CL_ISU_EDM_SETTLSTEP_0025 

Calculate Supplier Factors for Each Customer Group

Class derived from CL_ISU_EDM_SETTLSTEP_0001

The process method calculates the supplier and distribution factors for the enhanced analytical procedure. It does this for each customer group based on the current allocation of PoDs to customer groups (synthetic profiles) and non-interval customers’ usage factors.

The aggregated (synthetic) load profile for non-interval customers per customer group and settlement unit must be entered as input parameter (01).

A profile with supplier factors is updated (output parameter 01) for each customer group and settlement unit:

Supplier factors of customer group =

Load profile of customer group per supplier / Total profile of all customer groups

with

Load profile of customer group per supplier =

Synthetic profile * Usage factor of customer group per supplier

A profile with VDEW distribution factors for each customer group (output parameter 02), and a profile with a VDEW supplier factor (output parameter 03) for each settlement unit can be updated if this is necessary based on the VDEW interim results. Output parameters 02 and 03 are only calculated if the parameters have been entered in Customizing for the settlement steps.

The VDEW distribution factors are calculated by addtion the SAO supplier factors for each customer group.

VDEW distribution factors of customer group = Load profile of customer group / total profile of all customer groups

with

Load profile of customer group = Synthetic profile * Usage factor of customer group

Sum of all VDEW distribution factors per ¼ hour is equal to 1.00.

The VDEW supplier factor for each customer group corresponds to dividing the supplier factor of the customer group with the VDEW distribution factor.

VDEW supplier factor =

Supplier factors of customer group / VDEW distribution factors of customer group

For performance reasons, only enter output parameters 02 and 03 in Customizing if necessary based on the VDEW interim results (distribution and supplier factors).

Alternatively, the supplier factor can take on different values every quarter of an hour. This is because the usage factor can be prorated to the day. However, since the calculated and forecasted usage factors that are relevant for settlement are generally identical, the difference is negligible.

Class CL_ISU_EDM_SETTLSTEP_0025 can be derived.
