Loss MW
Indicates the real power losses incurred within the super area.
ED Use PF
Indicates whether the power flow engine will calculate loss penalty factors in computing the
economic dispatch solution for the super area. If loss penalty factors are not calculated, then the
economic dispatch is calculated assuming that the super area is lossless. Otherwise, the economic
dispatch solution incorporates losses. The penalty factors gauge the sensitivity of the area’s losses to
changing injection at specific generators. The option to calculate loss penalty factors is relevant only
when the super area operates according to Economic Dispatch Control. Usually, if the system’s cost
curves are relatively flat, the inclusion of losses in the solution will not have much of an effect on the
dispatch.
