Estimating the lost real-time measurements under communication failure for distribution system state estimation

This paper introduces a new technique to estimate the lost measurements due to communication failure by taking advantage of the correlation between real-time measurements. The proposed technique was tested on a 95 bus UKGDS test system which highlights the impact of real-time measurements and communication failure on the performance of the distribution system state estimator. The results showcase the validity of the proposed method in increasing the accuracy of the state estimator under the loss of real-time measurements.
