A Centre Resonance Mitigation Strategy for Clustered Grid-connected PV Inverters Based on Hybrid Active Damper
In order to deal with resonance problem caused by the access of clustered PV inverters, this paper proposes a resonance mitigation control strategy based on hybrid active damper.. Then, the proposed strategy only added harmonic conductance in resonance frequency using the resonance detection method. Meanwhile, the proposed control strategy also introduced quasi PR control to overcome the challenges caused by the filter capacitor. Finally, the effectiveness of the proposed control strategy is validated in Matlab/Simulink.
