| “双碳”背景下，考虑电热需求响应并结合市场交易机制有助于综合能源系统低碳经济运行，由此，提出一种电热需求响应配合绿证-碳交易机制的综合能源系统模型并进行低碳经济调度。首先，通过加装储液罐的方式改造碳捕集电厂，建立以碳捕集电厂、电转气设备为主要能源耦合设备的综合能源系统数学模型；其次，为降低系统电热负荷峰谷差，进一步降低高碳排机组出力，引入电热需求响应机制；再次，建立阶梯式碳交易机制与绿证交易机制数学模型并将其引入系统低碳经济调度中；最后，以系统运行成本最小为目标函数建立低碳经济调度模型；算例表明，所提模型在系统总成本全面下降的同时实现了风电全额消纳，大幅提高了系统运行的低碳经济效益。 |

| Under the background of“dual-carbon”,considering the demand response of electricity and heat and combine it with the market trading mechanism can help the integrated energy system to operate in a low-carbon economy,an integrated energy system model with demand response of electricity and heat together with the green certificate carbon trading mechanism and scheduling in a low-carbon economy is proposed. Firstly,the carbon capture power plant（CCPP）is modified by adding carbon dioxide storage tanks（CST）and establish a flexible operation model of the CCPP. Then,a mathematical model of the IES with the CCPP and the power to gas（P2G）equipment as the primary energy coupling equipment is established. Secondly,to minimize the peak-to-valley difference of the system’s electric and thermal loads and further reduce the output of high-carbon emission units,a mathematical model of the demand side’s electric and thermal demand response mechanism is established. Again,a mathematical model of the green certificate-carbon trading mechanism to improve system wind power consumption is established. Finally,the dispatch with an objective function to minimize the cost of operating the system is simulated. The simulation scheme verifies that the proposed model realizes the full consumption of wind power with an overall reduction of the total system cost,significantly improving the system’s low-carbon economic benefits. |
