插电式电动汽车（PEV）市场渗透率的提高将使交通运输部门转向更可持续的能源选择。然而，PEV电池充电代表了对电力系统的显著额外负担，特别是在配电水平，其中网络的径向结构可能会加重负载变化的影响。此外，不协调的PEV充电可能导致变压器经常超出其热极限运行，增加其故障的可能性。基于分布式控制方法的协调充电已经被提出作为减轻电压波动和Transformer过载的手段。最近的研究可以分为两类：研究静态PEV负载对配电网的影响，以及开发控制算法，改变PEV充电以实现特定目标。本文结合这两个想法，通过分析配电网潮流动态响应一个大的人口协调PEVs。IEEE 34节点配电测试馈线与PEV车队下的加法增乘法减（AIMD）控制进行了模拟。所得到的方案确保满足所有负载，同时控制PEV需求以满足次级考虑，例如电压调节和Transformer容量限制。然而，在某些条件下可能会产生有害的振荡。本文探讨了这些不必要的变化的原因。
Increased market penetration of plug-in electric vehicles (PEVs) will enable a shift in the transportation sector towards more sustainable energy options. However, PEV battery charging represents a significant additional burden on power systems, especially at the distribution level where the radial structure of the network may accentuate the effects of load variations. Furthermore, uncoordinated PEV charging could cause transformers to regularly operate beyond their thermal limits, increasing their likelihood of failure. Coordinated charging, based on distributed control methods, has been proposed as a means of mitigating voltage fluctuations and transformer overloads. Recent research can be divided into two categories: studies into the effects of static PEV loads on distribution networks, and development of control algorithms that vary PEV charging to accomplish specific goals. This paper combines these two ideas by analyzing distribution network load flow dynamics in response to a large population of coordinated PEVs. An IEEE 34-node distribution test feeder is simulated in conjunction with a fleet of PEVs under Additive-Increase Multiplicative-Decrease (AIMD) control. The resulting scheme ensures that all loads are satisfied, while controlling PEV demand to meet secondary considerations such as voltage regulation and transformer capacity limits. However, detrimental oscillations may develop under certain conditions. The paper investigates the cause of these unwanted variations.
