To depict typical fluctuations of the electricity consumption caused by switching of electrical loads in
households, time series of the load with a high temporal resolution are needed. For that reason the guideline VDI
4655 (reference load profiles of single-family and multi-family houses for the use of CHP systems) is used as the
data basis for load consumption [3]. For single-family houses the guideline includes measured data of typical daily
load profiles from several households as one minute average values. To create an annual time series of the load, test
reference years (TRY) of the DWD are necessary. With the TRY of the climate zone 4 (north-east German
lowlands), a load profile for a single-family household was created for an entire year without considering holidays.
The annual electricity demand of the household is determined to be 4 MWh.
