scope:

The success of the Smart Grid and Smart Home/Building/Industrial approach is very much related to interoperability, which means that Smart Grid and all smart devices in a Home/Building/Industrial environment have a common understanding of messages and data in a defined interoperability area (in a broader perspective, it does not matter if it as an energy related message, a management message or an informative message). In contradiction, today's premises are covered by different networks and stand alone devices. The scope of NPR-IEC/TR 62746-2 is to describe 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 of this technical report are: - To describe an architecture model from a logical point of view; - To describe a set of user stories that describe a number of situations related to energy flexibility and demand side management as well as an outline of potential upcoming Smart Building and Smart Home scenarios. The set of user stories does not have the ambition to list all home and building (energy) management possibilities, but is meant as a set of examples that are used as input in use cases and to check that the set of use cases is complete; - To describe a set of use cases based on the user stories and architecture. The use cases describe scenarios in which the communication between elements of the architecture are identified; - To further detail the communication, identified in the use cases, by describing the requirements for messages and information to be exchanged. This technical report can also be used as a blue print for further smart home solutions like remote control, remote monitoring, ambient assistant living and so forth.
