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 ...
A synchronous DQ frame controller via an LCL coupled filter under unbalanced three-phase voltage supply conditions
(
IEEE
, 2011 , Conference Paper)
This paper proposes a synchronous DQ frame current controller for inverter based interfaced systems. The grid voltage may be unbalanced, possibly due to unequal line impedance. The output active and reactive powers oscillate ...
