Each Scenario contains a run-time property called ValidOutput. This property indicates whether the Load Shedding Module found a solution that ensures stability to that system due to this Scenario. If it is configured to True, this means that the Load Shedding Module could select a set of available Loads for shedding, ensuring that the selected amount is greater than or equal to the deficit provoked by the occurrence of this Scenario. Some reasons for this property to present a False value are the following:

•Insufficient load available for shedding: This may be due to an excessive number of Loads with priority equal to 0 (zero), a small number of Loads available for shedding, or Breakers configured as unavailable for shedding

•Disabled Scenario: If the Scenario or the Load Shedding Electrical Study have their Enable property set to False

•Configuration failure: If the system is not properly configured or the input Measurements are incorrectly configured
