Under　the　current　grid　operation　mode,　reasonable　integration　of　wind　power　is　conducive　to　the　exertion　of　its　value.　In　this　paper,　the　line　flow　transmission　margin　value　considering　wind　power　integration　is　assimilated　into　the　locational　marginal　price　(LMP).　Accordingly,　the　LMP　includes　four　components:　energy　consumption,　network　loss,　congestion　and　line　flow　transmission　margin.　Based　on　the　LMP　difference　of　load　nodes　before　and　after　wind　power　integration　and　the　idea　of　power　flow　tracing,　the　specific　values　of　different　grid-connected　wind　farms　at　each　node　are　evaluated,　namely,　the　energy　value　and　the　network　value　of　wind　power.　The　load　nodes　that　have　a　critical　impact　on　wind　power　accommodation　for　each　wind　farm　are　identified.　Moreover,　the　reserve　cost　caused　by　the　uncertainty　of　wind　power　is　considered,　in　which　the　maximum　total　value　of　all　wind　farms　is　set　as　the　optimal　objective.　Finally,　this　paper　analyses　the　LMP,　value　and　accommodation　of　a　single　wind　farm　in　detail　through　a　microgrid　system　and　an　IEEE　118-bus　system　with　multiple　wind　farms　to　verify　the　proposed　method.
