A large number of nonlinear components exist in AC/DC hybrid microgrid, which will cause harmonic pollution and affect power quality. In this paper, according to the diversity, complexity, nonlinear and mutation characteristics of harmonics, the harmonic analysis of AC/DC hybrid microgrid is carried out by adding harmonic sources. The model diagram of AC/DC hybrid microgrid is built, and the mathematical parameters of harmonics are introduced. Finally, the simulation of microgrid model is constructed based on ETAP, and the harmonic characteristics of AC/DC hybrid microgrid are studied in three cases of static load and equivalent grid using the same harmonic source.
