Coordinated voltage control for improved power system voltage stability by incorporating the reactive power reserve from wind farms

Frontiers in Energy Research, 2023
The absorption and output characteristics of reactive power of the doubly-fed induction generator (DFIG) greatly influence the voltage stability of PCC (Point of Common Coupling) where the wind farms are integrated into the bulk power grid.

Quasi-independent voltage-reactive power zone controller

2017 IEEE Manchester PowerTech, 2017
In this paper the zone controller is presented which regulates the reactive power-voltage characteristic (Q-V) of the zone pilot node by altering the reactive power outputs of power plants within the zone. As far as the zone is self-sufficient regarding reactive power needs, the generation is adapted to fit consumption and quasi-independent operation ...

Research on Reactive Power Coordination Control of Urban Rail Transit Power Monitoring System

Chengshi guidao jiaotong yanjiu
[Objective] The power supply system of urban rail transit mainly relies on the SVG (static var generator) or reactors in the 110 kV main substation for centralized reactive power compensation. The current control mode does not fully consider the reactive

Instantaneous Reactive Power Theory Control Scheme for Reactive Power Compensation using DSTATCOM

International Journal of Recent Technology and Engineering (IJRTE), 2020
Distribution static compensator is a well known facts device which control reactive power flow in a distribution system. Nowadays major loads in distribution system are inductive loads, which will consume more reactive power. In order to improve power quality, this paper developed an IRPT control scheme for generating the reference quantity components ...

A Hybrid Reactive Power Control Method of Distributed Generation to Mitigate Voltage Rise in Low-Voltage Grid

, 2020
A high penetration of distributed generators, such as solar and wind power generators in low voltage network systems, impose voltage rise problems. Reactive power control of distributed generators can contribute to mitigating the voltage rise.

Intravitreal GD2‐Specific Chimeric Antigen Receptor T‐Cell Therapy for Refractory Retinoblastoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Effective treatments for advanced, treatment‐resistant retinoblastoma (RB) remain limited. GD2‐specific chimeric antigen receptor (CAR) T cells show potent antitumor activity with minimal toxicity but have not previously been evaluated in RB.

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
