Voltage control in low voltage distribution networks with high penetration photovoltaic system
(2017-12-01)
Photovoltaic generators can provide several benefits for distribution networks, such as power loss reduction, and improvements in voltage level. However, high penetration of these generators can cause voltage rise problems ...
Comparative analysis of current and voltage-controlled photovoltaic Maximum Power Point tracking
(2011-12-28)
Maximum Power Point tracking (MPPT) in photovoltaic (PV) systems may be achieved by controlling either the voltage or current of the PV device. There is no consensus in the technical literature about how is the best choice. ...
Multiloop controller and reference generator for a dynamic voltage restorer implementation
(2008-12-23)
This paper deals with the design and analysis of a Dynamic Voltage Restorer output voltage control. Such control is based on a multiloop strategy, with an inner current PID regulator and an outer P+Resonant voltage controller. ...

(2009-12-01)
The purpose of this work is to study voltage control and energy balance of a split DC bus topology within a power electronics equipment connected to the AC mains, such as UPS systems, wind power generators, active filters ...
Reference generator for voltage controlled power conditioners
(2011-12-28)
Voltage reference generation is an important issue on electronic power conditioners or voltage compensators connected to the electric grid. Several equipments, such as Dynamic Voltage Restorers (DVR), Uninterruptable Power ...
Estimation of Lost Voltage Measurements in Distribution Networks
(2014-09-08)
This paper presents an algorithm to estimate lost bus voltage measurements in balanced distribution networks regulated by centralized control schemes. The objective is to feed controllers with reliable estimations of lost ...
Real-Time Voltage Regulation in Power Distribution System Using Fuzzy Control
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
Two different fuzzy approaches to voltage control in electric power distribution systems are introduced in this paper. The real-time controller in each case would act on power transformers equipped with under-load tap ...
