摘要
多能流系统耦合调度相比独立调度可以有效降低运行成本,提高可再生能源消纳,目前已经成为一大研究热点。但是,现有的研究大多采用稳态的热网和天然气网模型,这一方面忽略动态特性中蕴含的调度灵活性,另一方面还可能导致调度结果不准确,引发安全问题。该文基于统一能路理论,建立一种新的电–热–气耦合多能流系统优化调度模型,将描述热网和天然气网络动态的复杂偏微分方程转化为线性复代数方程,易于优化求解。此外,统一能路模型是基于偏微分方程的解析解推导的,具有高精度。算例表明,文中建立的优化调度模型可以利用热网和天然气网的动态特性来提高调度灵活性,降低系统运行成本。相比已有方法,文中建立的优化调度模型具有求解速度快、模型精度高的优点。
