The　development　of　a　regional　integrated　energy　system　makes　demand　response　resources　the　means　of　dispatch.　With　demand　response　resources　as　the　subject　of　the　transaction,　this　paper　considers　the　interaction　between　the　system　operator　and　load　aggregator,　and　the　uncertainty　of　renewable　energy　sources,　thus　establishing　a　bi-level　optimization　model　considering　wind　power　correlation　scenarios　and　demand　response,　with　the　upper　and　lower　levels　aiming　at　maximizing　the　net　profit　of　the　system　operator　and　the　load　aggregator,　respectively.　The　bi-level　model　is　converted　to　a　single-level　model　by　KKT　condition　and　convexification,　which　is　solved　using　the　CPLEX　commercial　solver.　The　final　simulation　results　verify　the　feasibility　of　the　method.　©　2023　IEEE.
