Abstract: Deepening the coupling of energy, carbon and green certificate markets can not only decrease greenhouse gases emission and promote green energy absorption, but also contributes to the realization of low-carbon transformation for integrated energy system. This paper proposes a novel double-direction interaction mechanism for carbon and green certificate, and studies an energy–carbon–green certificate integrated pricing method. Firstly, the linkage relation of electricity–gas–carbon is analyzed according to the carbon emission differences for different sources of electricity and natural gas. Secondly, a double-direction interaction mechanism between carbon and green certificate is established based on the carbon emission reduction property of green certificate and the promoting green electricity property of carbon emission quota. Combining the above two points, a more complete and closer linkage relations among electricity, gas, carbon and green certificate are constructed. Thirdly, carbon tax and multi-interaction intensity indexes are introduced to develop an integrated pricing method for energy–carbon–green certificate. Finally, five optimal interaction scheduling models are solved. The simulation results verify the feasibility of the proposed interaction mechanism and integrated price on accelerating low-carbon operation, lowering operating cost and reducing the dependence on external networks. And the total cost and carbon emission decrease by 12.65% and 3.04%, and renewable energy absorption rate increases by 4.06%.
