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. ...
