Generator Resource Parameters

Generator Resource Parameters

The following diagram defines the structure of a Generator Resource Parameters that could be included within a ResParametersSet, using the GenResourceParameters tag:

GenResourceParameters Structure

NormalRRCurveInterval Structure

EmergencyRRCurveInterval Structure

GenResourceParametersDetails Structure

GenResourceParameters Structure

The error tag is used to return one or more errors that may be the consequence of the failure of business or syntax validation rules for Generator Resource Parameter change submittals.

On submission, the following table describes the items used for a ResParametersSet change request.
