Improvement of Transient Performance in Microgrids: Comprehensive Review on Approaches and Methods for Converter Control and Route of Grid Stability

open access: yesIEEE Open Journal of the Industrial Electronics Society, 2023
In conventional power systems, stability is ensured successfully because of large synchronous generators, where, during transient conditions, the inertia and dynamics of the synchronous generators help to retain stability.

Dynamic Modeling and Vibration Characteristics for a High-Speed Aero-Engine Rotor with Blade Off

open access: yesApplied Sciences, 2021
Blade off that occurs during operation will generate a sudden imbalance excitation and make the rotor become inertially asymmetric, which leads to large instantaneous impact load and induces more complex rotor dynamic phenomena.

Chaotic-based particle swarm optimization algorithm for optimal PID tuning in automatic voltage regulator systems

open access: yesElectrical engineering & Electromechanics, 2021
Introduction. In an electrical power system, the output of the synchronous generators varies due to disturbances or sudden load changes. These variations in output severely affect power system stability and power quality.

Transient Temperature Effects on the Aerothermoelastic Response of a Simple Wing

open access: yesAerospace, 2018
Aerothermoelasticity plays a vital role in the design and optimisation of hypersonic aircraft. Furthermore, the transient and nonlinear effects of the harsh thermal and aerodynamic environment a lifting surface is in cannot be ignored.
