绿证—碳联合机制下含多类型需求响应和氢能多元利用的综合能源系统优化调度

Optimal dispatching of integrated energy systems with diverse demand response and multifaceted hydrogen utilization under green certificate‑carbon joint mechanism

随着新型电力系统和能源互联的持续推进,构建高效、低碳和经济的能源供应系统对发展双碳战略至关重要。为此,提出一种绿证—碳交易联合机制下考虑多类型需求响应和氢能多元利用的综合能源系统(integrated energy system,IES)优化运行策略。首先,为充分发挥需求侧资源的调节能力,构建含价格型、激励型和替代型的多类型需求响应模型。其次,针对氢能的清洁特性,构建含电制氢、氢制甲烷、氢转热电和天然气混氢的氢能多元利用模型。最后,将绿证交易和碳交易相结合,提出绿证—碳联合交易机制,并构建计及绿证—碳联合交易机制的IES低碳经济运行模型。算例仿真设置不同运行方案对比,验证该文所提模型在提升可再生能源消纳、能源利用效率和降低碳排放量等方面的有效性。

With the continuous advancement of new power systems and energy interconnection,building an efficient,low-carbon,and economical energy supply system is crucial for the development of the dual carbon strategy.To this end,this paper proposes an optimized operation strategy for an integrated energy system(IES)that considers multi-type demand response and diverse utilization of hydrogen under a joint mechanism of green certificate and carbon trading.Firstly,to fully leverage the regulatory capabilities of demand-side resources,a multi-type demand response model is constructed,encompassing price-based,incentive-based,and substitution-based responses.Secondly,considering the clean nature of hydrogen,a diverse utilization model for hydrogen is established,including power-to-hydrogen,hydrogen-to-methane,hydrogen-to-heat/electricity,and blending hydrogen with natural gas.Lastly,by combining green certificate trading with carbon trading,a joint green certificate-carbon trading mechanism is proposed,and an IES lowcarbon economic operation model that takes into account this joint trading mechanism is constructed.The simulation examples,which compare different operational scenarios,verify the effectiveness of the proposed model in enhancing renewable energy integration,improving energy utilization efficiency,and reducing carbon emissions.
