A Grid-Aware Agent-Based Model for Analyzing Electric Vehicle Charging Systems
Existing simulation models struggle to simultaneously capture user charging behavior, charging infrastructure constraints, and grid interactions, limiting systematic evaluation of electric vehicle (EV) charging systems. This work proposes a grid-aware multi-agent discrete-event simulation framework that, for the first time, couples user-level charging dynamics with facility-level grid responses and introduces a shared energy sandbox mechanism to enable aggregated power regulation. The model integrates heterogeneous EV behaviors, charger constraints, and real-time power allocation algorithms, supporting flexible configuration of infrastructure and scheduling strategies. Experiments in a representative workplace scenario demonstrate that the combination of charging strategies and charger types significantly affects service performance, facility utilization, and grid load, underscoring the high degree of scenario dependency in infrastructure design and deployment.
