Abstract

This study investigates the impact of increasing electric vehicle (EV) adoption on the power grid in the United Arab Emirates (UAE), focusing on grid performance, stability, and efficiency under different EV penetration scenarios. A mathematical model is developed to evaluate EV charging load profiles based on energy consumption, charging schedules, and station distribution. The results reveal that level 1 (120 V) charging stations generate a peak load of 93.6 kW, whereas level 2 (240 V) stations impose a significantly higher peak load of 187.2 kW. The study finds that while the existing power grid can support up to 40% EV penetration with level 1 charging, it risks exceeding capacity with level 2 infrastructure. By 2030, a 40% EV penetration with level 2 charging is projected to surpass the system’s margin capacity, increasing the likelihood of voltage instability and transformer overloads. This research is novel in its UAE-specific modeling of EV charging impacts, offering detailed insights into grid constraints under future EV growth. To mitigate these challenges, the study recommends dynamic pricing strategies and vehicle-to-grid (V2G) technology to optimize load distribution and enhance grid resilience. The findings provide essential guidance for policymakers, utilities, and industry stakeholders in developing a sustainable and efficient EV charging infrastructure.

电动汽车对阿联酋电网的影响分析
本研究探讨了阿拉伯联合酋长国(UAE)越来越多的电动汽车(EV)采用对电网的影响,重点研究了不同电动汽车普及情景下的电网性能、稳定性和效率。建立了基于能量消耗、充电计划和充电站分布的电动汽车充电负荷评估数学模型。结果表明,1级(120v)充电站产生的峰值负荷为93.6 kW,而2级(240v)充电站产生的峰值负荷明显更高,为187.2 kW。研究发现,虽然现有电网可以在一级充电时支持高达40%的电动汽车渗透率,但在二级基础设施上,它有超过容量的风险。到2030年,40%的二级充电电动汽车普及率预计将超过系统的边际容量,从而增加电压不稳定和变压器过载的可能性。这项研究在阿联酋特定的电动汽车充电影响建模方面是新颖的,为未来电动汽车增长下的电网约束提供了详细的见解。为了缓解这些挑战,该研究建议采用动态定价策略和车辆到电网(V2G)技术来优化负荷分配并增强电网的弹性。研究结果为政策制定者、公用事业公司和行业利益相关者开发可持续、高效的电动汽车充电基础设施提供了重要指导。
