Steady-state voltage stability assessment of new energy power systems with multi-quadrant power modes

Energy Reports, 2023
The “source–load” attributes of the nodes in a new energy power system are complex and diverse due to a large amount of new energy access. The node power (active and reactive power) in the system can offer a changing mode, which causes several serious ...

Phase retrapping in a pointlike $\varphi$ Josephson junction: the Butterfly effect

, 2013
We consider a $\varphi$ Josephson junction, which has a bistable zero-voltage state with the stationary phases $\psi=\pm\varphi$. In the non-zero voltage state the phase "moves" viscously along a tilted periodic double-well potential. When the tilting is
