Integrated vehicle-to-building and vehicle-to-home services for residential and worksite microgrids

Highlights: The rapid development of electric mobility is introducing novel opportunities and solutions for electric vehicle integration into the electricity system. The integration of several EV-charging scenarios is a key element in defining a novel and smart integration of sustainable mobility systems, providing mutual benefits to EV owners, third parties, and the electricity system. This paper proposes a novel approach to EV-charging’s integration into the house/work routine of an EV owner, providing shared benefits to the owner and the working site, and providing an effective balancing of renewable power fluctuations. The application of the proposed methodology was tested in the experimental facility of the Sapienza University of Rome, considering real data coming from real load, photovoltaic, and storage units. What are the main findings? A novel integrated approach to V2B service; The exploitation of novel EV battery management strategies. What are the implications of the main findings? Improved exploitation of EV capabilities to reduce energy dependency and costs. Novel possibilities to achieve charging cost reduction by providing V2B service and, thus, making EV mobility more sustainable and affordable. The development of electric mobility offers new perspectives in the energy sector and improves resource efficiency and sustainability. This paper proposes a new strategy for synchronizing the energy requirements of home, commercial, and vehicle mobility, with a focus on the batteries of electric cars. In particular, this paper describes the coordination between a battery management algorithm that optimally assigns its capacity so that at least a part is reserved for mobility and a vehicle-to-building (V2B) service algorithm that uses a share of EV battery energy to improve user participation in renewable energy exploitation at home and at work. The system offers the user the choice of always maintaining a minimum charge for mobility or providing more flexible use of energy for business needs while maintaining established vehicle autonomy. Suitable management at home and at work allows always charging the vehicle to the required level of charge with renewable power excess, highlighting how the cooperation of home and work charging may provide novel frameworks for a smarter and more sustainable integration of electric mobility, reducing energy consumption and providing more effective energy management. The effectiveness of the proposed solution is demonstrated in a realistic configuration with real data and an experimental setup.
