Abstract To calculate the harmonic power flow of the distribution network with large-scale distributed grid-connected inverter, this paper first establishes the harmonic source model based on the grid-connected control strategy and modulation mode of inverters, then establishes the harmonic network according to the parameters and harmonic frequency of the distribution network so as to calculate the high-order harmonic power flow in the distribution network. The accuracy and practicability of the proposed method are verified by the simulation results of Matlab/Simulink platform for a distribution network model with multiple distributed grid-connected inverters.
