Voltage Ripple Content Analysis-Based Passive Islanding Detection Technique for Distributed Generation Systems

open access: yes, 2015
With the increased popularity of distributed generation (DG) in power systems, issues such as unintentional islanding should be efficiently resolved. Islanding condition occurs when part of the electrical power system is disconnected from the rest of the

Negotiating contested spaces and places: Narratives of social suffering and resistance in racialized Cape Town communities

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This study employs a schizocartographic approach to explore community narratives of space, memory, and violence in Kraaifontein, Cape Town. Through participants' accounts, ordinary places—gardens, shops, blocks, sports grounds, and streets—emerge as ambivalent geographies where trauma, resilience, and belonging intersect.

Passive Islanding Detection of Inverter-Based Resources in a Noisy Environment

open access: yesEnergies
Islanding occurs when a load is energized solely by local generators and can result in frequency and voltage instability, changes in current, and poor power quality. Poor power quality can interrupt industrial operations, damage sensitive electrical equipment, and induce outages upon the resynchronization of the island with the grid.
