(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Applications such as multiphase machine drives and wind energy conversion systems are normally based on voltage source converters (VSCs) which feature a convenient and familiar control scheme. In high-power medium voltage ...
Active and reactive power management of photovoltaic-based interline dynamic voltage restorer in low voltage distribution networks
(
IEEE Computer Society
, 2012 , Conference Paper)
A dynamic voltage restorer (DVR) is a series connected device that can support the voltage at existing critical loads during voltage sags. Voltage restoration may need active and/or reactive power injection into the ...
