Analysis of a Novel Brushless Doubly Fed Reluctance Generator Based Wind Energy Conversion System

Energy Science &Engineering, EarlyView.
BDFRG based grid connected wind energy conversion system. ABSTRACT This paper presents a grid connected Brushless Doubly‐Fed Reluctance Generator (BDFRG) based wind energy conversion system. It offers a reliable and cost‐effective solution since its brushless and cage‐less rotor structure eliminates the need for slip rings, reducing maintenance costs ...

High‐Fidelity Simulation‐Driven Control Framework for Robust Grid Integration of Renewable Energy Systems

Energy Science &Engineering, EarlyView.
This work proposes a high‐fidelity, simulation‐driven control framework for robust grid integration of hybrid PV–wind systems using a modular, hierarchical multi‐loop architecture with adaptive decision logic. The framework coordinates power, DC‐link voltage, and grid currents under fast load and generation changes, enabling safe exploration of extreme

Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

International Journal for Numerical Methods in Fluids, EarlyView.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly
