Calculation of the power demand and the cumulated power
Arithmetic power demand:
Arithmetic calculation of the power demand referred to the actual length of the demand
period. The arithmetic power demand in the instantaneous period remains constant providing
the power is constant.
Cumulated power:
Cumulative calculation of the power referred to the configured length of the subperiod. The
cumulated power in the instantaneous period increases linearly providing the power is
constant.
The energy can be calculated from the cumulated power as follows:
Energy = (cumulated power) • (configured period length)

The values are recorded per demand period or subperiod:
●
Fixed block method
All values are recorded per demand period.
●
Rolling block method
Arithmetic power demand values are recorded per demand period.
Cumulated power demand values and maximum / minimum values are recorded per
subperiod.
