摘要

为解决能源转型过程中面临的碳排放量高、供气不足等难题,提出一种含碳捕集电厂-电转气-液化天然气协同的综合能源系统优化调度模型。首先,考虑碳捕集电厂和电转气设备的“碳耦合”以及液化天然气站的“电-气耦合”,构建含碳捕集电厂-电转气-液化天然气的电气热综合能源系统模型;其次,引入阶梯型碳交易机制,提出碳捕集电厂-电转气-液化天然气协同运行的综合能源系统低碳经济调度模型;最后,以云南某大型工业园区为例,验证所提模型能够有效提高系统的风光消纳水平和能源利用效率,具有显著的低碳经济效益。

Abstract

Promoting the utilization of carbon capture power plants and liquefied natural gas contributes to addressing the challenges of high carbon emissions and inadequate gas supply in China's low-carbon energy transition. Therefore, this paper proposes an optimized scheduling model for an integrated energy system involving the synergy of carbon capture power plants, power-to-gas, and liquefied natural gas. Firstly, considering the “carbon coupling” of carbon capture power plants and power-to-gas equipment, as well as the "electric-gas coupling" of liquefied natural gas stations, an electricity-gas-thermal integrated energy system model is constructed, encompassing carbon capture power plants, power-to-gas, and liquefied natural gas. Secondly, by introducing a stepped carbon trading mechanism, a low-carbon economic scheduling model is proposed for the coordinated operation of an integrated energy system involving carbon capture power plants, power-to-gas, and liquefied natural gas. Finally, using a large industrial park in Yunnan province as a case study, it was confirmed that the proposed model can effectively enhance the integration of wind and solar energy into the system and improve energy utilization efficiency, resulting in significant low-carbon economic benefits.
