  • HVDC power transmission with cable fault ride-through capability
    Patent number: 8743514
    Abstract: A high voltage direct current (HVDC) power transmission system includes a cable fault ride-through system. The cable fault ride-through system is configured to ensure the HVDC power transmission system remains operational via an earth path between the power source end and the load end during a transmission cable fault, even in the absence of a neutral bus and/or dc circuit breakers.
    Type: Grant

  • System and method for controlling microgrid
    Patent number: 7983799
    Abstract: A system for controlling a microgrid includes microgrid assets and a tieline for coupling the microgrid to a bulk grid; and a tieline controller coupled to the tieline. At least one of the microgrid assets comprises a different type of asset than another one of the microgrid assets. The tieline controller is configured for providing tieline control signals to adjust active and reactive power in respective microgrid assets in response to commands from the bulk grid operating entity, microgrid system conditions, bulk grid conditions, or combinations thereof.
