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 inte-grated networks.
