Coordinated control of multi-terminal hvdc systems

A computer readable storage medium having embodied thereon a plurality of machine-readable instructions configured to be executed by a computer processor to control a multi-terminal HVDC system that has a plurality of converter stations, the plurality of machine-readable instructions comprising instructions to:

• receive a plurality of measurements from a plurality of measurement units disposed on the HVDC system;
• identify from the measurements a disturbance within the HVDC system;
• monitor the measurements to identify a steady-state disturbed condition for the HVDC system;
• calculate a new set point for at least one of the plurality of converter stations, wherein the new set point is based on the steady-state disturbed condition and the measurements;
• and
• transmit the new set point to the at least one of the plurality of converter stations.

A multi-terminal HVDC system, comprising:

• a plurality of converter stations;
• an HVDC grid interconnecting the plurality of converter stations;
• a plurality of measurement units disposed within the HVDC system, wherein the measurement units are configured to obtain a plurality of time-tagged measurements from the HVDC system;
• and
• a controller communicatively linked to the plurality of measurement units and the plurality of converter stations, wherein the controller is configured execute instructions to:
• receive the measurements from the plurality of measurement units;
• identify from the measurements an outage within the HVDC system;
• monitor the measurements to identify a steady-state outaged condition for the HVDC system;
• calculate a new set point for at least one of the plurality of converter stations, wherein the new set point is based on the steady-state outaged condition and the measurements;
• and
• transmit the new set point to the at least one of the plurality of converter stations.
