摘要
面对高比例可再生能源对电力系统运行所构成的挑战及电力系统碳排放对环境的影响,提出将可逆固体氧化物电池(reversible solid oxide cell,RSOC)和碳捕集系统(carbon capture system,CCS)应用于以混合热电联产(combined heat and power,CHP)系统为主导的综合能源系统(integrated energy system,IES)中,旨在实现IES经济、低碳、灵活的全面优化.首先,构建了RSOC和CCS的运行机制和数学模型,利用RSOC将过剩的可再生能源转移至不足时段再利用,同时缓解了风光出力低谷时CCS的能耗压力.其次,构建RSOC和CCS的IES低碳经济模型,以提升模型的碳减排效益,最小化经济运行成本.最后,以西北某市改进的IEEE-40节点电力系统为例,对7种不同配置场景进行算例分析.仿真结果表明该模型在可再生能源消纳及碳减排性能方面具备优越性,并显著提升了IES的经济性和灵活性.
Abstract
Currently,high proportions of renewable energy are consumed by power systems,resulting in increased carbon emissions that adversely affect the environment.To overcomes these challenges,this study proposes to apply a reversible solid oxide cell(RSOC)and a carbon capture system(CCS)to an integrated energy system(IES),dominated by hybrid combined heat and power(CHP)systems,to achieve economic,low-carbon,and flexible comprehensive optimization of the IES.First,the operating mechanism and mathematical models of the RSOC and CCS are constructed.The RSOC is used to store the excess renewable energy for an indefinite period for reuse,thereby alleviating the energy consumption pressure on the CCS during low outputs of wind and solar power.Second,the IES low-carbon economic model of RSOC and CCS is constructed to improve the carbon emission reduction benefit of the model and minimize the economic operation cost.Finally,an improved IEEE-40 node power system in a city in Northwest China is used as an example and seven different configuration scenarios were analyzed.The simulation results show that the model is effective in reducing renewable energy consumption and carbon emission,and it significantly improves the economy and flexibility of IESs.
