In-grid　wind　power　has　been　a　challenging　problem　in　power　system　due　to　its　high　volatility　and　low　efficiency.　The　wind　power　acceptance　must　be　first　considered　before　a　wind　farm　is　planned　to　be　built.　There　are　many　factors　effecting　wind　power　acceptance,　such　as　wind　turbine　type,　PCC　load　capacity,　regional　load　characteristics,　etc.　A　large　amount　of　research　show　that　wind　farms　have　significant　influence　on　the　local　grid　voltage　level,　so　the　primary　factor　of　wind　power　acceptance　is　voltage　normally.　In　the　study,　the　impact　of　power　system　operation　mode　on　wind　power　acceptance　is　discussed　by　analyzing　the　voltage　variation.　The　combination　of　power　flow　calculation　and　engineering　method　is　utilized　to　evaluate　the　wind　power　acceptance.　The　power　flow　and　engineering　calculation　indicate　that　higher　supply　voltage　and　lower　load　lead　to　higher　acceptance　of　wind　power.　©　2017　IEEE.
