Abstract: While a rapid shift towards electric vehicles (EVs) will contribute to reducing carbon emissions from the transport sector, there are concerns that uncoordinated charging of EVs might impose challenges for the local electricity grid. Our study is the first to investigate this empirically in a country-wide analysis, using data from the country with the highest market share of EVs, namely Norway. We present the regulatory framework in which Norwegian grid companies operate and discuss the possible impact of EV charging. Using panel data on 107 grid companies over the period 2008–2017, we then estimate the effect of local growth in EVs on local grid costs. We find that increases in EV stock are associated with increases in costs which are both statistically and economically significant. However, there is a lot of heterogeneity in these results, where the effect on grid costs are higher for small grid companies in rural areas.

电动汽车密度对当地电网成本的影响：来自挪威的经验证据

摘要：虽然向电动汽车 (EV) 的快速转变将有助于减少交通部门的碳排放，但有人担心电动汽车的不协调充电可能会给当地电网带来挑战。我们的研究是第一个在全国范围内进行实证调查的研究，使用来自电动汽车市场份额最高的国家，即挪威的数据。我们介绍了挪威电网公司运营的监管框架，并讨论了电动汽车充电的可能影响。我们使用 2008 年至 2017 年期间 107 家电网公司的面板数据，然后估计当地电动汽车增长对当地电网成本的影响。我们发现电动汽车库存的增加与成本的增加有关，这在统计上和经济上都是显着的。然而，
