Sumario: Duetotheincreasingpenetrationofinverter-basedresources(IBR)inmodernpower grids,mostphasor-domainmodelsbecameinsufficienttorepresentthesystemdynamics duringsteady-stateandfaultconditions.Asaresult,IBRtime-domainmodelsgained importance.However,completemodelsthatincludeswitchingelementsandtheirrespective controllersareusuallytime-consuminganddifficulttoinitialize,especiallyinsystems withseveralIBRsconnected.Thus,thisworkpresentsanequivalenttime-domaingridfollowinginverter-basedgenerator(IBG)model,whichcanbeusedinElectromagnetic TransientsPrograms(EMTP).TheproposedIBGmodelisdevelopedintheAlternative TransientsProgram(ATP)usingtheATPDrawgraphicalinterface.Acompletebenchmark photovoltaicmodelavailableinATP/ATPDrawenvironmentistakenasreferenceto evaluatetheproposedequivalentIBGmodelundersteady-stateandfaultscenarios.The obtainedresultsshowedthattheproposedmodelissimplerandlesstime-consumingthan thecompletemodel,beingcapableofeasilyconsideringtheimplementationofdifferent components/controlsofIBRinEMTP.Thesettingsusedintheimplementedcontrol schemesprovedtobeeffective,resultinginanaverageerrorofabout2.21%duringfault conditions.Also,areductionofabout70%intheexecutiontimewasachievedwhen comparedtotheanalyzedbenchmarkone,attestingitsusefulnessforpowersystemstudies withhighpresenceofgrid-followingIBRs.
