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. ...

Mnltiloop Controller and Reference Generator for a Dynamic Voltage Restorer Implementation
(IEEE, 2008-01-01)
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. ...
Resonant (P+RES) controller applied to voltage source inverter with minimum DC link capacitor
(2011-12-28)
Voltage source inverters use large electrolytic capacitors in order to decouple the energy between the utility and the load, keeping the DC link voltage constant. Decreasing the capacitance reduces the distortion in the ...
