Investigation of inter-line dynamic voltage restorer with virtual impedance injection
(
IEEE
, 2010 , Conference Paper)
The Inter-Line Dynamic Voltage Restorer (IDVR) consists of several voltage source inverters connected to different independent distribution feeders with common dc bus. When one of the inverters compensates for voltage sag ...
An active damping technique for a current source inverter employing a virtual negative inductance
(2010 , Conference Paper)
A grid connected CSI requires a CL filter stage. In this work, the isolation transformer leakage inductance constitutes this filter inductance. This CL filter is lightly damped for efficiency constraints. Hence, it is ...
Inverter-based versus synchronous-based distributed generation; Fault current limitation and protection issues
(
IEEE
, 2010 , Conference Paper)
The contribution of distributed generation (DG) to network fault levels depends heavily on the technology employed. In the case of directly connected rotating machines the fault behavior is well established; with synchronous ...
New voltage regulation techniques for low voltage radial feed PWM inverter based distributed networks
(2010 , Conference Paper)
Grid voltage rise problems occur, especially at light loads, due to the proliferation of distributed generation. Two techniques are proposed for regulating the voltage in low voltage radial networks when inverter based ...
