The　complementary　and　coordinated　operation　of　comprehensive　energy　multi-microgrid　groups　belonging　to　different　subjects　is　considered　to　be　an　effective　means　of　cascade　utilization　and　deep　coupling　between　different　energies,　which　is　of　great　significance　for　the　consumption　of　new　energy　and　the　realization　of　the　goal　of　dual　carbon.　Firstly,　considering　the　distant　transportation　of　hydrogen　energy　and　the　demand-side　carbon　emission　reduction,　this　paper　establishes　a　comprehensive　energy　multi-microgrid　system　scheduling　model　considering　the　gas　network　hydrogen　doping　to　further　strengthen　the　coupling　relationship　between　different　energy　sources.　Secondly,　a　dynamic　hydrogen　price　mechanism　based　on　the　time　distribution　of　electric　load　and　the　level　of　new　energy　consumption　is　proposed　to　guide　hydrogen　fuel　cell　vehicles　to　charge　in　an　orderly　manner.　While　the　demand　for　electricity　is　flattened,　the　users　will　also　charge　their　vehicles　more　during　the　period　of　high　curtailment.　Then,　by　decoupling　the　comprehensive　energy　multi-microgrid　model,　the　system　is　distributed　to　obtain　the　global　optimal　operation　strategy　by　the　regularized　alternating　direction　multiplier　algorithm　with　the　adaptive　step　link.　Finally,　the　analysis　shows　that　the　proposed　dispatch　strategy　is　able　to　increase　the　consumption　of　renewable　energy　by　81.48%,　reduce　the　carbon　emissions　by　35.21%,　and　decrease　the　charging　cost　of　hydrogen　fuel　cell　vehicle　users　by　1.58%　under　the　premise　of　regional　autonomy.　©　2023　Power　System　Technology　Press.　All　rights　reserved.
