Attributes

Name Type Description
baseFlow Float Branch base Power Flow.
BGLimit Float This value is determined in DA and RTM. The SCUC optimization ensures that the MW flow on the Branch Group will not exceed this limit in the relevant direction.
BGTRResCap Float Branch Group TR Reservation Capacity - This value is determined in DA and RTM. It is the amount of spare transmission capacity that is left for the TR holder to use.
bindingLimit Float MW Limit.
clearedValue Float Cleared MW.
competitivePathConstraint YesNo Non-competitive path constraint Flag"(Y/N) indicating whether the shadow price on a non-competitive path was non-zero.
constraintType ResultsConstraintType Type of constraint.
limitFlag ConstraintLimitType Limit flag (‘Maximum’, ‘Minimum’).
optimizationFlag YesNo Included in optimization Y/N.
overloadMW Float Transmission overload MW.
percentMW Float Actual MW flow as percent of limit.
shadowPrice Float Shadow Price ($/MW) for the commodity. Shadow price for the corresponding constraint.
updateTimeStamp DateTime Update time stamp.
