, parallel expansion of energy management capabilities.
-
Consumer Empowerment: Enhanced user interfaces and automation help homeowners and building managers set preferences, manage budgets, and participate in energy markets with minimal manual intervention.
