This study is aimed to present a dynamic model for the voltage source converter‐based high‐voltage DC (HVDC). The multi‐modular converter (MMC) physical model is given and a linear control model for tuning the dynamic model is developed. MMC has a cascaded control structure, containing an outer loop and an inner loop. The reactive outer loop and the active outer loop could be designed and analysed independently. The average‐value model of MMC for electromechanical transient studies are given in this article. The average‐value model and detailed model are built in electromagnetic transient simulation program (PSCAD\EMTDC) to verify the validity, precision, and high speed of the proposed method.
