A voltage-source inverter for microgrid applications with an inner current control loop and an outer voltage control loop [PDF]

open access: yes, 2009
Distributed generation (DG) units are commonly inter-faced to the grid by using voltage-source inverters (VSI’s). Extension of the control of these inverters allows to improve the power quality if the main power grid is disturbed or disconnected. In this

Embedded control system for reactive power control in distributed energy resources for voltage regulation in the distributed power system [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2023
Since more distributed energy resources (DER) are being linked to the electrical grid, the current distributed power system (DPS) is encountering additional voltage regulation challenges.

Lack of direct evidence for a functional role of voltage-operated calcium channels in juxtaglomerular cells [PDF]

open access: yes, 1990
In this study we have examined the role of voltage-gated calcium channels in the regulation of calcium in juxtaglomerular cells. Using a combination of patch-clamp and single-cell calcium measurement we obtained evidence neither for voltage-operated ...
