This part of ISO/IEC 15067 specifies a high-level architecture and a set of models for a demand-response energy management system with multiple interacting EMAs in a home or community housing (such as one or more apartment buildings or a campus of houses). These models specify the structure among multiple EMAs, which can be arranged in a mesh or hierarchical structure. This document builds upon ISO/IEC 15067-3.dition 1.0 2019-10 INTERNATIONAL STANDARD colour inside Information technology – Home electronic system (HES) application model – Part 3-3: Model of a system of interacting energy management agents (EMAs) for demand-response energy management ISO/IEC 15067-3-3:2019-10(en) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2019 ISO/IEC, Geneva, Switzerland All rights reserved.
