In this study, the three-phase four-wire shunt active power filter (ShAPF) dealing with non-ideal point of common coupling (PCC) voltages will be presented. The instantaneous power theory is applied to design the ShAPF controller which shows reliable performances. An adaptive notch filter (ANF) is proposed to process those unbalanced and/or distorted PCC voltage. The power balance among utility, load and ShAPF while applying ANF is clarified by an in-depth explanation. The simulation results prove that the ANF can successfully facilitate the ShAPF in terms of compensating unbalanced/distorted current of loads under a non-ideal PCC voltage circumstance.
