Title:TransientVoltageQuantitativeAssessmentMethodforDistributionNetworkswithHighPenetrationWindPower
Abstract:
Theincorporationofhigh-penetrationwindpowerintodistributionnetworksintroducessignificantchallengesforpowersystemoperators,especiallyintermsoftransientvoltagestability.Thispaperproposesanovelapproachforquantitativelyassessingthetransientvoltageperformanceofdistributionnetworkswithahighpenetrationofwindpower.Themethodtakesintoaccountthecharacteristicsofwindpoweroutputanditsimpactonvoltagequalityindistributionnetworks.Byevaluatingthetransientvoltageprofile,thisassessmentmethodcanprovidevaluableinsightsfornetworkplanningandoperation.
1.Introduction
Withtheincreasingdeploymentofwindpowergeneration,distributionnetworksareexperiencinghigherpenetrationlevelsofwindenergy.However,theintermittentnatureofwindpoweranditsfluctuatingoutputposechallengestothetransientvoltagestabilityofdistributionnetworks.Toensurereliableandstableoperation,acomprehensiveassessmentmethodisneededtoquantifytheimpactofhigh-penetrationwindpowerontransientvoltageperformance.Thispaperaimstofillthisresearchgapbyproposinganovelapproachforevaluatingandquantifyingthetransientvoltagestabilityofdistributionnetworkswithahigh-penetrationwindpower.
