N2 - This paper studies the use of modular multi-level converter (MMC) in a HVDC transmission system. MMC, thanks to its robustness and high current quality and flexibility, has been widely used in HVDC transmission applications. However not many work is devoted to the area of MMC based HVDC system under unbalanced grid condition. This paper investigates a point to point MMC-HVDC system characteristics under unbalanced AC conditions. A model of a MMC converter is built under unbalanced conditions. Based on this model a control method, which controls positive- negative- and zero-sequence current components independently is proposed. A simulation case study is conducted to test the performance of the proposed controller.
