摘要
针对北方农村地区冬季清洁取暖造成局部供电、供气紧张的问题,提出一种计及温控厌氧发酵和阶梯碳交易的农村综合能源低碳经济调度模型。首先,基于沼气厌氧发酵池的热力学模型和温度与产气率的关系,构建沼气发酵的温控模型。然后,采用变压吸附设备提纯分离沼气中的甲烷和二氧化碳,引入电转气消纳其中的二氧化碳,产生甲烷回馈系统。同时考虑农村用户参与碳市场,采用阶梯碳价,分析碳交易基价和价格增长率对农村用能成本和碳排放的影响。最后,以系统运行成本最低为目标函数进行优化求解。仿真分析表明,所提模型可实现系统碳排量降低157.27 kg,运行成本降低11.57%。
There is a problem of local power and gas supply shortage caused by clean heating in winter in northern rural areas.Thus a low-carbon economic dispatch of rural comprehensive energy that takes into account temperature controlled anaerobic fermentation and ladder carbon trading is proposed.First,based on the thermodynamic model of an anaerobic biogas fermentation tank and the relationship between temperature and gas production rate,a temperature control model for biogas fermentation is constructed.Then,pressure swing adsorption equipment is used to purify and separate methane and carbon dioxide from biogas,and electric conversion gas is introduced to absorb the carbon dioxide,generating a methane feedback system.At the same time,considering the participation of rural users in the carbon market,a ladder carbon price is adopted to analyze the impact of carbon trading base price and price growth rate on rural energy costs and carbon emissions.Finally,the problem is optimized and solved with the objective function of minimizing system operating costs.Simulation analysis shows that the proposed model reduces system carbon emissions by 157.27 kg and reduces operating costs by 11.57%.
