## config_timeseries¶

The config file `config_timeseries.cfg`

holds data to define the two worst-case
scenarions heavy load flow (‘load case’) and reverse power flow (‘feed-in case’)
used in conventional grid expansion planning, power factors and modes (inductive
or capacitative) to generate reactive power time series, as well as configurations
of the demandlib in case load time series are generated using the oemof demandlib.
