  • Operation and control of hybrid HVDC system with LCC and

    The operation modes of the proposed hybrid HVDC system are very flexible. In addition to the complete hybrid operation mode, the system could operate in the VSC‐HVDC (or LCC‐HVDC) mode when the LCC (or VSC) link is under scheduled maintenance. Moreover, the proposed hybrid topology is able to operate even with one LCC or one VSC out of service.
