| Abstract: | The two-level distributed state estimation between East China dispatching center and substation can fully utilize the enormous redundant measurement information in substation,conduct local estimation with high-accuracy,and then process global coordination to improve the real-time state estimation results of the whole network.This paper introduces the experimental construction and application of two-level distributed state estimation system in East China Power Grid.Finally,the comparative study of the state estimation results between experimental substation and dispatching center shows that the state estimation results of the whole network have been evidently improved |
