XL-Connect has published a new research paper introducing a scalable energy management framework designed to unlock the potential of Electric Vehicles (EVs) in Renewable Energy Communities (RECs). The concept of RECs, promoted by the European Commission, represents a step toward a more decentralised and participatory energy system. Yet, the rapid growth of EV adoption poses a challenge: uncontrolled charging can significantly increase peak demand and strain local distribution grids.

The new study, “Scalable Energy Management Model for Integrating V2G Capabilities into Renewable Energy Communities” , explores how Vehicle-to-Grid (V2G) technology can transform EVs from passive loads into active contributors to community energy balance. The proposed framework combines day-ahead optimisation through Mixed-Integer Linear Programming with local rule-based controllers that manage real-time deviations, ensuring both efficiency and reliability. By adopting this hybrid approach, communities can reduce their dependence on medium-voltage substations, optimise economic incentives, and enhance internal energy sharing.

Simulation results based on a six-month case study with historical demand and synthetic charging data demonstrate the benefits of this approach. V2G integration led to smoother load curves, with a 15.5% reduction in consumption ramps, a 90% increase in shared power redistributed within the community, and improved alignment with zonal pricing, which strengthens both cost efficiency and system stability.

This work highlights how EV integration through V2G is not only feasible but also vital for the sustainable development of energy communities. By leveraging scalable and cooperative energy management strategies, RECs can achieve greater resilience, efficiency, and independence, helping to build the foundation of a more decentralised European energy system.
