Hybrid ultra‐HVDC system with LCC and cascaded hybrid MMC
The Journal of Engineering, 2018 Nowadays, the hybrid high‐voltage direct current (HVDC) system consisting of line commutated converter (LCC) and modular multilevel converter (MMC) has become the most competitive candidate in multi‐infeed power systems. Owing to the limitation of insulated‐gate bipolar transistor's withstand voltage, the DC voltage rating of MMC is not compatible with
