煤炭的生产和消费导致甲烷和二氧化碳的排放。高排放成本和部分地区可再生能源有限制约了低碳能源系统的发展。本文提出了一种基于多能源系统的双回收系统，以促进能源效率和减排，考虑煤炭生命周期碳排放和碳交易。建立了一个非线性多目标两阶段随机规划模型，并给出了基于NSGA-Ⅱ的近似求解算法，以寻求不确定条件下系统投资与运行的经济-生态平衡策略。最后，以咸阳市某煤矿为例，验证了模型和算法的有效性。结果表明，当温室气体排放率要求低于0.95kgCO2e/kwh时，多能源双回收系统比单能源系统可获得5%~ 40%的利润。研究发现，碳捕集与封存在获取可交易绿色证书方面具有更广泛的效用，P2 G技术的效率取决于可再生能源的丰富程度。可交易的绿色证书是对煤矿瓦斯利用的有效激励。
Coal production and consumption cause methane and carbon dioxide emissions. The high emission cost and the limited renewable energy in some areas restrict the low-carbon energy system development. This paper proposes a double recovery system based on a multi-energy system to promote energy efficiency and emission reduction, considering the life cycle carbon emissions of coal and carbon trading. A nonlinear multi-objective two-stage stochastic programming model and an approximate solution algorithm based on NSGA-II are built to find the economic-ecological balanced strategy for the system investment and operation under uncertainty. Finally, a case study about the collieries in Xianyang City is adopted to test the effectiveness of the proposed model and algorithm. The results show the multi-energy system with a double recovery system can obtain 5%–40% more profits compared with the single energy system when the GHG emission rate requirement is lower than 0.95 kgCO 2 e/kwh. And this paper finds that carbon capture and storage has more universal utility in obtaining tradable green certificates, and the efficiency of P2G technology depends on the abundance of renewable energy. The tradable green certificates are effective incentives for coal mine methane utilization.
