Reduced-Order Modeling and Stability Analysis of Grid-Following and Grid-Forming Hybrid Renewable Energy Plants

open access: yesEnergies
The control methods of energy systems can be categorized into grid-following and grid-forming types. The grid-following control method relies on grid synchronization and is prone to stability issues in weak grid conditions.

Distributed control of a fault tolerant modular multilevel inverter for direct-drive wind turbine grid interfacing

open access: yes, 2012
Modular generator and converter topologies are being pursued for large offshore wind turbines to achieve fault tolerance and high reliability. A centralized controller presents a single critical point of failure which has prevented a truly modular and ...

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

open access: yesAdvanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

A novel wide-area control for general application to inverter-based resources in power systems

open access: yesInternational Journal of Electrical Power & Energy Systems
The article illustrates the wide-synchronization control, a novel wide-area control for general application to inverter-based resources. The principle is first introduced from a theoretical point of view, including a mathematical proof of the concept, a ...

Diversity of Grid Traffic: A Survey-based Study [PDF]

open access: yes, 2007
Grid computing offers the prospect of harnessing huge amounts of computational resources. However, it is being argued that such potential cannot be fully exploited due to the nature of the Internet architecture which is not suitable for high-speed ...

Experimental and Numerical Modal Analysis of Composite Sandwich Structures Using Surfboards as Model Systems

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...
