MEAN4SG network aims to educate 11 young researchers in the smart grids metrology field by constructing a training network gathering the whole innovation value chain. The main EU actors in the field of smart grids metrology have worked together, under the umbrella of the European Association of National Metrology Institutes (EURAMET), and relying on the support of the International Electrotechnical Commission (IEC), in order to design a training program coping with the principal R&D challenges related to metrology for smart grids while tackling the shortage of highly-skilled professionals on this area that has been foreseen by the European Commission, the electricity grids industrial sector and the academia. The overall MEAN4SG research programme tackles the main research challenges in the smart grids metrology field identified by the European R&D community: (1) power quality analysis, (2) smart grids modelling and management, (3) advanced monitoring through Phasor Measurement Units applications and (4) smart cable diagnosis. These main goals have been divided into eleven specific objectives, which will be assigned to the fellows, for them to focus their R&D project, PhD Thesis and professional career. The established training plan answers the challenges identified by the SET Plan Education Roadmap. Personal Development Career Plans (PCDP) will be tuned up for every fellow, being their accomplishment controlled by a Personal Supervisory Team (PST), composed by a main supervisor from the beneficiary and two mentors from the institutions hosting the two fellows secondments. The training plan includes intra-network activities, like Specific Courses lectured by the project partners, as well as network-wide initiatives, like two secondments for every fellow, PhD Seminars organized in cooperation with EURAMET and Summer Schools. Internal agreements have been reached among the beneficiaries to ensure the access for all the fellows to the obtention of a PhD degree.

Renewable energy sources are key enablers to decrease greenhouse gas emissions and to cope with the anthropogenic global warming. The intermittent behaviour of them and their limited storage capabilities present new challenges to power system operators in maintaining power quality and reliability. However, the increased availability of advanced automation and communication technologies has also provided new intelligent solutions to these challenges. Previous work has presented various new methods to operate highly interconnected power grids with corresponding components in a more effective way. As a consequence of these developments the traditional power system is transformed into a cyber-physical system, a Smart Grid. Previous and ongoing research activities have mainly focused on validating certain aspects of Smart Grids, but until now no integrated approach for analysing and evaluating complex configurations in a cyber-physical systems manner is available. The lack of system validation approaches for Smart Grids is especially addressed by ERIGrid. By providing a Pan-European research infrastructure ERIGrid supports the technology development as well as the roll out of Smart Grid solutions and concepts in Europe. It tackles a holistic, cyber-physical systems based approach by integrating 18 European research centres and institutions with outstanding research infrastructures and jointly develops common methods, concepts, and procedures. ERIGrid also integrates and enhances the necessary research services for analysing, validating and testing Smart Grid configurations. System level support and education for industrial and academic researchers in is provided as well to foster future innovation. ERIGrid addresses these challenging aims by providing a single entry point to the provided research infrastructure and offering a broad spectrum of services to researchers active in Smart Grids. This will strengthen the technical leadership of Europe in the energy domain.

The present invention relates to an electrical coupling device. The electrical coupling device (1) allows coupling between different sets of busbars (2, 3) that are encapsulated or insulated in their corresponding modules (4, 5), such that said coupling is carried out when they are live, i.e., without putting a line connection switchboard comprising the set of busbars (2) out of service. The device (1) allows performing quick and safe electrical coupling, maintaining the protection rating of IP2X at all times.
