Multiloop control strategy for grid-interfaced three-phase voltage source inverter with passively damped LLCL-filter
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
In inverter-based distributed generation (IBDG) and similar to the conventional third order LCL filter, the high order LLCL filter is difficult to stabilize, and may cause a resonance between the inverter and the grid. ...
Maximum Power Transfer Of Pv-fed Inverter-based Distributed Generation With Improved Voltage Regulation Using Flywheel Energy Storage Systems
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
One of the main issues accompanied with the high penetration of PV distributed generation (DG) systems in low voltage (LV) networks is the overvoltage challenge. The amount of injected power to the grid is directly related ...
