The operation effects of a source-side carbon capture power plant (CCPP) and power-to-gas (P2G) equipment do not match. The response range of the load-side traditional demand response strategy is small; and the adjustment period is limited; which leads to the problem that the complementary potential of low-carbon characteristics on both sides of the source and load is not fully utilized. This article proposes an electricity–heat coupling system scheduling strategy considering the complementary low-carbon characteristics of source-load. First; the low-carbon operation characteristics of CCPP and P2G with integrated; flexible operations are analyzed; and a source-side CCPP-P2G comprehensive flexible operation mode is proposed. Second; based on the characteristics of flexible adjustment and mutual substitution of electricity and heat load; a load-side comprehensive demand response method is proposed. Finally; the complementary mechanism of low-carbon characteristics on both sides of the source and load is analyzed; and a low-carbon economic dispatch model of the electricity–heat coupling system is constructed to realize the source–load collaborative low-carbon operations. The simulation analysis verifies that the proposed strategy can give full play to the energy time shift advantages of the source-side CCPP and P2G and improve the economic and environmental benefits of the system operations.
