Abstract

The rapid increase in electric vehicle (EV) adoption introduces significant operational challenges for low-voltage distribution networks. This study evaluates the impact of increasing EV penetration on a real residential distribution feeder in Afyonkarahisar, Türkiye, and investigates the effectiveness of different mitigation strategies. Simulations are conducted using the OpenDSS under multiple EV penetration scenarios, focusing on voltage deviations, thermal loading, and violation durations. The results reveal that thermal (ampacity) constraints become binding earlier and more severely than voltage limits as EV penetration increases. Uncoordinated time-of-use (TOU) charging is shown to increase load coincidence, leading to higher peak currents, whereas conservation voltage reduction (CVR) provides only limited mitigation under high loading conditions. In contrast, centralized charging coordination based on Open Charge Point Protocol effectively reduces peak demand by distributing charging sessions over time. Furthermore, battery storage systems (BSS) significantly mitigate thermal violations by providing localized peak shaving support. Quantitative results indicate that coordinated charging reduces the number of thermal violations substantially, while BSS deployment enables the network to accommodate higher EV penetration levels without exceeding operational limits. The findings highlight the critical role of coordinated charging and energy storage in enabling high EV integration and provide practical insights for distribution system operators in planning and managing future low-voltage networks.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
