Research on Dynamic and Steady-State Characteristics of Grid-Following/Grid-Forming Hybrid Control Based on Model Predictive Control

IEEE Open Journal of Power Electronics
With the rapid development of renewable energy, the widespread integration of power electronic devices into power generation systems has led to increased grid impedance and reduced short-circuit ratio (SCR), causing the grid to exhibit characteristics of

Enhanced grid-following BESS control strategy for unbalanced voltage sag conditions

Journal of Energy Storage
Battery energy storage systems (BESS) play a pivotal role in modern power systems, with most implementations found in distribution networks that operate using a grid-following (GFL) approach. However, these networks often experience voltage unbalances that can negatively impact BESS operation.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Operation and control of multiterminal HVDC grids following the loss of an onshore converter

2013 IEEE PES Conference on Innovative Smart Grid Technologies (ISGT Latin America), 2013
A fully operational Multi-Terminal DC (MTDC) grid will play a key role for the creation of AC systems interconnection and to integrate offshore wind farms. Disturbances (at both AC and DC side) may culminate in the sudden disconnection of onshore HVDC-VSC (High Voltage Direct Current - Voltage Source Converter).

A study in grid simulation and scheduling [PDF]

, 2006
Grid computing is emerging as an essential tool for large scale analysis and problem solving in scientific and business domains. Whilst the idea of stealing unused processor cycles is as old as the Internet, we are still far from reaching a position ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Seamless Integration of Grid-Forming and Grid-Following Capabilities in a Single VSI Within a Unified Hybrid Control Framework Under Islanded Conditions

IEEE Access
To achieve seamless integration of grid-forming (GFM) and grid-following (GFL) capabilities in a single voltage-source inverter (VSI) under islanded conditions, this study introduces a unified hybrid control (UHC) scheme with minimal control parameters ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Seamless Transition Control Method of Grid-Connected Inverters Under Unbalanced Voltage Conditions

IEEE Open Journal of Power Electronics
The transition between Grid-Forming (GFM) and Grid-Following (GFL) modes is critical for adapting to changing power grid conditions. These transitions are essential for protecting grid-connected inverter systems and ensuring reliable power supply ...
