Exploiting voltage support of voltage-source HVDC
IEE Proceedings - Generation, Transmission and Distribution, 2003The inherent voltage support in voltage-source converters (VSCs) which form a back-to-back VSC–HVDC asynchronous link can increase the power transmissibility by a factor of 1.68 if the installation is sited at the midpoint of the radial AC transmission line.

Voltage support cost allocation
Energy Conversion and Management, 2011In restructured power system the main task of the system operator is to run the system with security and reliability. To maintain system security, the voltage at all the nodes must always be maintained within limits, for which system must be supported by sufficient amount of reactive power. The generators will be interested in delivering reactive power

Error Analysis for the Support of Robust Voltage Scaling
Sixth International Symposium on Quality of Electronic Design (ISQED'05), 2005Recently, a new dynamic voltage scaling (DVS) scheme has been proposed that increases energy efficiency significantly by allowing the processor to operate at or slightly below the minimum supply voltage, even if occasional errors result. To determine which technique can reliably and efficiently detect such failures, it is necessary to understand the ...

Decentralized Voltage Support in a Competitive Energy Market
2019 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2019In order to facilitate the increasing amount of distributed generations and flexible loads, it is envisioned that the future power grid might operate in a more decentralized manner. To this end, this work proposes a decentralized market framework for multiple interconnected microgrids which can exchange energy and provide voltage support.

Decentralized voltage support in a Low Voltage feeder by droop based voltage controlled PVs
2013 Australasian Universities Power Engineering Conference (AUPEC), 2013Voltage drop at network peak hours is a significant power quality problem in Low Voltage (LV) distribution feeders. Recently, voltage rise due to high penetration of Photovoltaic cells (PVs) has been creating a new power quality problem during noon periods.

Reactive power control for voltage support during type C voltage-sags
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012Grid faults are one of the most severe perturbations to deal with in grid connected systems. To support the grid under voltage-sags (dips), different reactive power control strategies are needed depending on the type of grid fault. One of the possible objectives when supporting the grid voltage under type C voltage sags could be to avoid undervoltage ...

Voltage Sensitivity Analysis in Voltage Support of the China Southern Power Grid
2006 International Conference on Power System Technology, 2006Supply support in receiver system can improve the stability of the system, especial voltage stability. As the receiver system in the China Southern power grid (the CSG), Guangdong Province's load is 70% of the CSG. The voltage support should be applied to improve stability. In this paper, many operation schemes are simulated.

Optimal voltage support and Stress Minimization in power networks
2015 54th IEEE Conference on Decision and Control (CDC), 2015A standard operational requirement in power systems is that the voltage magnitudes must lie within pre-specified bounds. Conventional wisdom suggests that such a tightly regulated voltage profile should also guarantee a secure system, operating far from static bifurcation instabilities such as voltage collapse.

Voltage Support Provided by a Droop-Controlled Multifunctional Inverter
IEEE Transactions on Industrial Electronics, 2009This paper presents a single-phase multifunctional inverter for photovoltaic (PV) systems application. The converter provides active power to local loads and injects reactive power into the grid providing voltage support at fundamental frequency. The proposed topology is controlled by means of the droop-control technique. Hence, it allows the obtaining
