The　integrated　electricity-gas　system　(IEGS)　is　considered　as　an　important　carrier　to　promote　the　new　energy　consumption　and　achieve　the　goal　of　carbon　peaking　and　carbon　neutrality.　To　protect　the　privacy　of　the　electricity　and　gas　networks,　and　tackle　the　problem　of　the　inefficient　solution　process　of　the　IEGS　economic　scheduling　model　caused　by　the　dynamic　characteristics　of　the　gas　network,　a　distributed　low-carbon　economic　scheduling　method　of　the　IEGS　based　on　the　gas　network　division　is　proposed.　Firstly,　the　dynamic　characteristics　of　the　gas　network,　the　carbon　capture　power　plants　emission　reduction　capacity　and　the　carbon　absorption　of　the　power　to　the　gas　devices　are　considered　to　establish　the　IEGS　low-carbon　economic　scheduling　model;　secondly,　the　electricity　and　gas　networks　are　decoupled　according　to　the　boundary　connection　relationship　of　the　IEGS;　thirdly,　the　gas　network　is　divided　and　decoupled　based　on　the　Louvain　algorithm　and　the　node　tearing,　and　the　consensus-based　alternating　direction　method　of　multipliers　is　used　to　solve　the　subregion　optimization　problems　of　the　IEGS　in　parallel;　finally,　the　joint　system　of　the　modified　IEEE39　node　electricity　network　and　the　Belgium　20　node　gas　network　is　simulated,　which　proves　that　the　proposed　method　is　able　to　improve　the　computational　efficiency,　realize　the　decentralized　autonomy　of　the　electricity　and　gas　networks,　and　reduce　the　carbon　emissions　effectively.　©　2023　Power　System　Technology　Press.　All　rights　reserved.
