The document is divided into an introductory chapter describing the main national and international research programs and the main objectives of the three-year project, followed by a description of the structure of the project based on eight lines of action. One chapter is dedicated to each line, divided into several topics, for each of which the main results, objectives and motivations of the research are reported, as well as the development phases of the same and a brief summary of the activities carried out in the previous Annual Implementation Plan (PAR). This is followed by a brief description of the activities carried out in related EU projects and national and international working groups: IEA, CIGRE, EEGI, Smart Grid Coordination Group, IEC, CENELEC, CEI, etc.

Knowledge dissemination was carried out continuously through the publication of articles and presentations at conferences; for details, please refer to the final chapter. Contacts with component manufacturers and electricity grid operators were particularly intensive, such as the collaboration with ANIE, Enel Distribuzione, A2A and ACEA, as well as with telecommunications operators such as Telecom Italia and Vodafone to discuss the integration of electricity and communications networks for the development of smart grids. RSE is also collaborating with A2A on the A2A – CP Lambrate initiative, one of the eight medium-voltage smart grid pilot projects approved by the AEEGSI (now ARERA). RSE is participating in the pilot project by integrating its GD test facility, which is in fact a low-voltage microgrid with a configurable topology made up of different generation systems, storage systems and loads.

The general objective of the project is to study, develop models and test methodologies and technologies suitable for promoting the transition towards active distribution grids, i.e. forms of generation distributed over the territory, with a strong presence of non-programmable renewable sources, managed efficiently and able to guarantee services to the national energy system in terms of security and quality of electricity supply and environmental compatibility.
