Configuring Aggregation From Children

If a meter group is not directly forecasting its own forecast value, it can be assigned a value based on an aggregation of the forecasts of its children. This may be useful in displaying a forecast value for a logical grouping that does not have any meaningful associated input data, and thus no calculated forecast. An aggregation that is representative of child meter or groups may be useful for reporting purposes. Group aggregation configuration takes the form of an arithmetic expression.

Aggregation can be used to create a multi-directional meter representation. For example, a group can be created with a receipt and delivery meter as children, and an aggregation can be setup for the group that subtracts the receipt meter’s forecast from the delivery meter’s forecast.
