摘要：
The output current of the grid-connected new energy inverter often has the problem that the harmonics cannot reach the standard, and the harmonic interaction among inverters is complex, which brings new problems to harmonic responsibility evaluation. Firstly, the quantitative evaluation model of harmonic res-ponsibility is introduced. Then, the existing harmonic impedance estimation methods are classified and the applicable conditions of each method are clarified. Then the rationality of harmonic voltage evaluation index and other evaluation index is discussed. Based on the limitations of existing methods, the new harmonic characteristics and the new problems and difficulties of harmonic responsibility evaluation are discussed. Finally, the research of harmonic responsibility evaluation in the future is prospected. © 2020, Electric Power Automation Equipment Press. All right reserved.
