Mobility in Switzerland currently consumes about 35% of the total energy demand. While internal combustion engines still generate most of it, the increasing number of electric vehicles changes the landscape by decoupling energy production from consumption. This allows using more sustainable energy sources, such as photovoltaics (PV), hydroelectric power plants or wind turbines. In the past years, the number of PV installations has grown rapidly in Switzerland. It is expected that PV has the highest growth potential of all renewable energy sources. Solar panels are especially interesting, as they can be installed on most buildings, which distributes the electricity production. However, due to frequent fluctuations in production, PV poses a challenge for the existing power grid. It is unclear to what extent PV production can be increased without the need for extensions of the power grid, such as additional transmission lines or storage capabilities. Electric vehicles could be used to consume fluctuating electricity production. In this paper, we study the effects of using locally produced photovoltaic power to recharge electric vehicles of commuters in individual Swiss municipalities. Such an analysis not only gives us indications of the potentials and limits of using photovoltaics to satisfy mobility energy demands, but can also be used to better direct subsidies and plan the electrical grid.

利用当地生产的光伏能源为电动汽车充电

瑞士的机动性目前消耗了总能源需求的35％。尽管内燃机仍占大部分，但越来越多的电动汽车通过将能源生产与消费脱钩而改变了现状。这允许使用更可持续的能源，例如光伏（PV），水力发电厂或风力涡轮机。在过去的几年中，瑞士的光伏装置数量迅速增长。预计光伏在所有可再生能源中具有最高的增长潜力。太阳能电池板特别有趣，因为它们可以安装在大多数建筑物中，从而分配电力。但是，由于生产中的频繁波动，光伏对现有电网构成了挑战。尚不清楚在不扩展电网的情况下（例如额外的输电线路或存储功能）可以将光伏生产提高到何种程度。电动汽车可以用来消耗波动的电力生产。在本文中，我们研究了在瑞士各个城市中使用本地生产的光伏电源对通勤者的电动汽车进行充电的效果。这种分析不仅为我们提供了使用光伏技术满足移动能源需求的潜力和局限性的指示，而且还可以用于更好地指导补贴和规划电网。我们研究了在瑞士各个城市使用本地生产的光伏电源为通勤者的电动汽车充电的效果。这种分析不仅为我们提供了使用光伏技术满足移动能源需求的潜力和局限性的指示，而且还可以用于更好地指导补贴和规划电网。我们研究了在瑞士各个城市使用本地生产的光伏电源为通勤者的电动汽车充电的效果。这种分析不仅为我们提供了使用光伏技术满足移动能源需求的潜力和局限性的指示，而且还可以用于更好地指导补贴和规划电网。
