Information technology - Home Electronic System (HES) application model - Part 3-30: Energy management agent functional requirements and interfaces

This document specifies functional requirements and reference interfaces for interconnected energy management agents (EMAs) based on the model for an EMA specified in ISO/IEC 15067-3 and the model for multiple interacting EMAs specified in ISO/IEC 15067-3-3. This specification supports energy management by facilitating interactions and information exchange among EMAs and appliances, consumer electronics, heating, ventilation, and air conditioning (HVAC) equipment, water heaters, distributed energy resources (DERs), electric vehicle (EV) chargers, and other loads supplied by public and local power sources in a house or an apartment complex. Local power sources can use DER, which can include, but are not limited to, wind turbines, solar panels, and storage (stationary and mobile). EMAs specified with these functions and interfaces can assist the consumer in responding to price-varying public power and buying or selling transactive energy (TE). This document specifies framework methods for EMAs to co-ordinate the delivery of energy management applications, and the reference interfaces facilitate a communications protocol among interacting EMAs. These linked and interacting EMAs provide energy optimization and conservation within constraints such as a consumer's financial budget and goals for greenhouse gas reduction, while supporting programmes as diverse as TE and demand response (DR).

Overview

ISO/IEC 15067-3-30:2024 defines functional requirements and reference interfaces for Energy Management Agents (EMAs) within the Home Electronic System (HES) application model. It specifies how multiple interconnected EMAs-deployed in a house, apartment complex or residential community-exchange information and coordinate energy management across appliances, HVAC, water heaters, EV chargers, distributed energy resources (DERs) and public/local power sources. The standard supports use cases such as dynamic pricing response, transactive energy (TE) and demand response (DR) while respecting consumer constraints like budgets and greenhouse‑gas reduction goals.

Key topics and technical requirements

• EMA functional requirements: High‑level responsibilities for EMAs to communicate, optimize and coordinate energy use and generation (see Clause 6).
• Reference interfaces: A four‑interface model is defined (southbound, northbound, eastbound, westbound) to facilitate protocol design and interoperability among EMAs and devices.
• Configuration models: Support for hierarchical and distributed EMA configurations for single homes, apartments, buildings and communities (Clause 5).
• Interoperability scope: Interfaces and information exchanges cover appliances, consumer electronics, HVAC equipment, EV chargers, DER (solar, wind, storage), and other loads.
• Operational goals: Enable energy optimization, conservation and coordination to meet constraints such as cost limits and greenhouse‑gas reduction targets.
• Conformance requirements: Implementations must follow the EMA configuration options in Clause 5 and the functional requirements and interfaces in Clause 6.

Practical applications

• Coordinating EV charging schedules to match low‑price periods or local DER output.
• Managing solar + battery systems to prioritize self‑consumption or sell TE back to the grid.
• Orchestrating HVAC and water heaters for demand response events while honoring occupant comfort and budgets.
• Enabling apartment building or campus‑level energy optimization through hierarchical or distributed EMA deployments.
• Supporting utilities and aggregators for transactive energy and programmatic DR integration.

Who should use this standard

• Smart‑home and HES product designers and integrators
• Energy management system developers and platform vendors
• DER and storage system manufacturers
• EV charger and HVAC OEMs implementing smart control interfaces
• Utilities, aggregators and building managers designing TE/DR solutions
• Standards and interoperability test labs

