Variability of Aggregate Consumption at Different TODs in Energy Consumption Data

Abstract:

A variability of energy consumption is the total variance divided by total mean consumption. Real data shows convergence of aggregated variability with the number of customers. We investigate the mathematical reasons of this phenomenon, as well as the subtleties of convergence rate. We show that the results for convergence on real data are consistent with the prediction of a simple sum of random correlated variables.
