摘　　要：为了实现电-气综合能源系统更为协调精确的状态估计,参考电网状态估计方法,基于最大指数绝对值(Maximum Exponential Absolute Value,MEAV)状态估计建立了电力-燃气网络的稳态模型。采用牛顿法作为基本算法,对系统进行能流计算以及MEAV等价模型的求解。最后,通过30个电网节点和22个燃气节点的耦合系统的仿真实验,验证了所提出的方法在获得电-气互联网络准确运行信息和抑制不良数据方面的能力。In order to achieve more coordinated and accurate state estimation of electric-gas integrated energy system,the present work established a steady-state model of electric-gas network based on maximum exponential absolute value(MEAV)state estimation under the inspiration of power grid state estimation method.It carried out calculation of system energy flow and solution of MEAV equivalent model by using Newton method as the basic algorithm.Finally a simulation experiment on a system coupling 30 power grid nodes and 22 gas nodes was performed,demonstrating the utility of the proposed method in obtaining accurate operation information and suppressing bad data when coping with electric-gas integrated networks.