INTRODUCTION
This document specifies energy management agent (EMA) functional requirements and
interfaces for interconnected energy management agents in a house, an apartment complex, or
a residential community with multiple EMAs. It supports energy management by facilitating
interactions among EMAs, appliances, consumer electronics, distributed energy resources
(DER) and electric vehicle (EV) chargers. These EMA functional requirements and interfaces
complement the reference model for interconnected EMAs specified in ISO/IEC 15067-3-3. The
EMA interfaces identify interactions and information exchanges for energy management
applications. The goal of this document is to specify a framework for multiple EMAs to provide
energy management co-operatively by using communication protocols that link devices
participating in energy optimization, transactive energy (TE), and demand response (DR)
programmes, subject to constraints such as a consumer's budget for energy or goals for
reducing greenhouse gas emissions.
This document explains a high-level view of the EMA functional requirements and reference
interfaces in energy environments beyond the traditional public utility. Such energy
environments include energy supplies from DER and TE sources. DER encompasses supplies
from wind turbines, solar panels, and other local power generators, plus storage equipment
(stationary and mobile batteries). Also, the EMA can assist the prosumer (a consumer who also
produces power) in buying or selling TE.
As specified in ISO/IEC 15067-3-3, the EMA can interact with other EMAs, smart appliances,
DERs or other consumer products. Interacting EMA are anticipated to be important for
apartment complexes with multiple apartments and possibly multiple houses or buildings on a
campus. ISO/IEC 15067-3-3 accommodates an EMA per apartment, per building, per campus,
and possibly a cloud-based EMA. Options for interconnecting EMAs to create an EMA
framework (EMF) are specified.
This document and related standards accommodate flexible and efficient energy management
by co-ordinating and optimizing energy consumption and generation within a residential
community consisting of houses and apartments. The ISO/IEC 15067-3 series enables
automated energy management including optimal load control for allocating energy consumption
and generation among multiple products in a house or a small building. The co-ordination among
products offers improved energy management applications and overall efficiency according to
goals set by the occupants. Multiple EMAs organized according to this document will be
especially useful as DER proliferates with fluctuating energy generation and storage.

5 Configuration of multiple energy management agents in a residential
community
5.1 Overview
ISO/IEC 15067-3:2012 specifies the model of a generic energy management system and
specifies the EMA for a house or a unit in an apartment complex. Communicating EMAs in an
apartment building, a residential community house or a small building are introduced in
ISO/IEC 15067-3-3:2019. These EMAs communicate with each other in an EMA framework
(EMF) to optimize energy management among these houses and units (apartments). Figure 1
shows a generalized EMF configuration for houses in a residential community. The EMF
configuration shown in Figure 1 is enabled by the EMAs in each house and the EMA serving
the community, all acting co-operatively to provide energy management for each house and for
the community. EMAs interface with DERs, EVs, and smart appliances (e.g. thermostat,
dishwasher, air conditioner, and heat pump) to optimize energy management within constraints
set by the consumer. Such constraints are personalized by the consumer and can include a
cost budget, limits on greenhouse gas emissions and reduction in the carbon footprint of the
house.
An EMF can also be integrated with a metering system as illustrated in Figure 1. Smart meters
perform automated meter readings and communicate with an advanced metering infrastructure
(AMI) of a utility or energy service provider. The AMI network shown in the network is separate
from other networks because it is often proprietary to a meter manufacturer. Smart meters can
provide utility and consumption data useful for EMAs to management energy within a home or
apartment complex.
In some regions, customers with excess wind and solar power can sell the excess to the local
utility. Some are paid the retail rate for energy; others are paid a special "feed-in tariff" rate.
Such customers who also produce power are called "prosumers". As reported in
ISO/IEC TR 15067-3-7 and ISO/IEC TR 15067-3-8, there is considerable research into the
development of markets and technologies for prosumers to sell excess wind and solar power to
neighbours via a local microgrid or the distribution grid. The process that includes a market and
technologies for prosumers to sell and buy power among themselves, to an aggregator or a
public utility is called transactive energy (TE).
TE is enabled by a local trading market for power with a bid-and-ask mechanism for power to
be delivered now or at a specified future time. However, this is a constrained market because
power must flow from source to load over wires that have capacity limits. Therefore, controls
are needed to manage power flows on a local basis. The EMA could be programmed both for
TE bidding and for managing power flows from the TE supplier to the TE customer's appliances,
EVs, and storage devices. The EMAs can buy and sell energy to a local utility or to other
prosumers (subject to local regulations), as described in ISO/IEC TR 15067-3-7 and
ISO/IEC TR 15067-3-8.
