Title:ADiscussionontheAssessmentStandardsforUnbalanceofResistanceinHighCapacityPowerDistributiontoDirectCurrentConversion
Introduction:
Withtheincreasingdemandforrenewableenergysources,therehasbeenasignificantriseintheuseofhighcapacitypowerconversionsystemsfordirectcurrent(DC)applications.Thesesystemsplayacrucialroleinconvertingalternatingcurrent(AC)intoDCforvariouspurposes,suchasenergystorage,electricvehiclecharging,andgridintegration.However,itisessentialtoassesstheunbalanceofresistanceinthesesystemstoensureoptimalperformanceandreliability.ThispaperaimstoexploreanddiscusstheassessmentstandardsfortheunbalanceofresistanceinhighcapacitypowerdistributiontoDCconversion.
1.ImportanceofResistanceUnbalanceAssessment:
Inpowerdistributionsystems,resistanceunbalancecanresultinunequalloadsharingamongparallelpowerconverters.Thisimbalancecanleadtounevencurrentdistribution,increasedlosses,reducedsystemefficiency,andpotentialequipmentfailures.Therefore,itiscrucialtoestablishassessmentstandardstomitigatetheseissuesandachieveareliableandefficientpowerconversionsystem.
2.ConsiderationsforAssessingResistanceUnbalance:
