The Entity column defines a valid bus number or a loadflow area (by AreaName) to be assigned to the Hub. The Bus Number column is still valid and if the Entity column is not present in the table (or does not contain a value) then it will be used. If the Entity column is in the table and the Entity Type is as well then these columns will be used first.
If the bus is not a valid bus in the current loadflow case, then a warning will be printed to the Status Window and it will be ignored. If it is ignored and there are other valid buses, then all weights will be normalized and prices for the hub will be calculated as if the bus was not included in the hub definition. If none of the buses in the same hub are in the loadflow case, then the entire hub will be ignored.
NOTE: Weights assigned to loadflow areas are assigned to all buses within the area for reporting. Furthermore, if duplicate buses/areas are assigned to the same hub only the first bus/area in the list will be used, the others ignored.
