The active power slack is specified by using the multiple generator slack participation factor in CIM.   In case GeneratingUnit.normalPF is set to one and all other generating units have a zero participation factor the GeneratingUnit which has normalPF equal to one will be the active power slack for the ControlArea to which it belongs. In case multiple generators all these GeneratingUnit(s) have non-zero normalPF, but there must be one  GeneratingUnit per control area that have maximum participation factor (GeneratingUnit.normalPF).
