The Electric Vehicles Management for carbon neutrality in Europe (EV4EU) project will propose and implement bottom-up and user-centric Vehicle-to-Everything (V2X) management strategies creating the conditions for the mass deployment of electric vehicles. The strategies will consider the impact on batteries, in user needs, on power systems, including energy markets integration, and on cities’ transformation. The proposed V2X management strategies will be tested in four demonstration sites, allowing an evaluation of the advanced control methodologies and tools, the definition of the appropriate implementation conditions, and a consolidation of the most promising solutions and corresponding business models. Technology providers will test different V2X management approaches, evaluating their feasibility and adequacy for the existing conditions in cities. System Operators will estimate the impact of V2X on the transmission and distribution levels, proposing new services to profit from V2X flexibility, mitigating the effect of V2X, and supporting the development of both V2X and renewables. Tools and Apps for electric vehicle’ users will be developed to provide valuable information about the use of electric vehicles and available energy services. An open platform that considers interoperability, scalability, security, and privacy requirements will ensure the information exchange between stakeholders and systems. The impact of V2X management strategies in different cities will be evaluated in a co-simulation tool from different perspectives, namely, the power grid, cities constraints (existing parking lots, buildings characteristics, etc.), electric vehicle use patterns, and, finally, V2X management infrastructure. New services (Green Charging, Sharing Charging, and Surge Pricing), Demand Response programs, and flexible capacity contracts will be designed to create benefits for electric vehicle owners and improve the adoption of the services. Finally, a regulatory framework that promotes the adoption of V2X and assures secure and economic power systems management under mass electric vehicle penetration will be proposed.
