Microscopic Fluctuations in Power-Grid Frequency Recordings at the Subsecond Scale
Complex systems, such as the power grid, are essential for our daily lives. Many complex systems display multifractal behavior, correlated fluctuations and power laws. Whether the power-grid frequency, an indicator of the balance of supply and demand in the electricity grid, also d...

| description | Complex systems, such as the power grid, are essential for our daily lives. Many
complex systems display multifractal behavior, correlated fluctuations and power
laws. Whether the power-grid frequency, an indicator of the balance of supply
and demand in the electricity grid, also displays such complexity remains a
mostly open question. Within the present article, we utilize highly resolved
measurements to quantify the properties of the power-grid frequency, making
three key contributions: First, we demonstrate the existence of power laws in
power-grid frequency measurements. Second, we show that below one second, the
dynamics may fundamentally change, including a suddenly increasing power
spectral density, emergence of multifractality and a change of correlation
behavior. Third, we provide a simplified stochastic model involving positively
correlated noise to reproduce the observed dynamics, possibly linked to
frequency-dependent loads. Finally, we stress the need for high-quality
measurements and discuss how we obtained the data analyzed here. |
