The webinar is a follow-up to that of 08.04.2014 entitled “The role of the Data Model to Achieve interoperability.”The first part introduces the concept of flexibility of the power system and the role that demand-side management can play in this area. The possible role of the residential customer in this context is then outlined as part of the activities of the Energy@home, which is an association of companies working together to define an “ecosystem” that facilitates the creation of new markets for value-added services post metering for residential.

The communication between the broadband network, the electronic meter and household appliances becomes the instrument for providing consumers with new features necessary for monitoring and control of power consumption. Energy @ home aims to define the technical specifications applicable at the international level and, to this end, it collaborates with and alliances with international standardization bodies to develop appropriate communication protocols and data models. The second part describes the technical approach adopted by the Association of Energy@home for the definition of a common data model, an Home Energy Management “ontology”.

In this context is described the ICT architecture provided for the implementation of demand side management (demand response) and the related standard. The path adopted by Energy@home for the definition of a solution is based on standard reference architecture defined by SGAM developed by the “Smart Grid Coordination Group”.The main reason that has led to consider the SEP 2 Data Model (ZigBee Smart Energy Profile 2) as the basis for the realization of the architecture Energy@home, is primarily motivated by its correlation with the IEC CIM standard.The result of the extension of the model SEP 2 by Energy@home, is contributing to the definition of an ontology of the smart appliances in Europe.
