摘要

电动汽车具有不同的充电特性,其多样性要求负载管理策略的发展。为了确保符合电网要求,这些策略必须考虑到每辆电动汽车的充电类型(单相或三相)和功率。本文提出了一种最优负载管理方法,在满足功率和相位不平衡约束的情况下,在容量有限的系统中分配充电功率。该算法辅以充电类型识别方法,该方法在连接时确定每辆电动汽车的特性。基于希腊雅典的真实充电数据的案例研究,研究了不同份额的单相和三相电动汽车以及不同的相位不平衡限制的影响。该方法利用电网规定的允许不平衡水平,在保证电动汽车停车场符合电网运行的同时,最大限度地提高用户满意度,使不平衡极限违规率低于1%,平均能量完成率超过98%。

Grid-friendly operation of EV parking lots: Optimal load management under cluster power and phase unbalance constraints
The diversity of electric vehicles (EVs), each with distinct charging characteristics, necessitates the evolution of load management strategies. To ensure compliance with grid requirements, these strategies must account for each EV’s charging type (single- or three-phase) and power. This paper proposes an optimal load management method to distribute charging power among EVs in capacity-limited systems, while adhering to power and phase unbalance constraints. The algorithm is complemented with a charging type identification method that determines the characteristics of each EV upon connection. A case study based on real-world charging data from Athens, Greece, examines the impact of varying shares of single- and three-phase EVs and different phase unbalance limits. By utilizing the allowable unbalance level defined by grid regulations, the proposed method ensures grid-compliant operation of EV parking lots while maximizing user satisfaction—achieving an unbalance limit violation rate below 1% and an average energy fulfillment exceeding 98%.

期刊介绍: eTransportation is a scholarly journal that aims to advance knowledge in the field of electric transportation. It focuses on all modes of transportation that utilize electricity as their primary source of energy, including electric vehicles, trains, ships, and aircraft. The journal covers all stages of research, development, and testing of new technologies, systems, and devices related to electrical transportation. The journal welcomes the use of simulation and analysis tools at the system, transport, or device level. Its primary emphasis is on the study of the electrical and electronic aspects of transportation systems. However, it also considers research on mechanical parts or subsystems of vehicles if there is a clear interaction with electrical or electronic equipment. Please note that this journal excludes other aspects such as sociological, political, regulatory, or environmental factors from its scope.
