计及电-氢耦合和绿证-碳交易协同机制的综合能源系统低碳经济调度OA

[Objective]To improve the low-carbon economy of park-level integrated energy systems under the"dual carbon"goals,a bi-level Stackelberg-Nash game optimization scheduling method integrating electricity-hydrogen coupling and green certificate-carbon trading is proposed.[Methods]A multi-energy flow coupling framework is first constructed,incorporating liquid-storage carbon capture,two-stage power-to-gas,and hydrogen-blended natural gas technologies,to achieve multi-energy complementarity and low-carbon synergy.Second,a synergistic green certificate-carbon trading mechanism is established,where green certificate revenues and tiered carbon costs are incorporated into the objective function to form a closed-loop market that incentivizes low-carbon operation.Furthermore,an"operator-user"bi-level Stackelberg-Nash game framework is developed:the upper level sets pricing and scheduling strategies,while the lower level adjusts energy consumption behavior.The game equilibrium is solved using the Alternating Direction Method of Multipliers.[Results]Case studies show that,compared with traditional master-slave game scheduling,the proposed method reduces total system cost by 7.9%and carbon emissions by 10.0%,while effectively improving renewable energy accommodation and multi-stakeholder coordination.[Conclusions]This method provides effective technical support for achieving the"dual carbon"goals in park-level integrated energy systems.
