摘      要：This paper proposes a new distributed AC state estimation *** from the popular distributed state estimation(DSE)methods based on area partitioning method,the proposed method is a truly distributed method in which the power system is not required to be divided into smaller areas and a centralized state estimator in each area is not *** order to achieve fully DSE,the information propagation algorithm is introduced in this paper to help the distributed local state estimators share the measurement *** information propagation algorithm is developed based on consensus *** proof of the convergence of the information propagation algorithm is provided in this ***,the AC state estimation method is integrated with the information propagation algorithm to realize the proposed *** proposed method is tested in different standard power system *** results show that the proposed method reaches the similar accuracy as the traditional centralized state estimation methods and performs faster and more accurate than the existing DSE methods.
