摘要: In this paper, a novel current control technique, implemented in the a-b-c frame, for three-phase inverter is proposed to active and reactive power flow from renewable energy source generalized microgrid system. The system not only controls grid but also reduces total harmonic distortion presence of typical nonlinear loads. shapes taking into account voltage unbalance, harmonics as well unbalance line side inductors. stability ensured by direct method Lyapunov. A SRC improve performance controller estimating periodic disturbances (implemented digitally) provides superior over conventional multiple proportional-integral proportional-resonant methods due absence PARK's transformation blocks phase lock loop requirement structure. new modeling technique presented take care unbalances both voltages Experimental results are provided show efficacy
