This document presents the work carried out for the enhancement of the end user emulation platform – created in the line of activity dedicated to interaction with the end user of the project “Application to the electricity system, as expected in evolution (theme 2.2) and also for improve security and resilience of information technologies, peer to peer internet of things” of the three-year period 2019-21 – which acts as a key environment for experimenting with services and functions involving domestic users in the management and market mechanisms of the electricity system.

A central point is the integration of the platform with a blockchain-based local market platform demonstrator, previously developed in the three-year project RdS 2019-21. This allows the testing of market mechanisms for energy and service exchanges within energy communities or with aggregators.

The consideration of blockchain technology also involves the IBSI initiative, which aims to create the first Italian network of blockchain nodes for public utility services, including those in the energy sector. Blockchain has been explored as a tool to certify information on energy exchanges and economic transactions, paving the way for the development of sustainable and renewable energy models, in line with the dynamics of energy communities and collective self-consumption schemes. The activity included the creation of an IBSI node at RSE to allow future experimentation on local energy markets.

Finally, in collaboration with the European InterConnect project, which contributes to the development of the SAREF ontology, the applicability of this data model to the information exchanges of end users is explored. Mapping between SAREF entities and data from second generation electronic meters represents a key step in this activity.

The document is divided into two main parts. The first part delves into blockchain technology, describing the integration of the market demonstrator with the user emulation platform and focuses on the information flow and the methodology for generating energy purchase/sale offers, with particular attention to the determination of the price.

The second part of the document focuses on semantic interoperability in the energy context, presenting the SAREF ontology and its extension to SAREF4ENER. Modeling of domestic devices and information exchanges between users and third parties such as aggregators and DSOs are also presented.
