Multiarea Distribution System State Estimation via Distributed Tensor Completion
IEEE Transactions on Smart Grid, 2022 This paper proposes a model-free distribution system state estimation method based on tensor completion using canonical polyadic decomposition. In particular, we consider a setting where the network is divided into multiple areas. The measured physical quantities at buses located in the same area are processed by an area controller.

Measurement Placement in Distribution System State Estimation [PDF]
IEEE Transactions on Power Systems, 2009 This paper introduces a technique for meter placement for the purpose of improving the quality of voltage and angle estimates across a network. The proposed technique is based on the sequential improvement of a bivariate probability index governing relative errors in voltage and angle at each bus.

Choice of estimator for distribution system state estimation [PDF]
IET Generation, Transmission & Distribution, 2009 In this study, a statistical framework is introduced to assess the suitability of various state estimation (SE) methodologies for the purpose of distribution system state estimation (DSSE). The existing algorithms adopted in the transmission system SE are reconfigured for the distribution system. The performance of three SE algorithms has been examined
