    Multiloop control strategy for grid-interfaced three-phase voltage source inverter with passively damped LLCL-filter 

    Azani, H.; Massoud, Ahmed; Ben-Brahim, L.; Williams, B.W.; Holliday, D. ( Institution of Engineering and Technology , 2014 , Conference)
    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. ...
