Item Framework for the integration of active tertiary prosumers into a smart distribution grid(IEEE Computer Society, 2015-09-14) Jimeno, Joseba; Ruiz, Nerea; Tryferidis, Thanasis; Tzovaras, Dimitrios; Tsatsakis, Konstantinos; POWER SYSTEMSThis paper describes the approach taken in the collaborative project INERTIA [1] with the objective of introducing the Internet of Things-Services principles for enabling Demand Response (DR) operations. Nowadays, the continuously increasing presence of distributed intermittent energy sources along with inelasticity of demand pose significant challenges and undoubtedly have considerably negative impact on the overall operation of the electricity grid. Furthermore, the energy market is considered as inherently incomplete and imperfectly competitive mainly due to the characteristics and special nature of the commodity of power. Demand Side Management (DSM) as a supportive mechanism for grid operation and market participation, has the unleashed capacity to overcome some of the major barriers of controlling supply and demand becoming a powerful tool at the hands of Distribution Grid Operators as well as other market stakeholders. The proposed approach uses advanced and innovative Distributed Energy Resources (DER) models, occupancy prediction mechanisms, users' preferences extraction algorithms and DER monitoring and control technologies for making it possible to provide high volumes of demand flexibility without impacting on final user's comfort and DER utility levels. The demand flexibility made available at building level is then aggregated in order to offer significant flexibility volumes with high reliability degree to Distribution System Operators (DSOs) and other energy stakeholders.Item REVIEW OF THE EUROPEAN DWELLING STOCK AND ITS POTENTIAL FOR RETROFIT INTERVENTIONS USING SOLAR-ASSISTED HEATING AND COOLING(University of Cantabria, 2018) Elguezabal, Peru; Arregi, Beñat; Schuetz, Philipp; Gwerder, Damian; Scoccia, Rossano; Tsatsakis, Konstantinos; Biosca, Javier; Bortkiewicz, Anna; Waser, Remo; Sturzenegger, David; Tecnalia Research & InnovationThis study provides a characterization of the existing European stock of residential buildings, with a specific focus on their energy performance. Eight countries with different characteristics and climates have been selected as a representative sample. After identifying relevant parameters, data has been compiled from several sources, including national statistical bodies and European datasets from official and unofficial bodies, as well as previous research projects. Based on those projects as initial source of information, the study is complemented with energy efficiency related regulations as well as with external climate data. The collected information has been subject to a critical review and analysed to identify insights and trends related to the energy performance of European dwellings. The information gathered is intended to provide a general view about the current status for each of the assessed countries and by extension a global picture of the European stock. The outcomes of this study will constitute a realistic baseline scenario for identifying needs, potentials and constraints for renewable energy technologies, and will assist the development of a novel software tool for planning energy-efficient retrofits of residential buildings.Item Review of the European dwelling stock and its potential for retrofit interventions using solar-assisted heating and cooling(University of Cantabria - Building Technology R&D Group, 2018) Elguezabal, Peru; Arregi, Beñat; Schuetz, Philipp; Gwerder, Damian; Scoccia, Rossano; Tsatsakis, Konstantinos; Biosca, Javier; Bortkiewicz, Anna; Waser, Remo; Sturzenegger, David; Villegas, Luis; Lombillo, Ignacio; Blanco, Haydee; Boffill, Yosbel; Villegas, Luis; Lombillo, Ignacio; Blanco, Haydee; Boffill, Yosbel; ECOEFICIENCIA DE PRODUCTOS DE CONSTRUCCIÓN; EDIFICACIÓN DE ENERGÍA POSITIVAThis study provides a characterization of the existing European stock of residential buildings, with a specific focus on their energy performance.
