To integrate distributed generators (DGs) with the power grid, interfacing power converters such as voltage source converters (VSCs) are required. However, due to the switching natures, these converters generate harmonics, which may have detrimental effects on the system. To find out how these harmonics may interact with the grid, it is essential to find the admittance matrices of the converters. In this paper, the state‐of‐the‐art methods of modeling converters are thoroughly reviewed. Moreover, a new proposed method is also introduced, which can significantly increase the simulation efficiency. Finally, two numerical examples are presented. The results obtained by the proposed method are in great agreement with those of the state‐of‐the‐art methods and brute‐force time‐domain simulation such as PSCAD/EMTDC, demonstrating the validity of the proposed method. © 2014 Institute of Electrical Engineers of Japan.
