本文提出了一个100%的电动汽车（EV）的情况下，在丹麦博恩霍尔姆岛的能源系统的分析。本文旨在提出一个现实的系统将面临的挑战和机遇时，完全转向电动交通。电动汽车采用不同的充电策略，以评估对电网的影响，对充电成本的潜在节省以及对电池退化的影响。与不受控充电相比，智能充电策略的设计不仅要满足电动汽车出发时的相同充电要求，而且要最大限度地节省充电成本并避免互连故障。智能策略使每年的充电成本降低了约12%，此外，由于平均SOC和循环次数较低，还减少了退化。此外，结果显示，由于节省的边际增加，双向充电的益处有限：由于循环次数的增加，这种允许放电的要求更高的操作导致更高的电池退化。
The paper proposes an analysis of a 100% electric vehicle (EV) scenario on the energy system of the island of Bornholm in Denmark. The paper intends to present challenges and opportunities that a realistic system would face when completely shifting to electric transportation. The EVs are subject to different charging strategies in order to assess the impact on the grid, the potential savings on the charging cost and the effects on battery degradation. In contrast to uncontrolled charging, smart charging strategies are designed not only to satisfy the same charging requirements at the EV departure time, but also maximize the savings on the charging cost and avoid interconnection congestions. Smart strategies bring a reduction in annual charging cost around 12%, on top of a reduction in the degradation because of lower average SOC and number of cycles. Moreover, results show a limited benefit in bidirectional charging because of a marginal increase in savings: this more demanding operation, which allows discharges, leads to higher battery degradation, due to the increase in the number of cycles.
