JWG 3 - SyC Smart Energy/JWG 3

IEC SRD 63460:2025 The scope of this document is the assessment of how Electric Vehicles (EVs) may (or must) act as Distributed Energy Resources (DER) when they are interconnected to the electric power system through a charging station. Although clearly the main purpose for EV interconnection to the grid is to charge their batteries, EVs are capable of providing grid support functions while interconnected, and in some situations, may be mandated or incentivized to do so. This document provides Use Cases as examples of how EVs might provide such DER functionality, based on the grid support functions defined in IEC 61850-7-420, IEEE 1547:2018, and EN 50549.

IEC SRD 63268:2020(E) depicts a comprehensive standardization landscape of the interfaces between the main grid stakeholders and the grid users, grid users comprising DERs and Customer Premises.
This document considers the main "physical" and "logical" interactions (i.e. through wires/functions – power and/or communication) between grid users and grid stakeholders, both from an electrical standpoint and from a data standpoint. Then for each interaction type, the document presents the standardization landscape.
This document depicts, as well, the interactions between the grid stakeholders manipulating grid user related data, themselves. Effectively it appears that considering the sole landscape of the interfaces between the grid users and the grid would be very limited without considering the way the data attached to grid users are manipulated/managed within and between the different stakeholders holding these data. Providing a seamless vision of the management of these data is becoming of highest priority.
The document focuses exclusively on Distribution grid users, excluding as such "bulk generation" grid users and "transmission connected grid users", the main reason being that the main breakthrough resulting from the introduction of distributed energy resources affects mostly the Distribution grid users.
This document mostly focuses on establishing the standardization landscape for the considered domain, including the IEC entities involved in producing reports, technical specifications and standards related to it. From this assessment a first set of recommendations is issued related to the way IEC addresses this scope.

IEC/TR 63097:2017(E) provides standards users with guidelines to select a most appropriate set of standards and specifications. These standards and specifications are either existing or planned, and are provided by IEC or other bodies also fulfilling use cases.
It also aims at creating a common set of guiding principles that can be referenced by end-users and integrators who are responsible for the specification, design, and implementation of Smart Energy Systems.
As a living document, this roadmap will be subject to future changes, modifications and additions, and will be incorporated into future editions.
At the current stage, the focus remains the “Smart Grids”. This means that the full Smart Energy scope has not been addressed yet (i.e. the consideration necessary to include the interactions with other energies such as gas, and heat) and will be considered in a future edition of this document.
