摘要(Abstract)：

由于环境污染和能源短缺问题的凸显,天然气-电力耦合形成的多能源互联系统因其清洁、高效引起了众多关注。然而天然气系统运行和电力系统运行属于2个不同的时间尺度,其耦合系统运行须考虑这一因素的影响。针对这一问题,推导了天然气系统动态潮流方程,考虑气电联合系统双边能量转换关系,建立了耦合系统的多时段优化运行模型,并在一定假设情况下,对模型进行了合理的线性化处理,使得该模型可以很好地反映耦合系统中天然气侧系统的动态过程,且能适用于大规模问题求解要求。最后通过仿真算例验证了所提模型的合理性和有效性。

关键词(KeyWords)： 气电联合系统;多时间尺度;动态潮流方程;Wenderoff差分;线性优化
