The task of the algorithm is to calculate the power trend and the power consumption correction . On the basis of consumed power measuring period (cumulative power), the instantaneous power and the measuring period time, the power trend is calculated. The power trend is the expected power at the end of the measurement period. With this power trend a power correction can be calculated. The calculated power correction determines whether devices need to be connected or not.
The calculation is based on each of the readings recorded during the calculated interval. This leads e.g. the number of scheduled intervals for each calculation interval to a different Slope of the trend curve.
The power trend calculation is the projection of the instantaneous power at the end of the Measurement period. Assuming that the power until end of the measurement period does no longer
change, this means that the slope remains constant. The following two figures show the power Trend calculation in graphical form:
With the adjustable calculation interval the reaction speed of the algorithm is set in seconds.
