Online Thevenin’s Equivalent Using Local PMU Measurements

RE&PQJ
This paper presents a method for determining Thevenin’s Equivalent (TE) for a node in a power system using local PMU measurements at that node. Three consecutive voltage and current measurements are used to determine the TE. The proposed method recognizes and considers the phase angle drift caused by the slip frequency between the PMU sampling ...

Experimental demonstration of an atomtronic battery

New Journal of Physics, 2017
Operation of an atomtronic battery is demonstrated where a finite-temperature Bose–Einstein condensate stored in one half of a double-well potential is coupled to an initially empty load well that is impedance matched by a resonant terminator beam.

Least Squares based Estimation of Thevenin Equivalent in Noisy Distribution Grid

CoRR
This work presents a novel approach that synergizes the extremum seeking method with an online least squares estimation technique to accurately estimate Thevenin equivalent circuit being seen at each node in distribution grids. Thevenin's theorem offers a simplified representation of electrical networks, critical for the effective monitoring, control ...
