    Architectures and concepts for smart decentralised energy systems
    (Elsevier, 2021-01-01) Morch, Andrei Z.; Caerts, Chris; Mutule, Anna; Merino, Julia; Tecnalia Research & Innovation
    The idea of creation of more decentralized power system has been circulating for a while, but started to materialise only during the recent years, when massive introduction of support schemes for RES has started to move more and more generation into the distribution network. Apart from the environmental benefits, this has created several challenges for planning and operation of the conventional power system. Furthermore, the growing recognition of necessity for optimization across different energy carriers for example “ETIP SNET Vision 2050" is also pointing towards more and more decentralized system. This chapter presents an overview of the main architectures and concepts for smart decentralized energy systems, through the critical analysis of recent documents such as Pan-European roadmaps (ETIP-SNET) and scenarios (TYNDP2020), results of R&D projects and regulatory documents (“Clean Energy for all Europeans”). The chapter is organized in four parts and starts with background for decentralization: driving forces, trends, and foreseen benefits as well as potential challenges and pitfalls. The second section starts with an overview of different levels of decentralization. The decentralized architecture combined with new ICT infrastructure (including machine learning), opens possibility for new and more efficient control approaches (balancing and voltage). This issue has been studied for example in ELECTRA IRP project, elaborating a cellular structure with dedicated set of novel controls for the power system. This section will further look at the market alternatives and the areas with several unresolved issues and gaps, which must be explored further and require an immediate attention from the research community. The following section will present views of several key stakeholders on decentralization of the power system. It appears that transformation to partially or fully decentralized power system will require certain changes of the present and creation of new roles and responsibilities among actors on the power market. Some of these modifications has been already introduced and formalised in the most recent recast of “Clean Energy for all Europeans.” The section will further present somewhat different opinions about this among the involved stakeholders, which have been expressed in several position papers. The final section makes conclusions and links the content to other chapters of the book.

    SmartNet: H2020 project analysing TSO–DSO interaction to enable ancillary services provision from distribution networks: H2020 project analysing TSO- DSO interaction to enable ancillary services provision from distribution networks
    (2017-10-01) Migliavacca, Gianluigi; Rossi, Marco; Six, Daan; Džamarija, Mario; Horsmanheimo, Seppo; Madina, Carlos; Kockar, Ivana; Morales, Juan Miguel; POWER SYSTEMS
    This study presents an overview of the results obtained during the first year of the SmartNet project, which aims at comparing possible architectures for optimised interaction between transmission system operator (TSOs) and distribution system operator (DSOs), including exchange of information for monitoring as well as acquisition of ancillary services (reserve and balancing, voltage regulation, congestion management), both for local needs and for the entire power system. The results concerning TSO-DSO coordination schemes, market design and information and communication technology (ICT) architectures are shown along with the layout of the three technological pilot projects.

    Technologies and Protocols: The Experience of the Three SmartNet Pilots: The experience of the three smartnet pilots
    (Springer, 2019-10-25) Madina, Carlos; Jimeno, Joseba; Ortolano, Luca; Palleschi, Margherita; Ebrahimy, Razgar; Madsen, Henrik; Pardo, Miguel; Corchero, Cristina; POWER SYSTEMS
    The deployment of technological pilots is of paramount importance for testing and demonstrating the technical feasibility of the concepts described in this book for two main reasons. On the one hand, there are few real-life experiences in the application of these concepts, as TSO-DSO coordination is a relatively new topic. On the other hand, there may be some implementation difficulties which cannot be anticipated by the scenario analysis and CBA. Whenever possible, more than one pilot should be deployed, so that each of them can focus on different parts of the TSO-DSO coordination value chain. In that sense, it is important to demonstrate different potential TSO-DSO coordination schemes, so that issues arising from each of them can be identified. Moreover, it is also important to demonstrate different types of DER, so that their flexibilities can be better assessed and the advantages and disadvantages for real-life implementation can be properly identified and addressed. As a third complementarity aspect, having different technological pilots allows for focusing on different parts of the value chain, so that one of them may take the vision of the TSO or DSO, while another one can focus on the needs of the aggregator or DER owners.
