Delayed-signal cancellation with multiple notch filters (DSC-MNFs) is proposed for harmonic elimination to extract the fundamental active and reactive powers.
The proposed MCA for load fundamental active current can be expressed as: bar{i}_{text{Sd}} = frac{{bar{u}_{text{Ld}} }}{{bar{u}_{text{Sd}} }}bar{i}_{text{Ld}} (21).
To deal with unbalanced loads, this paper proposes a matching-ratio compensation algorithm (MCA) for the fundamental active component of load currents, and by employing this MCA, balanced three-phase grid currents can be realized under 100% unbalanced loads.
