Our survey data from Germany indicate that residential PV decision makers are influenced primarily by stakeholders to whom they ascribe beneficial attributes. The data further show that key attributes vary along the decision making process: integrity and likeability demonstrate the strongest association with influence strength at the awareness stage, while availability and trustworthiness have the strongest association at the planning stage. The perception of the competence of the stakeholder is associated with greater influence across all stages.}, language = {en} } @article{GunkelBergaentzleGrastedJensenetal., author = {Gunkel, Philipp Andreas and Bergaentzl{\´e}, Claire and Gr{\ae}sted Jensen, Ida and Scheller, Fabian}, title = {From passive to active: Flexibility from electric vehicles in the context of transmission system development}, series = {Applied Energy}, volume = {277}, journal = {Applied Energy}, issn = {1872-9118}, doi = {10.1016/j.apenergy.2020.115526}, pages = {115526 -- 115526}, abstract = {Electrification of transport in RES-based power system will support the decarbonisation of the transport sector. However, due to the increase in energy demand and the large peak effects of charging, the passive integration of electric cars is likely to undermine sustainability efforts. This study investigates three different charging strategies for electric vehicle in Europe offering various degrees of flexibility: passive charging, smart charging and vehicle-to-grid, and puts this flexibility in perspective with the flexibility offered by interconnections. We use the Balmorel optimization tool to represent the short-term dispatch and long-term investment in the energy system and we contribute to the state-of-the-art in developing new methodologies to represent home charging and battery degradation. Our results show how each step of increased charging flexibility reduces system costs, affects energy mix, impacts spot prices and reduces CO2 emissions until the horizon 2050. We quantify how flexible charging and variable generation mutually support each other (>100 TWh from wind and solar energy in 2050) and restrict the business case for stationary batteries, whereas passive charging results in a substitution of wind by solar energy. The comparison of each charging scheme with and without interconnection expansion highlights the interplay between European countries in terms of electricity prices and CO2 emissions in the context of electrified transport. Although the best outcome is reached under the most flexible scenario at the EU level, the situation of the countries with the cheapest and most decarbonised electricity mix is damaged, which calls for adapted coordination policy at the EU level.}, language = {en} } @article{AndreasGunkelKlingeJacobsenBergaentzleetal., author = {Andreas Gunkel, Philipp and Klinge Jacobsen, Henrik and Bergaentzl{\´e}, Claire-Marie and Scheller, Fabian and M{\o}ller Andersen, Frits}, title = {Variability in electricity consumption by category of consumer: The impact on electricity load profiles}, series = {International Journal of Electrical Power \& Energy Systems}, volume = {147}, journal = {International Journal of Electrical Power \& Energy Systems}, issn = {1879-3517}, doi = {10.1016/j.ijepes.2022.108852}, pages = {108852 -- 108852}, abstract = {Residential electrification of transport and heat is changing consumption and its characteristics significantly. Previous studies have demonstrated the impact of socio-techno-economic determinants on residential consumption. However, they fail to capture the distributional characteristics of such consumer groups, which impact network planning and flexibility assessment. Using actual residential electricity consumption profile data for 720,000 households in Denmark, we demonstrate that heat pumps are more likely to influence aggregated peak consumption than electric vehicles. At the same time, other socio-economic factors, such as occupancy, dwelling area and income, show little impact. Comparing the extrapolation of a comprehensive rollout of heat pumps or electric vehicles indicates that the most common consumer category deploying heat pumps has 14\% more maximum consumption during peak load hours, 46\% more average consumption and twice the higher median compared to households owning an electric vehicle. Electric vehicle show already flexibility with coincidence factors that ranges between 5 and 15\% with a maximum of 17\% whereas heat pumps are mostly baseload. The detailed and holistic outcomes of this study support flexibility assessment and grid planning in future studies but also the operation of flexible technologies.}, language = {en} } @article{DomenigSchellerGunkeletal., author = {Domenig, Christoph and Scheller, Fabian and Gunkel, Phillipp Andreas and Hermann, Julian and Bergaentzl{\´e}, Claire-Marie and Lopes, Marta AR and Barnes, Jake and McKenna, Russell}, title = {Overcoming the landlord-tenant dilemma: A techno-economic assessment of collective self-consumption for European multi-family buildings}, series = {Energy Policy}, volume = {189}, journal = {Energy Policy}, doi = {10.1016/j.enpol.2024.114120}, pages = {114120 -- 114120}, language = {en} }
