IEC TR 62746-2:2015（EN）描述了互操作性的主要支柱，以帮助不同的技术委员会定义其接口和信息，覆盖智能电网和智能家居/建筑/工业区之间的整个链条。本技术报告涵盖的主要主题是:从逻辑角度看架构模型；一组用户故事，描述与能源灵活性和需求侧管理相关的许多情况；基于用户故事和架构的用例集；沟通的细节；通过描述要交换的消息和信息的需求，在用例中识别。

IEC TR 62746-2:2015(EN) describes the main pillars of interoperability to assist different Technical Committees in defining their interfaces and messages covering the whole chain between a smart grid and smart home/building/industrial area. The main topics covered by this technical report are: architecture model from a logical point of view; set of user stories describing a number of situations related to energy flexibility and demand side management; set of use cases based on the user stories and architecture; details of the communication; identified in the use cases, by describing the requirements for messages and information to be exchanged.
