为提高低碳园区综合能源系统(regional integrated energy system,RIES)的低碳性和可再生能源消纳率,提出一种考虑电转气(power-to-gas,P2G)、碳捕集装置(carbon capture and storage,CCS)和氢燃料电池(hydrogen fuel cell,HFC)协调运行...为提高低碳园区综合能源系统(regional integrated energy system,RIES)的低碳性和可再生能源消纳率,提出一种考虑电转气(power-to-gas,P2G)、碳捕集装置(carbon capture and storage,CCS)和氢燃料电池(hydrogen fuel cell,HFC)协调运行的RIES低碳经济调度方法。首先,根据传统火电机组集中碳排放的特点,加入CCS打造更具灵活性的碳捕集电厂(carbon capture power plant,CCPP)。其次,在两阶段P2G中加入HFC,细化氢能使用,建立P2G-CCS-HFC整体模型,在氢能平衡约束条件下,分析不同设备决策对整体模型优化成本的影响。同时,在供能侧和需求侧分别引入绿证-碳交易和综合需求响应双重市场机制激励。最后,考虑风光不确定性,以风光历史数据为基础,构建考虑场景分析和数据驱动的、以最小化总成本为目标函数的RIES分布鲁棒调度模型。基于算例的仿真结果表明,该方法可有效降低碳排放水平,促进新能源消纳,为区域综合能源系统低碳经济调度等研究提供参考。展开更多
