Abstract Focusing on the issue of harmonic distortion in the low-voltage distribution network with multiple feeders,this paper buildsa distributed active filtering system with multifunctional photovoltaic inverters working as the basic units.By modeling and analyzing the harmonic resources,the positive effect of harmonic voltage on the point of common coupling (PCC)can be utilized rationally.Under the consideration of capacity limitation of the multifunctional inverts,a multiple objectivefor harmonic suppression is developed,which canachieveanoptimized allocation of harmonic compensation for each distribution feeder.Subsequently,the characteristics of different harmonic compensation strategies are compared by Matlab/Simulink and the simulation results verify the effectiveness of the proposed strategy.Compared with existing harmonic filtering system,the proposed distributed active filtering system optimizes the effect of harmonic suppression on PCC and reduces the capacity for harmonic compensation at the same time.
