Abstract: The hybrid of AC and DC power grid and large-scale power transmission across regions have become main characteristics of power grid in China. As LCC-HVDC transmission lines are main structure of AC/DC hybrid power grid in China, to realize the fast and accurate simulation of AC/DC hybrid power grid, this paper analyzed and summarized existing modeling methods of LCC-HVDC converter. Advantages and disadvantages of these models were investigated, and suggestions for further research were proposed from the authors’ point of view: In the simulation of a large-scale AC/DC hybrid power grid, the LCC-HVDC can be modeled by switching function methods, but accuracy of the model needs to be improved; Simulation of multiple LCC-HVDC transmission lines can combine converter-level models with valve-level models; The data interfaces between different models should be optimized.
