Aiming　at　the　problems　of　AC/DC　hybrid　distribution　network　node　voltage　instability,　high　rate　of　abandoned　wind　and　photovoltaic　power　and　high　system　operation　and　maintenance　cost　caused　by　source-load　volatility,　a　low-carbon　optimization　operation　method　of　AC/DC　hybrid　distribution　network　taking　into　account　network　reconfiguration　and　demand　response　is　proposed.　Firstly,　a　stepped　carbon　trading　model　for　AC/DC　hybrid　distribution　networks　is　established.　Secondly,　a　low-carbon　optimization　operation　model　for　AC/DC　hybrid　distribution　networks　is　developed　with　the　optimization　objectives　of　system　economy　and　low-carbon,　taking　into　account　the　constraints　of　network　reconfiguration,　demand　response,　capacitor　switching,　ac⁃　cess　to　distributed　power　sources,　and　charging/discharging　of　energy　storage.　Then,　the　nonconvex　distribution　network　optimization　model　is　transformed　into　a　mixed-integer　convex　planning　model　and　solved　by　introducing　intermediate　variables　and　a　second-order　cone　relaxation　method.　Finally,　the　proposed　method　is　simulated　and　analyzed　by　the　improved　IEEE　33-node　AC/DC　hybrid　distribution　system,　and　the　results　show　that　the　proposed　method　can　significantly　reduce　the　carbon　emissions　and　the　rate　of　wind　and　photovoltaic　power　abandonment　generated　by　the　system　operation,　and　improve　the　system　voltage　stability　and　dispatch　economy.　©　2025　Editorial　Department　of　Southern　Power　System　Technology.　All　rights　reserved.
