IEC SRD 62913-2-3:20 19（e）基于用例启动并说明了IEC的系统方法，并涉及确定通用智能电网要求，以进一步开展连接到电力系统的资源的标准化工作，即分布式能源、智能家居/商业/工业/DR-客户能源管理、储能和批量发电领域。基于IEC SRD 62913-1中开发的方法和工具。 本文件以“用例”的形式记录了智能电网系统可能的“常见和重复使用”，以期为进一步的标准化活动提供信息。用例可以用不同的方式描述，并且可以代表相互竞争的替代方案。从那里，本文档导出了这些进一步标准化活动在与给定系统交互的参与者之间的接口方面要考虑的共同要求。为此，给出用例实现仅供参考。总结了稍后标准化活动要考虑的接口需求（典型的是信息片段、通信服务和特定的非功能需求:性能级别、安全规范等）。 该分析基于领域专家的业务输入以及相关的智能电网环境中电网管理的现有材料。表1突出了本文档中描述的领域和业务用例。 电动汽车一方面被认为是DER，通常应符合IEC SRD 62913-2-3；但另一方面，由于历史原因，它们被分成两个文件，并包含在IEC SRD 62913-2-4电动交通领域中。

IEC SRD 62913-2-3:2019(E) initiates and illustrates the IEC’s systems approach based on Use Cases and involving the identification of generic smart grid requirements for further standardization work for resources connected to the electric power systems – i.e. 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.
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.
To this end, 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, etc.).
This analysis is based on the business input from domain experts as well as existing material on grid management in a smart grid environment when relevant. Table 1 highlights the domains and business Use Cases described in this document.
Electric vehicles are on one hand considered as a DER and normally should fit in IEC SRD 62913-2-3; but on the other hand, and for historical reasons, they are separated into two documents and covered in the IEC SRD 62913-2-4 electric transportation domain.
