The demo case has investigated different approaches to analysis of smart meter data in a way to identify different consumption patterns.

The demo case used data from Syd Energi, which had data from about 270.000 smart meters, with 15 minutes to 1-hour resolution and recorded for approximately one year. The idea was that the classification and characterization of electricity consumption should have to give a more detailed picture of consumption patterns to use for estimation and dimensioning of the energy grid.

But the demo case has shown that the model we normally use to define clustering of consumers consumptions does not work: The smart-meter consumption data are not stable from one week to another. So the consumers change over time.
