Emergent Spin Hall Quantization and High‐Order van Hove singularities in Square‐Octagonal MA2Z4

Advanced Physics Research, EarlyView.
Square‐octagonal MA2Z4 (M = Mo/W, A = Si/Ge, Z = pnictogen) monolayers are predicted to realize quantum spin Hall insulators with nearly quantized spin Hall conductivity enabled by an emergent spin U(1) quasi‐symmetry. Materials with Z = As and Sb host quasi‐flat bands with high‐order van Hove singularities near the Fermi level, making them promising ...

Enhancing Stability of Grid-Following Inverter for Renewables

2023 22nd International Symposium on Power Electronics (Ee), 2023
The increasing penetration of wind and solar power sources in power networks has led to the need for advanced converters' control technologies to support the integration of these renewable energy sources into the grid. Inverters play a critical role in power networks, and understanding the benefits and limitations of different inverter types can ...

Grid-Following Inverters and Synchronous Condensers: A Grid-Forming Pair?

2020 Clemson University Power Systems Conference (PSC), 2020
As power systems across the globe continue to achieve higher instantaneous penetrations of power electronic converter-interfaced renewable sources, the stability of these power systems is challenged because of the removal of synchronous machines, from which stability is traditionally derived.

Self-Synchronization Scheme for Network of Grid-following and Grid-forming Photovoltaic Inverters

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
Microgrids in power electronics dominated grid (PEDG) should be able to operate under islanded and grid-connected modes and switch between them seamlessly. During the islanding events severe fluctuations in voltage and frequency of the microgrid may arise that can cause unstable operation and ultimately blackout.
