چکیده :

—This paper addresses the challenge of managing electric vehicle (EV) charging within power distribution grids, considering both technical constraints and user preferences. As transport decarbonization increases EV adoption, concentrated charging demand, particularly during peak evening and night hours, threatens to necessitate costly grid upgrades. While Distribution Network Operators are investing in smart charging algorithms to mitigate this, user reluctance to relinquish charging control remains a key barrier. EV owners prioritize having their vehicles charged by the next morning, but also occasionally require fast charging. Our proposed smart charging algorithm addresses this by allowing users to select either ”fast” or ”normal” charging modes. Utilizing real-time household power consumption data, the algorithm calculates available transformer capacity and prioritizes fast charging requests accordingly. Normal charging requests are accommodated within remaining capacity or deferred. This continuous, data-driven approach ensures efficient transformer utilization. Applying the algorithm to a synthesized residential grid using real-world Australian household data demonstrates its superior performance in delivering fast charging compared to existing methods, regardless of EV penetration levels. Importantly, all EV owners, regardless of charging mode selection, are assured of having their vehicles charged by the following morning, though fast charging incurs a premium.
