Interaction energy-based power coupling oscillation analysis and suppression of grid-forming converter connected system

open access: yesInternational Journal of Electrical Power & Energy Systems
The power coupling effect of the grid-forming converter will cause instability oscillation when it connects to low-voltage short-distance transmission lines. To solve this problem, this paper presents an energy interaction analysis method for oscillation

3D Heisenberg universality in the van der Waals antiferromagnet NiPS3

open access: yesnpj Quantum Materials
Van der Waals (vdW) magnetic materials are comprised of layers of atomically thin sheets, making them ideal platforms for studying magnetism at the two-dimensional (2D) limit.

A novel protection scheme of wind farm access to flexible DC power grid based on high frequency measurement inductance difference

open access: yesInternational Journal of Electrical Power & Energy Systems
A protection scheme for the DC transmission line of the four-terminal flexible DC grid connected to the doubly-fed wind farm based on the high-frequency measurement inductance difference is proposed.

Giant exchange splitting in the electronic structure of A-type 2D antiferromagnet CrSBr

open access: yesnpj 2D Materials and Applications
We present the evolution of the electronic structure of CrSBr from its antiferromagnetic ground state to the paramagnetic phase above T N  = 132 K, in both experiment and theory.
