论文摘要
电能系统吸引了越来越多样化的研究社区的广泛关注。已经做出了许多理论预测，从波动的缩放定律到骚乱的传播速度。但是，为了验证任何理论，大规模电力系统的经验数据是必要的，但很少公开共享。在这里，我们分析了三大洲12个同步区域的17个位置的电力网格频率测量的开放数据库。功率电网频率特别感兴趣，因为它表明供求的平衡，并带有有关确定性，随机和控制影响的信息。我们对记录数据进行广泛的分析，比较不同的同步区域并验证先前猜想的缩放定律。此外，我们展示了从局部独立振荡变为同质批量行为的波动如何变化。总体而言，提出的开放数据库和分析构成了朝着更多共享，协作的一步
The electrical energy system has attracted much attention from an increasingly diverse research community. Many theoretical predictions have been made, from scaling laws of fluctuations to propagation velocities of disturbances. However, to validate any theory, empirical data from large-scale power systems are necessary but are rarely shared openly. Here, we analyse an open data base of measurements of electric power grid frequencies across 17 locations in 12 synchronous areas on three continents. The power grid frequency is of particular interest, as it indicates the balance of supply and demand and carries information on deterministic, stochastic, and control influences. We perform a broad analysis of the recorded data, compare different synchronous areas and validate a previously conjectured scaling law. Furthermore, we show how fluctuations change from local independent oscillations to a homogeneous bulk behaviour. Overall, the presented open data base and analyses constitute a step towards more shared, collaborative
