Abstract As the distribution network structure becomes increasingly complex, this paper proposes a distributed state estimation for distribution network with phasor measurement units (PMUs) information to improve the performance of state estimation. This proposed method takes the PMU installation locations as alternative points of the partition, and takes the scale of sub-zone, the number of real-time measurement, and the DG configuration position as the partition criteria, and then conducts distributed state estimation. During the state estimation, the root bus voltage and branch current are used as state variables to reserve the advantage of measurement conversion technology, and the traditional measurement data and PMU measurement data are converted into corresponding currents, which simplifies the Jacobian matrix, thereby reducing iterations and improving the calculation speed of state estimation. Finally, the IEEE 69-bus radial distribution network is used to verify the effectiveness of the proposed method.
