The　existing　studies　made　great　efforts　in　economic　evaluation　and　its　value　assessment　on　wind　power　integration　at　a　macro　level,　which　is　beneficial　to　the　long-term　development　of　wind　power　but　not　constructive　to　the　real-time　operation　and　accommodation　of　wind　power.　This　paper　analyzes　a　comprehensive　value　of　wind　power,　including　fuel-cost　saving,　emission　reduction,　network　value　and　reserve　cost.　According　to　the　concept　of　locational　marginal　prices,　this　paper　proposes　a　improved　model　of　calculating　LMPs.　where　the　Lagrangian　function　and　KKT　are　utilized　to　formulate　the　locational　marginal　value　of　wind　power　at　a　micro　level.　Case　studies　about　the　impact　of　the　cost　of　conventional　generators,　locations　and　line　transmission　margin　on　the　locational　marginal　value　of　wind　power　are　performed　to　show　the　effectiveness　of　the　proposed　approach.　©　2019　IEEE.
