Abstract: The simultaneous expansion of electric vehicles (EVs) and intermittent renewable energy sources holds the potential to accelerate the decarbonization of highly emissions-intensive sectors. However, these developments also pose challenges to the stability of power systems, which could impede their widespread adoption. Nevertheless, electric vehicles present a significant opportunity to enhance flexibility, enabling better integration of renewable energy variations and optimization of energy markets. To address these challenges, there is a need to design new models that incorporate both electric vehicle traffic flows and battery charge dynamics. These models represent a crucial step towards utilizing e-flexibility, a concept aimed at predicting the spatial and temporal evolution of EVs’ state of charge in relation to the electrical grid and associated electricity market operations. The presentation introduces a graph-based approach to model the mobility of electric vehicles and the evolution of their state of charge in large-scale urban traffic networks.
This model combines the vehicles’ mobility, described by dynamic equations over a graph that captures origin-destination movements, with the energy consumption associated with their mobility patterns. The model also incorporates power inputs from charging stations. We will showcase the operation of these models using our numerical twin (eMob-Twin) on the open-to-public platform emob-twin.inrialpes.fr. This model can be extended to account for driver behavior in determining when and where to charge, considering factors such as the current state of charge, distance to charging stations, and charging costs. Moreover, it can be used to identify optimal locations for charging stations, maximizing convenience for EV users and profitability for charging station owners. We will also introduce a simplified (averaged) version of the model, which serves as a foundation for optimizing charging station locations while reducing computational complexity. Lastly, we propose an innovative approach that utilizes aggregated EVs for grid-balancing services in the auxiliary market. This is done by an optimization framework that establishes pricing strategies to maximize profits for aggregators and CSOs while minimizing charging costs for EV users. Our findings demonstrate the effectiveness of this strategy in realistic simulations, integrating EV mobility and the Electricity FCR market.
