Long-term voltage control

open access: yes, 2021
Long-term voltage control is aimed at maintaining the voltage magnitude of buses at the transmission and distribution levels within a given range and properly share the reactive power among available resources. Traditionally, longterm controllers are the voltage control of underload tap changer (ULTC) transformers that interface transmission and ...

Active Voltage Control (AVC) for Reducing Three-phase Voltage Fluctuations

open access: yesJournal of Applied Science and Engineering, 2023
The paper presents an active voltage compensator (AVC) to prevent voltage fluctuations on the load in both voltage’s rise and fall directions. This AVC is designed based on modeling a three-phase four-branch inverter according to the large-signal average

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
