Abstract:
In this paper a control technique for renewable energy resourcesgrid interface is proposed based on extended multi output-recursive least square (EMO-RLS) algorithm considering active power management and harmonic, unbalanced and reactive current components elimination. The proposed method is evaluated via MATLAB/SIMULINK software. Firstly, an artificial three-phase unbalanced harmonic signal is generated. It will be transmitted to different estimators for their outputs comparison. The results indicate proper performance of the suggested structure for active harmonic symmetrical components analysis in comparison with the other traditional methods. Also, its dynamic operation in tracking of load current variations is evaluated employing EMORLS algorithm for control system of a DG source interface. It illustrates the active power injection to the grid is managed, as well as the harmonic, unbalance and reactive current components, are decreased simultaneously.
