Assessment of the operating conditions of coordinated Q-V controller within secondary voltage control system [PDF]

open access: yesZbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2014
The paper, discusses the possibility to use coordinated Q-V controller (CQVC) to perform secondary voltage control at the power plant level. The CQVC performs the coordination of the synchronous generators' (SG) reactive power outputs in order to ...

Options for Control of Reactive Power by Distributed Photovoltaic Generators [PDF]

open access: yes, 2010
High penetration levels of distributed photovoltaic(PV) generation on an electrical distribution circuit present several challenges and opportunities for distribution utilities. Rapidly varying irradiance conditions may cause voltage sags and swells that

Can Distribution Grids Significantly Contribute to Transmission Grids' Voltage Management?

open access: yes, 2016
Power generation in Germany is currently transitioning from a system based on large, central, thermal power plants to one that heavily relies on small, decentral, mostly renewable power generators.

Optimal Distributed Feedback Voltage Control Under Limited Reactive Power [PDF]

open access: yesIEEE Transactions on Power Systems, 2018
In this paper, we propose a distributed voltage control in power distribution networks through reactive power compensation. The proposed control can operate in a distributed fashion where each bus makes its decision based on local voltage measurements ...

Demonstration of sustained and useful converter responses during balanced and unbalanced faults in microgrids [PDF]

open access: yes, 2012
In large power grids where converter penetration is presently low and the network impedance is predominantly reactive, the required response from converters during faults is presently specified by phrases such as “maximum reactive output”.

On Variable Reverse Power Flow-Part I: Active-Reactive Optimal Power Flow with Reactive Power of Wind Stations

open access: yesEnergies, 2016
It has recently been shown that using battery storage systems (BSSs) to provide reactive power provision in a medium-voltage (MV) active distribution network (ADN) with embedded wind stations (WSs) can lead to a huge amount of reverse power to an ...

Elaboration and characterization of Fe1–xO thin films sputter deposited from magnetite target [PDF]

open access: yes, 2007
Majority of the authors report elaboration of iron oxide thin films by reactive magnetron sputtering from an iron target with Ar–O2 gas mixture. Instead of using the reactive sputtering of a metallic target we report here the preparation of Fe1–xOthin ...
