摘要：This paper deals with a converter control strategy for the integration of DG (Distributed Generation) to the power grid in presence of nonlinear load and unbalanced voltage condition. The proposed control scheme based on instantaneous power theory is investigated in the αβ stationary frame. This control scheme controls the current harmonic flow between the grid and the inverter in a way that the current harmonic distortion rate at the Point of Common Coupling (PCC) is compatible to IEEE standard. Simulation results using MATLAB/SIMULINK are presented for a 100 KW DG connected to the distribution grid via an inverter to confirm the validity and effectiveness of the proposed control scheme. Furthermore, a wind turbine unit, regarded as a DG unit, is simulated to evaluate the dynamic impact of distributed generation. Additionally, the reactive power compensation and the grid power factor correction are also achieved using this procedure.
