Sub‐Synchronous Oscillation Suppression Strategy for DFIG Based on Morris‐EFAST Global Sensitivity Analysis and Multi‐Parameter Co‐Optimisation

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
The impedance sensitivity of the doubly‐fed induction generator (DFIG) grid‐connected system with series compensation is analysed using the Morris method and the extended Fourier amplitude sensitivity test (EFAST). A cooperative optimisation approach is proposed to adjust high‐sensitivity parameters, thereby suppressing sub‐synchronous oscillations ...

Studies on the release of neutrophil extracellular traps and IFN-γ as part of the innate immune response to Aspergillus fumigatus and on the fungal stress response via the hybrid sensor kinase TcsC [PDF]

open access: yes, 2012
Aspergillus fumigatus is a saprophytic mold that naturally inhabits the soil. Asexual reproduction yields hardy conidia that circulate in the air and are inhaled daily by humans.

Thermodynamic relations for entropy and temperature of multi-horizons black holes

open access: yes, 2015
We present some entropy and temperature relations of multi-horizons, even including the "virtual" horizon. These relations are related to product, division and sum of entropy and temperature of multi-horizons.

Analysis of reactive power loadability and management of flexible alternating current transmission system devices in a distribution grid using whale optimization algorithm

open access: yesIET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
This paper suggests the optimal placement of different flexible alternating current transmission system (FACTS) devices using various metaheuristic methods associated with effective cost management in the distribution network. The outcomes show that the proposed WOA technique generates more upshot than any other evolutionary algorithms in cost ...
