A Current Limiting Strategy to Improve Fault Ride-Through of Inverter Interfaced Autonomous Microgrids [PDF]

open access: yes, 2017
With high penetration of distributed energy resources (DER), fault management strategy is of great importance for the distribution network operation. The objective of this paper is to propose a current and voltage limiting strategy to enhance fault ride ...

Conformational Trajectory of the Molecular Chameleon Grazoprevir from Formulation to Target‐Bound

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Macrocycles represent a promising class of beyond‐rule‐of‐5 (bRo5) therapeutics, capable of targeting proteins traditionally considered undruggable by conventional small molecules. Macrocycles exhibit intrinsic flexibility and often display a “chameleon‐like” ability to adapt to their environment, thereby enhancing their oral bioavailability ...

Active distribution power system with multi-terminal DC links [PDF]

open access: yes, 2015
A fast power restoration operational scheme and relevant stabilizing control is proposed for active distribution power systems with multi-terminal DC network in replacement of the conventional normal open switches. A 9-feeder benchmark distribution power

Boards of Directors That Transform: A Study on How Specific Architectural Components Drive ESG Performance

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores the potential influence of key components of the board of directors' architecture on ESG outcomes. Specifically, we focus on the effects of demographic components (gender and cultural diversity), structural and compositional factors (size, CEO‐Chair separation, and the presence of independent/non‐executive directors), and ...

Effects of joint geometric configurations on cyclic shear behavior of intermittent joints under constant normal stiffness conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
The present manuscript explored the effects of joint configurations on the cyclic shear behavior of intermittent joints for the first time. The cyclic shear response, shear strength degradation, dilation characteristics evolution, frictional property, fractal dimension, and dissipative energy were further analyzed during shear cycles, which is crucial ...

Transient Equivalent Modelling of a Wind Farm Based on QPSO-Based Wind Turbine Fault Ride-Through Control

open access: yesEnergies
At present, the equivalent modeling method of wind farms mostly adopts single-machine multiplication equivalence, which has the deficiencies of large model error and difficulty in accurately reflecting the fault transient characteristics of wind farms ...

Enhanced AC voltage and frequency control of offshore MMC station for wind farm connection [PDF]

open access: yes, 2018
Connecting large offshore wind farms using HVDC transmission systems based on modular multilevel converter (MMC), the offshore AC voltage and frequency are regulated by the offshore MMC station and are important for the stable wind power generation and ...

Distributed PLL-based control of offshore wind turbines connected with diode-rectifier based HVDC systems [PDF]

open access: yes, 2017
A distributed PLL-based frequency control is proposed in this paper for offshore wind turbine converters connected with diode-rectifier based high-voltage-direct-current (HVDC) systems. The proposed control enables a large number of wind turbines to work
