Voltage Unbalance Compensation in Distribution Feeders Using Soft Open Points

Journal of Modern Power Systems and Clean Energy, 2022
Soft open points (SOPs) are power electronic devices that may replace conventional normally-open points in distribution networks. They can be used for active power flow control, reactive power compensation, fault isolation, and service restoration ...

Coordinated LVRT Support for a PMSG-Based Wind Energy Conversion System Integrated into a Weak AC-Grid

Energies, 2021
In a grid, the choice of the point of common coupling (PCC) does not solely rely on the voltage level alone but also conjointly depends on the grid strength for many explicit purposes.

In vivo Dominant-Negative Effect of an SCN5A Brugada Syndrome Variant

Frontiers in Physiology, 2021
Loss-of-function mutations in the cardiac Na+ channel α-subunit Nav1.5, encoded by SCN5A, cause Brugada syndrome (BrS), a hereditary disease characterized by sudden cardiac death due to ventricular fibrillation.

Power-Based Concept for Current Injection by Inverter-Interfaced Distributed Generations during Transmission-Network Faults

Applied Sciences, 2021
This paper analyzes the influence of inverter-interfaced distributed generations’ (IIDGs) response during transmission network faults. The simplest and safest solution is to switch IIDGs off during network faults without impacting the network voltages. A

A study on the negative sequence current injection during LVRT of IBRs

RE&PQJ
Low Voltage Ride Through (LVRT) behaviour of Inverter Based Resources (IBR) during asymmetrical grid faults is dictated by the requirements of Grid Code (GC) at the Point of Common Coupling (PCC) of the renewable energy plants. Earlier GCs demanded only positive sequence current injection, which gave freedom to inverter manufacturers to implement ...

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.
