Orthogonal Multi‐Swarm Greedy Selection Based Sine Cosine Algorithm for Optimal FACTS Placement in Uncertain Wind Integrated Scenario Based Power Systems

Engineering Reports, Volume 7, Issue 5, May 2025.
Orthogonal Multi‐swarm Greedy Selection Sine Cosine Algorithm (OMGSCA) effectively optimizes FACTS placement and sizing in wind‐integrated power systems, reducing operational costs and power losses while enhancing grid stability. Tested on the IEEE 30‐bus system, OMGSCA outperforms traditional methods, demonstrating superior exploration, exploitation ...

Children's Decisions About How to Negotiate a Virtual Reality Stepping Stones Task

Infant and Child Development, Volume 34, Issue 3, May/June 2025.
ABSTRACT On a daily basis, children make decisions about how to negotiate their physical environment. Sometimes they engage in physical tasks that involve risk, requiring them to judge the safety of how to negotiate the environment safely. Individual differences in children's age, sex, physical size, and personality may impact those decisions.

BPF based Estimation and Mitigation of SSR with SSSC

International Journal of Innovative Technology and Exploring Engineering, 2019
The risk of Subsynchronous Resonance (SSR) may reduce with the hybrid of active and passive series compensations. The hybrid series compensation can be done with Static Synchronous Series Compensator (SSSC) (an active FACTS device) and fixed series capacitor (passive compensation). In this paper, we propose a Band Pass Filter (BPF) based Subsynchronous

Volt/VAr Regulation of the West Mediterranean Regional Electrical Grids Using SVC/STATCOM Devices With Neural Network Algorithms

Wind Energy, Volume 28, Issue 2, February 2025.
ABSTRACT Reactive power compensation is now a challenging issue in maintaining adequate power quality and improving the performance of the transmission system. Many researchers have focused on the behavior of voltage in the unbalanced state, and the majority of the studies have been done with STATCOM. In this study, the increasing power demand in power
