Accurately dividing the harmonic impact of each harmonic source on the PCC bus is an important prerequisite for implementing the ‘reward and punishment scheme’. At first, the equivalent circuit model of multi-linear load harmonic source in PCC bus is obtained by using circuit theory, and the method of quantifying the harmonic impact for multi-harmonic sources is derived. Secondly, the M-estimated robust regression method is introduced into quantifying the harmonic impact for multi-harmonic sources. The method uses the iteratively weighted least squares iterative method to solve the regression coefficients, and calculates the harmonic impact of each harmonic source in the multi-harmonic source system according to the regression coefficient. In order to verify the effectiveness of the method, the simulation analysis is carried out in the power system analysis software ETAP. The results show that the method can effectively evaluate quantifying the harmonic impact for multi-harmonic sources.
