In　order　to　rationally　evaluate　the　impact　of　special　user　on　the　cost　of　distribution　network,　its　connection　fee　and　use　fee　on　deep　recovery　mechanism　are　analyzed.　The　connection　fee　is　the　cost　mainly　caused　by　the　premature　network　expansion　due　to　the　connection　of　special　user　and　the　use　fee　is　the　cost　mainly　caused　by　the　network　loss　increase　due　to　the　connection　of　special　user.　Jacobi　matrix　is　used　to　deduce　the　nodal　marginal　capacity　cost　matrix　of　distribution　network　with　loop　configuration　for　calculating　the　connection　fee　of　special　user　on　deep　recovery　mechanism.　The　nodal　loss　sensitivity　of　distribution　network　is　used　to　research　the　use　fee　of　special　user　on　deep　recovery　mechanism.　Case　analysis　verifies　the　effectiveness　of　the　proposed　method.　©　2016,　Electric　Power　Automation　Equipment　Press.　All　right　reserved.
