Power Profile Keys

For a load input a PowerProfileKey can be specified. This key is used to map the load input with a power profile during a simulation. The key is normally provided as a String. If this key matches the PowerProfileKey of one of the built-in load LoadProfile, the corresponding load profile will be applied. If no profile should be used, for example when using primary data via a time series, the field needs to be left empty.

Power Profiles

The PowerProfile is an interface that can be used to define power profiles. Each profile needs to have a PowerProfileKey. The data model uses the built-in profiles internally. The LoadProfile is an interface that extends the PowerProfile interface.

To assist the user in marking the desired load profile, the enum BdewLoadProfile provides a collection of commonly known German standard electricity load profiles, defined by the bdew (Bundesverband der Energie- und Wasserwirtschaft; engl. Federal Association of the Energy and Water Industry). For more details see the corresponding website (German only).

Furthermore, there are TemperatureDependantLoadProfiles which can be used to note usage of load profiles for night heating storages or heat pumps for example. The profiles rely on the VDN description for interruptable loads. For more details see here (German only). NbwTemperatureDependantLoadProfiles provides sample temperature dependant load profiles that can be used. The NbwTemperatureDependantLoadProfiles consists of load profiles “ep1” for heat pumps and “ez2” for night storage heating.
