An Optimal Thevenin Equivalent Estimation Method and its Application to the Voltage Stability Analysis of a Wind Hub

IEEE Power & Energy Society General Meeting, 2018
A simplified voltage stability analysis method is to use a static Thevenin equivalent to represent the electrical connection to a load center. Assuming fixed values of the Thevenin voltage and reactance, a power-voltage (PV) curve analysis can be ...

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.
