摘要:

在碳达峰和碳中和背景下,工业园区综合能源系统(integrated energy system,IES)因其较高的灵活性和较低的碳排放受到了广泛关注。为降低工业园区IES的碳排放,并提高工业园区IES的经济效益,构建了考虑富氧燃烧捕集技术与电转氢(power-to-hydrogen,P2H)技术合作以及需求响应机制的工业园区IES系统优化调度模型。首先,该模型通过对火电机组进行富氧燃烧改造来提高系统灵活性,降低火电机组碳排放;其次,通过引入P2H与富氧燃烧电厂合作,不仅提高了风光消纳量,也降低了富氧燃烧电厂供氧压力;然后,通过掺氢设备降低了能量转化过程中的损耗,实现了氢气高位利用;最后,通过引入需求响应,进一步提高IES的灵活性,降低碳排放,并基于此建立了该工业园区IES的最小成本优化调度模型。通过案例研究发现实际碳排放较碳配额低29.60%,验证了该模型的有效性,并分析了部分关键变量对工业园区IES的影响。

Abstract:

Under the background of carbon peaking and carbon neutrality, the integrated energy system (IES) in industrial parks has attracted widespread attention due to its high flexibility and low carbon emissions. To further reduce carbon emissions of the industrial park IES and improve its economic benefits, we develops an optimal scheduling model for the industrial park IES, considering the cooperation between oxy-fuel combustion capture technology and power-to-hydrogen (P2H) technology, and the demand response mechanism. Firstly, the model improves system flexibility and reduces carbon emissions of thermal power units by retrofitting them with oxy-fuel combustion. Secondly, the introduction of cooperation between P2H and oxy-fuel combustion power plants not only increases the absorption capacity of wind and solar energy but also reduces the oxygen supply pressure of oxy-fuel combustion power plants. Then, the hydrogen blending equipment reduces energy loss during the energy conversion process, realizing the high-value utilization of hydrogen. Finally, the introduction of demand response further improves the flexibility of the IES and reduces carbon emissions, based on which a minimum-cost optimal scheduling model for the industrial park IES is established. Through a case study, it is found that the actual carbon emissions are 29.60% lower than the carbon quota, verifying the effectiveness of the proposed model. Sensitivity analysis is conducted to examine the impact of key variables on the industrial park IES.

Key words: integrated energy system, oxy-fuel combustion power plant, incentive-based demand response, thermal efficiency variation, power-to-hydrogen cooperation mechanism
