Electrification of transport offers opportunities to increase energy security, reduce carbon emissions, and improve local air quality. Plug-in electric vehicles (PEVs) are creating new connections between the transportation and electric sectors, and PEV charging will create opportunities and challenges in a system of growing complexity. Here, I use highly resolved models of residential power demand and PEV use to assess the impact of uncoordinated in-home PEV charging on residential power demand. While the increase in aggregate demand might be minimal even for high levels of PEV adoption, uncoordinated PEV charging could significantly change the shape of the aggregate residential demand, with impacts for electricity infrastructure, even at low adoption levels. Clustering effects in vehicle adoption at the local level might lead to high PEV concentrations even if overall adoption remains low, significantly increasing peak demand and requiring upgrades to the electricity distribution infrastructure. This effect is exacerbated when adopting higher in-home power charging.

运输电气化为提高能源安全性，减少碳排放和改善当地空气质量提供了机会。插电式电动汽车（PEV）在交通运输和电力领域之间建立了新的联系，而PEV充电将在日益复杂的系统中带来机遇和挑战。在这里，我使用高度解析的住宅用电需求模型和PEV的使用情况来评估不协调的家用PEV充电对住宅用电需求的影响。尽管即使采用较高的PEV水平，总需求的增长也可能微乎其微，但不协调的PEV收费可能会显着改变总体住宅需求的形状，即使在采用率较低的情况下，也会对电力基础设施产生影响。即使总体采用率较低，也可能导致地方采用车辆的集群效应导致PEV集中化，从而极大地增加了峰值需求，并需要升级配电基础设施。当采用更高的家用电源充电时，这种效果会加剧。
