Abstract：The characteristics of inverter-based virtual synchronous generator (VSG) not only depend on control strate-gies but also are effected by the manner of equating and filter circuit. This paper focused on analyzing and studying comparatively performances of VSGs, which are in different equivalent modes and equipped with LCL filter circuits. Consequently, it was found that there are errors in the model established through regarding inverter and whole LCL circuit as synchronous generator (SG). Then, a method was proposed for modeling inverter based on VSG, by which the mathematical model built accurately describes the transient and steady characteristics of VSG-based inverter. The proposed method was verified by the comparison and analysis of simulation results.
