IEC SRD 62913-2-2:20 19（E）基于用例启动并说明了IEC的系统方法，并涉及基于IEC SRD 62913-1中开发的方法和工具，为市场相关领域的进一步标准化工作确定通用智能电网要求。 它以“用例”的形式捕捉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）。

IEC SRD 62913-2-2:2019(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 market related domains, based on the methods and tools developed in IEC SRD 62913-1.
It captures possible “common and repeated usage” of a smart grid system, under the format of “Use 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 terms 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.).
