摘要
提出一种考虑电转气(P2G)、碳捕集系统(CCS)和氢燃料电池(HFC)的“以气定热”整体建模方式。考虑P2G的碳-氢耦合过程,构建P2G-CCS-HFC(PCH)联合运行框架;提出“以气定热”建模方式,建立PCH整体模型,同步分析其电、热、气和碳能量耦合特性;基于PCH、热电联产机组、燃气锅炉和储能设备,构建考虑碳交易机制的综合能源系统(IES)低碳经济调度模型;设置多个运行场景,验证PCH对碳减排的贡献度。仿真结果表明,采用在“以气定热”建模方式下的PCH模型可以较大程度降低IES整体碳排放量和IES运行成本。
A holistic modeling approach of“setting heat with gas”considering power-to-gas(P2G),carbon capture system(CCS)and hydrogen fuel cell(HFC)is proposed.Considering the carbon-hydrogen coupling process of P2G,the joint operation framework of P2G with CCS and HFC(PCH)is constructed.The“setting heat with gas”modeling approach is proposed,based on which the integral model of PCH is established and its energy coupling characteristics of electricity,heat,gas and carbon are analyzed synchronously.Based on PCH,combined heat and power units,gas-fired boilers and energy storage devices,the low-carbon econo-mic scheduling model of integrated energy system(IES)considering carbon trading mechanism is constructed.Several operation scenarios are set to verify the contribution degree of PCH to carbon emission reduction.Simulative results show that the PCH model under the modeling approach of“setting heat with gas”can reduce the overall carbon emissions and operation costs of IES to a large extent.
