# Guaranteed Phase & Topology Identification in Three Phase Distribution Grids

@article{Bariya2020GuaranteedP, title={Guaranteed Phase \& Topology Identification in Three Phase Distribution Grids}, author={Mohini Bariya and Deepjyoti Deka and Alexandra von Meier}, journal={IEEE Transactions on Smart Grid}, year={2020}, volume={12}, pages={3605-3612} }

We present a method for joint phase identification and topology recovery in unbalanced three phase radial networks using only voltage measurements. By recovering phases and topology jointly, we utilize all three phase voltage measurements and can handle networks where some buses have a subset of three phases. Our method is theoretically justified by a novel linearized formulation of unbalanced three phase power flow and makes precisely defined and reasonable assumptions on line impedances and…
