For　the　low　carbon　economic　operation　problem　of　power　system，a　collaborative　optimization　method　for　the　configuration-operation　of　coal-fired　power　plants　with　carbon　capture　considering　low-carbon　demand　response　is　proposed.　The　operation　data　of　solvent-based　carbon　capture　coal-fired　power　plants　is　collected　on　the　gCCS　platform，taking　into　account　the　strong　coupling　relationship　between　the　power　generation　system　and　the　post-combustion　carbon　capture　system.　The　model　parameters　are　identified　by　multiple　linear　regression　method，and　the　corresponding　steady-state　mathematical　model　is　constructed.　The　carbon　emission　flow　theory　is　used　to　calculate　the　carbon　emission　cost　on　the　load　side，and　the　carbon　quota　is　allocated　according　to　the　carbon　emission　intensity　of　generator　units.　And　then　a　low-carbon　demand　response　model　is　established.　On　this　basis，the　upper-level　optimization　model　takes　the　lowest　power　plant　configuration　cost　as　the　objective　function　to　meet　the　capacity　optimization　allocation　constraints.　The　lower-level　optimization　model　with　the　goal　of　minimizing　operating　cost　is　established　to　meet　the　system　operation　constraints.　The　simulation　analysis　is　implemented　on　the　modified　IEEE　24-bus　system，by　which　the　effectiveness　of　the　proposed　strategy　is　verified.　©　2024　Electric　Power　Automation　Equipment　Press.　All　rights　reserved.
