Balance deviation data
The class diagram below presents the balance deviation data stored by Datahub.
It is important to note that in the calculation of balance deviation, each individual balance deviation always involves two suppliers. For both suppliers, the balance deviation is always equally large but opposite in sign (positive for one supplier and negative for the other). Therefore, the total energy and monetary value of all balance deviations always sums to zero for each calculation run.
The reason for each balance deviation is determined based on the event that caused it:
Correction of metering data: A correction to metering data reported by the DSO.
Correction of supplier information (balance information correction):
The balance responsibility of an accounting point has been transferred from one supplier to another.
A supplier has been added to an accounting point previously without a supplier.
An accounting point is left without a supplier.
In cases of metering data correction, supplier addition or supplier removal, the counterpart for the balance deviation is the loss supplier for the metering grid area.
