The first wave of the COVID-19 pandemic led to decreases in electricity demand and a rising share of Renewable Energy Sources in various countries. In Germany, the average proportion of net electricity generation via Renewable Energy Sources rose above 55 % in the first half of 2020, as compared to 47 % for the same period in 2019. Given these altered circumstances, in this paper we analyze how the German and other European electricity systems behaved during the COVID-19 pandemic. We use data visualization and descriptive statistics to evaluate common figures for electricity systems and markets, comparing developments during the COVID-19 pandemic with those of previous years. Our evaluation reveals noticeable changes in electricity consumption, generation, prices, and imports/exports. However, concerning grid stability and ancillary services, we do not observe any irregularities. Discussing the role of various flexibility options during the COVID-19 pandemic, a relatively higher grid capacity resulting from a decreased electricity consumption, in particular, may have contributed to grid stability.
新冠疫情的第一波冲击导致各国电力需求下降，可再生能源的占比上升。在德国，2020年上半年通过可再生能源产生的净发电量平均占比超过55%，而2019年同期这一比例为47%。鉴于这些变化了的情况，在本文中我们分析了德国及其他欧洲电力系统在新冠疫情期间的表现。我们使用数据可视化和描述性统计来评估电力系统和市场的常见数据，将新冠疫情期间的发展情况与前几年进行比较。我们的评估揭示了电力消费、发电、价格以及进出口方面的显著变化。然而，在电网稳定性和辅助服务方面，我们未观察到任何异常情况。在讨论新冠疫情期间各种灵活性选项的作用时，特别是电力消费下降导致电网容量相对增加，这可能有助于电网稳定。
