IEC SRD 62913的这一部分根据用例启动并说明了IEC的系统方法，包括识别通用智能电网要求，以进一步标准化与电力系统相连的资源，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”的形式捕获了智能电网系统可能的“常见和重复使用”，以便为进一步的标准化活动提供支持。 用例可以用不同的方式描述，并且可以表示相互竞争的备选方案。在此基础上，本文件根据与给定系统交互的参与者之间的接口，导出了这些进一步标准化活动要考虑的共同需求。 为此，给出的用例实现仅供参考。总结了后续标准化活动需要考虑的接口要求（通常是信息片段、通信服务和特定的非功能性要求:性能级别、安全规范等）。 该分析基于领域专家的业务输入，以及智能电网环境中电网管理的现有资料（如果相关）。 表1突出显示了本文档中描述的域和业务用例。 电动汽车一方面被视为DER，通常应符合IEC SRD 62913-2-3；但另一方面，由于历史原因，它们被分为两个文件，并包含在IEC SRD 62913-2-4电力运输领域中。 该文件将随着新版本的发布而更新。表1突出显示了本文档中涵盖的业务领域。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC SRD 62913 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. The document will be updated as new editions are published. Table 1 highlights the business areas covered in this document.All current amendments available at time of purchase are included with the purchase of this document.
