Fuzzy Logic Controller Based Hybrid Anti Islanding Protection Scheme for Distributed Generators [PDF]

Journal of Renewable Energy and Environment
In this research work, a fuzzy logic controller is designed and implemented for small signal stability analysis and anti-islanding protection on the CEGRE LV system. An activated oscillatory disturbance-type signal injection is required in the algorithm.

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

Advanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

Istraživanje stabilnosti anti-islanding detekcije u multi-DGs sustavu

Tehnički vjesnik, 2015
U radu je predstavljen poboljšani model multi-DGs mikro rešetki za analizu stabilnosti sustava tijekom vezivanja s rešetkom. DGs u sustavu opremljeni su Sandia frequency shift (SFS) shemom kao načinom anti-islanding zaštite. Uvođenjem dužine linije distribucijske mreže, pozitivnog porasta povratne sprege SFSa i distribuiranog dovoda energije, parametri
