IEC 62746-4:2024 describes CIM profiles for Demand-Side Resource Interface and is based on the use case shown in Annex A of this document. Schemas associated with this document were generated using the CIM101 UML and leverages the Market package. This document defines profiles complimentary to other standards, namely those in IEC 61970, IEC 61968, and IEC 62325.

Overview

IEC 62746-4:2024 sets forth international standards for the systems interface between Customer Energy Management Systems (CEMS) and power management systems, with a specific focus on the Demand Side Resource Interface. This document, developed by the International Electrotechnical Commission (IEC), outlines CIM (Common Information Model) profiles to support streamlined and interoperable communication between energy management systems on the customer side and those operated by grid or market entities. The scope of IEC 62746-4:2024 centers on interfaces that enable demand-side resources-such as distributed energy resources (DERs), responsive loads, and energy storage-to participate actively in grid management and market operations.

Key Topics

CIM Profiles for Demand-Side Resource Interface The standard specifies CIM profiles generated using CIM101 UML diagrams and leverages the Market package, supporting seamless integration across systems.

Interoperability A main purpose of IEC 62746-4:2024 is to facilitate interoperability between CEMS and wider power management systems at both the operational and market levels, building upon complementary IEC standards (IEC 61970, IEC 61968, IEC 62325).

Resource Modelling The document provides guidance for modelling both individual and virtual (aggregated) resources, including location, capability, qualification, and scheduling.

Information and Reference Models Explains comprehensive information models for resource management, dispatch, commodity pricing, bid/offer, and market interactions.

Message Profiles & Communication Sequences Standardized message profiles and exchange sequences support consistent, automated processes for reporting, scheduling, dispatch, and price communication.

Use Case Driven Contains a practical use case for incentive-based building energy management (Annex A), illustrating the real-world application of the defined data models and message types.

Applications

Integration of Distributed Energy Resources Enables DERs-such as solar panels, batteries, or flexible loads-to communicate their capabilities, receive price signals, participate in bidding/offer processes, and receive operational instructions from grid operators and market actors.

Smart Grid and Demand Response Supports advanced demand response programs by providing structured interfaces for the exchange of operational controls, consumption plans, price notifications, and aggregated resource scheduling.

Virtual Power Plant Operations Facilitates the aggregation of multiple smaller resources (e.g., in residential or commercial buildings) so they can act as a single, market-facing virtual resource for ancillary or reliability services.

Market Participation and Grid Reliability Empowers customer-owned resources to deliver services that enhance grid stability and efficiency, such as peak load reduction, frequency response, and capacity support, through standardized data exchanges.

Enhanced Communication Among Stakeholders Streamlines information exchange among entities such as aggregators, system operators, and service procurement systems, supporting a competitive, flexible, and robust energy ecosystem.

These standards collectively enable unified, CIM-based data exchanges across the energy sector, ensuring that systems deployed under IEC 62746-4:2024 are compatible with leading international practices for smart grid integration and market communication.

IEC 62746-4:2024 offers critical guidance for utilities, aggregators, DER operators, and energy market participants seeking to enable efficient, secure, and standards-based integration of demand-side resources into modern grid and market operations. By supporting common information models and message profiles, this standard helps advance smart energy solutions and grid flexibility on a global scale.
