Power hardware-in-the-loop testing for multiple inverters with virtual inertia controls
Energy Reports, 2023 Virtual inertia (VI) control schemes implemented in inverter-based resources (IBRs) present a promising solution for mitigating the absence of inertial response in power systems after the decommissioning of synchronous generators (SGs).

Pressure‐Assisted Dimensional Transformation of 2D Hydrogenated Borophene into 0D Boron Quantum Dots
Advanced Functional Materials, EarlyView.Hydrogenated borophene (HB) is transformed into distinct boron nanostructures through a solvent‐free thermal process. Under flowing nitrogen, hydrogen escape promotes reconstruction into B2O3 nanoplatelets, whereas hydrogen‐induced pressure under sealed conditions facilitates fragmentation into boron quantum dots.

Incremental quantities protection schemes with grid-forming inverters
IET Conference ProceedingsOne way forward in the development of protection schemes for power grids with a high penetration of renewable energy, is to assume very little about the sources and operate before the sources have had time to react to the fault. Instantaneous incremental quantities (IQs) are data signals that require very short time windows, while also being rich with ...

Advanced Functional Materials, EarlyView.Resonant standing waves generate large‐area lattices of liquid‐crystal topological defects that are permanently encoded into polymer coatings by photopolymerization. The preserved director architecture produces thermally reconfigurable surface topographies while maintaining programmable optical functionality, demonstrating a scalable strategy for ...
