Power-grid systems constitute one of the most complex man-made spatially extended structures. These operate with strict operational bounds to ensure synchrony across the grid. This is particularly relevant for power-grid frequency, which operates strictly at 50 Hz (60 Hz). Nevertheless, small fluctuations around the mean frequency are present at very short time scales <2 s and can exhibit highly complex spatio-temporal behaviour. Here we apply superstatistical data analysis techniques to…

Statistical characterization of airplane delays
A statistical analysis of arrival delays at several UK airports between 2018 and 2020 is presented, establishing a procedure to compare both mean delay and extreme events among airlines and airports, and identifying a power-law decay of large delays.
Superstatistical modelling of protein diffusion dynamics in bacteria
A statistical model is developed for the diffusive motion of the proteins within the bacterium, based on a superstatistics with two variables that hierarchically takes into account the joint fluctuations of both the anomalous diffusion exponents and the diffusion constants.
Superstatistical two-temperature Ising model.
An approach of the two-temperature Ising model as a prototype of the superstatistic critical phenomena is introduced and an analytic equation for the critical line in the phase diagram is proposed and numerical estimation of the critical exponents illustrates that all points on thecritical line belong to the ordinary Ising universality class.

Effects of demand control on the complex dynamics of electric power system blackouts
The OPA model is extended to include fluctuations in the demand at time scales of the order of minutes, intraday demand variations, and the effect of demand control, finding that demand control effectively reduces the number of blackouts without increasing the probability of large-scale events.
