摘要
以优化能量流、减少弃风及降低碳排放为前提,针对碳捕集系统和电转气设备,提出一种计及储碳、储氢设备的联合运行模式,并基于该模式构建电气综合能源系统低碳经济调度模型。将该模型转化为混合整数线性规划问题进行求解分析,结果表明:在所提联合运行模式下,电气综合能源系统基本实现了风电的全额消纳,且储碳、储氢设备的加入提高了碳捕集系统、电转气设备的运行灵活性,实现了碳循环,优化了能量流,使系统综合运行成本、碳排放量均为最优。在多能耦合的综合能源系统中,该模型的提出对系统低碳经济运行具有积极意义。
On the condition of optimizing the energy flow,reducing wind curtailment and carbon emissions,this paper proposes a combined operation mode considering carbon storage and hydrogen storage equipment for the carbon capture system and power-to-gas equipment,and constructs a low-carbon economic dispatching model of the integrated power-to-gasenergy system.It transforms the model into a mixed integer linear programming problem for solution and analysis.The results show that under the proposed combined operation mode,the integrated electricity-gas energy system basically realizes full absorption of wind power,and the addition of carbon storage and hydrogen storage equipment improves the flexibility of the operation of carbon capture system and power-to-gas equipment.The proposed mode realizes carbon cycle and optimizes the energy flow,which optimizes the comprehensive operation cost and carbon emissions of the system.In the integrated energy system containing multi-energy coupling,the proposed model is of great significance for low-carbon economic operation of the system.
