摘要(Abstract)：

薄弱节点辨识是综合能源系统安全分析的关键环节。首先从拓扑结构角度考虑,引入最大流和M-阶邻居数的概念,综合考虑线路和管道最大传输容量,电、气、热等值阻抗等多重因素,从全局和局部描述了节点"桥接"和"收发"能力;其次从运行状态考虑,依据泰尔熵原理,将异质能源进行分区,根据各区潮流和压力的变化程度和系统的承受裕度,构造了反映潮流和压力冲击均衡度的改进泰尔熵指标。综合考虑拓扑结构和运行状态,并结合气网、热网延迟响应特性,构造了辨识薄弱节点的评价指标。最后以某一典型的综合能源系统为例,验证了所提方法的有效性和合理性。

关键词(KeyWords)： 综合能源系统;供能可靠性;泰尔熵;最大流;薄弱节点
