Voltage Sag Evaluation in Power Grids Considering the Voltage Support Capabilities of Doubly-Fed Wind Farms During LVRT

open access: yesIEEE Transactions on Power Delivery
This paper introduces how doubly-fed wind farms can compensate for reactive power demands of the grid during low voltage ride through (LVRT) events, thereby providing voltage support. This capability significantly influences the assessment of voltage sag.

Single Wire Earth Return (SWER) system voltage support using four quadrant DSTATCOM

open access: yes, 2016
Single Wire Earth Return (SWER) systems with long transmission line were introduced as one of the low cost options for remote electrification. Long transmission lines and load growth in such a system make voltage regulation a concern.

Coordinated voltage support strategy for heterogeneous reactive power resources in high wind power-penetrated systems

open access: yesFrontiers in Energy Research
In power systems with high-penetration wind farms (WFs) connected to a weak grid, insufficient system voltage support can lead to severe transient low/overvoltages under grid faults.

A Model Predictive Approach for Voltage Support in Microgrids using Energy Storage Systems

open access: yesIEEE Power & Energy Society General Meeting, 2021
Low voltage microgrid systems are characterized by high sensitivity to both active and reactive power for voltage support. Also, the operational conditions of microgrids connected to active distribution systems are time-varying.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
