A state estimation method based on modifying admittance is proposed, in which by means of modifying the equivalent admittance of injection node, the deviation of admittance is reduced by stepwise iteration. The correctness of the proposed method is proved by theoretical derivation. Simulation results of IEEE 30-bus system show that the proposed method possesses following advantages such as high accuracy, high calculation speed and easy to programme, so it is suitable for state estimation of distribution networks.
