摘要(Abstract)：

在可再生能源渗透率的快速增长背景下,构建电-气综合能源系统具有重要的经济和环保意义。传统电-气综合能源系统模型对电转气(power to gas,P2G)过程处理过于简化,且环保效益考虑不充分。在电-气综合能源系统中,提出带有中间缓冲环节的P2G实现系统—氢能-天然气混合储能系统(hydrogen-gas energy storage system,HGESS),将P2G过程细分为电转氢和电转天然气,并分别与燃料电池和微型燃气机形成高效型和能量型两阶段电-气-电的能量闭环流动圈。然后将HGESS与微网结合,提出计及P2G过程能量转换损失和环境成本的日前经济调度优化模型。算法中分别采用分段线性化和二阶锥松弛方法,对电网潮流和天然气网络潮流非线性边界做线性化处理。最后在算例中采用高、低风电并网渗透率两种场景,结果证明所提HGESS在高、低渗透率下的电-气综合能源系统都具很好的经济性和环保性,具有广阔的应用前景。
