Abstract
In this paper, we analyze the impacts of major electrical properties, including node con-straints, line limits, and flow direction, on vulnerability assessment of power grid usingseveraltypesofelectricalbetweennessmeasures.Specifically,wefirstproposeasetofnewelectricalbetweennessmeasures,whichtakesintoaccountflowdirectioninpowergrids.Then,theimpactsofmajorelectricalpropertiesonvulnerabilityassessmentofpowergridare analyzed by comparing the identification results of critical components based on theproposedelectricalbetweennessmeasureswiththosebasedontheothertwotypesofelec-tricalbetweennessmeasuresreportedintheliterature,whichtakeintoconsiderationnodeconstraintsandlinelimits,respectively.Analysisresultsshowtheimportantimpactofflowdirectionontheidentificationofcriticalcomponents.Theresultsleadustointroduceasetofcombinedelectricalbetweennessmeasuresthattakeintoaccountnodeconstraints,linelimits,andflowdirectiontogether.SimulationresultsontheIEEE300-bussystemandtheItalianpowergridshowthatthecombinedelectricalbetweennessmeasuresaresuperiorinidentifyingcriticalcomponentsandmoreusefulinassessingpowergridvulnerability.
