With　the　development　of　new　energy　on　a　large　scale,　the　application　of　power-to-gas　(P2G)　technology　provides　novel　ideas　for　the　consumption　of　renewable　energy　such　as　wind　power.　This　paper　proposes　a　nonlinear　optimal　model　of　wind　power　accommodation　for　an　electricity-heat-gas　integrated　microgrid　with　P2G,　taking　the　minimum　operating　cost,　the　minimum　wind　curtailment,　and　the　minimum　comprehensive　cost　as　objectives.　On　the　basis　of　meeting　the　demand　for　electricity,　heat　and　gas　loads,　the　security　constraints　of　the　electricity　microgrid,　and　the　gas　network　are　considered　in　connection　with　the　operating　characteristics　of　the　P2G　devices.　The　optimization　software　GAMS　is　used　to　solve　this　model.　Finally,　the　integrated　system　of　a　14-bus　microgrid　and　a　modified　20-bus　gas　network　is　adopted　for　demonstrating　the　effectiveness　of　the　application　of　the　P2G　to　improve　wind　power　accommodation　capability.
