BACH, a Bayesian Optimization Protocol for Accurate Coarse‐Grained Parameterization of Organic Liquids

Advanced Functional Materials, EarlyView.
We present a fully automated Bayesian optimization (BO) protocol for the parameterization of nonbonded interactions in coarse‐grain CG force fields (BACH). Using experimental thermophysical data, we apply the protocol to a broad range of liquids, spanning linear, branched, and unsaturated hydrocarbons, esters, triglycerides, and water.

A comparative study of methods for estimating virtual flux at the point of common coupling in grid connected voltage source converters with LCL filter [PDF]

, 2016
Grid connected Voltage Source Converters (VSCs) with LCL filters usually have voltage measurements at the filter capacitors, while it can be important to control the active or reactive power injection at the grid-side of the LCL filter, for instance at a

LL‐37 Driven Phase Transition and Stacking in Oligolamellar Gram‐Negative Bacterial Membrane Models

Advanced Functional Materials, EarlyView.
This work establishes oligolamellar bacterial membrane models to investigate how LL‐37 disrupts the complex dual‐bilayer architecture of Gram‐negative bacteria. Combining SAXS, cryo‐TEM, electrophoretic mobility measurements, and coarse‐grained simulations, it reveals cardiolipin‐driven phase transitions leading to bicelle‐like structures and membrane ...

Efficient Membranes Made of a Nanohybrid of Fluorine‐Doped Carbon Dots Coupled With Metal Organic Framework for High‐Performance Vanadium Redox Flow Battery

Advanced Functional Materials, EarlyView.
A sulfonated poly(ether ether ketone)‐based hybrid membrane is fabricated with fluorine‐doped carbon dot (FCD) and functionalized metal organic framework (MIL−101−NH2). The novel design reduces unwanted ion crossover while maintaining a sufficient proton transport pathway.

Adaptive-Gain Second-Order Sliding Mode Direct Power Control for Wind-Turbine-Driven DFIG under Balanced and Unbalanced Grid Voltage

Energies, 2019
In a wind turbine system, a doubly-fed induction generator (DFIG), with nonlinear and high-dimensional dynamics, is generally subjected to unbalanced grid voltage and unknown uncertainty.

Optimized Hierarchical Power Oscillations Control for Distributed Generation Under Unbalanced Conditions

, 2017
Control structures have critical influences on converter-interfaced distributed generations (DG) under unbalanced conditions. Most of previous works focus on suppressing active power oscillations and ripples of DC bus voltage.

Grid-connected converter control during unbalanced grid conditions based on delay signal cancellation

International Transactions on Electrical Energy Systems, 2018
Considering the recent trend in the development, it has become very hard to imagine modern power system without the integration of power electronic devices. A grid connected converter will be on the forefront of future energy trading, while simultaneously striving to offer good dynamic behaviour and operation in full accordance with the relevant grid ...
