Multi-objective decoupling control strategy for low voltage ride through under asymmetrical faults

电力工程技术
For the traditional low voltage ride through control under asymmetrical faults, due to the limited control degrees of freedom, the grid-connected inverter control suffers from the problem of not being able to simultaneously realize the output current ...

Electro‐Steric Ion Confinement in Polyelectrolyte Networks for Robust Nonvolatile Artificial Synapse

Advanced Functional Materials, EarlyView.
Polyelectrolyte stoichiometry governs ion transport and retention in electrolyte‐gated synaptic transistors. A PSS‐rich network creates electro‐steric ion confinement that suppresses ion back‐diffusion and stabilizes channel doping, enabling robust nonvolatile synaptic memory, linear weight updates, and low‐energy operation.

Distance protection based on dynamic phase compensation for offshore wind power low-frequency transmission line

International Journal of Electrical Power & Energy Systems
Asymmetrical faults on offshore wind power flexible low-frequency transmission lines (LFTLs) cause the fault current amplitude and phase to be constrained by weak-source control strategies at both terminals.

Fault Tolerant CCS-MPC for Asymmetrical DTP-PMSM Drives Assisted by Fault Detection Algorithm

IEEE Access
Fault tolerance is a highly desirable feature for safety-critical electric drive applications. This paper proposes an open-circuit fault tolerant model predictive controller (FT-MPC) for asymmetrical dual three-phase (DTP) permanent magnet synchronous machine (PMSM) drives, which is formulated using the continuous control set (CCS) approach.

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

Advanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.
