DIN IEC/TS 62913-2-3:2025-06

The purpose of this document is to define the generic smart grid requirements for resources connected to the electric power systems; namely, distributed energy resources, smart home/commercial/industrial/DR-customer energy management, energy storage, and bulk generation domains - based on the methods and tools developed in IEC SRD 62913-1. Use Case implementations are given for information purposes only. The interface requirements to be considered for later standardization activities are summarized (typically information pieces, communication services and specific non-functional requirements: performance level, security specification, etcetera). On the one hand, electric vehicles are considered DERs and should generally be covered by IEC SRD 62913-2-3; on the other hand, however, for historical reasons, they are divided into two documents and covered by IEC SRD 62913-2-4 in the area of electric transportation. This document captures possible "common and repeated usage" of a smart grid system, under the format of "Uses Cases" with a view to feeding further standardization activities. Use Cases can be described in different ways and can represent competing alternatives. From there, this document derives the common requirements to be considered by these further standardization activities in term of interfaces between actors interacting with the given system.
