, 2013 , Conference Paper)
Inverters are considered the orbit of research objectives for safe and reliable grid interface. Amongst the conventional inverters known as suitable candidates for gird connection in the last two decades, Z-source inverter ...
A novel open-stator-winding DFIM flywheel architecture for renewable energy applications
(
IEEE
, 2013 , Conference Paper)
Energy storage is becoming a basic component of modern renewable power plants, especially wind farms. For several considerations, local wind turbine (WT) energy storage is preferred. Flywheel energy storage is among the ...
Brushless doubly fed induction machine as a variable frequency transformer
(
IEEE
, 2012 , Conference Paper)
Variable frequency transformer (VFT) has been recently used as an alternative to HVDC to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster ...
