COORDINATED CONTROL OF MULTI-TERMINAL HVDC SYSTEMS
First Claim
1. A method for controlling a multi-terminal HVDC system having a plurality of converter stations, the method comprising:
- receiving a plurality of measurements from a plurality of measurement units disposed on the HVDC system;
identifying from the measurements a disruption within the HVDC system;
monitoring the measurements to identify a steady-state disrupted condition for the HVDC system;
calculating 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 disrupted condition and the measurements; and
transmitting the new set point to the at least one of the plurality of converter stations.

Abstract
Multi-terminal HVDC systems and control methods therefore are disclosed. Methods for controlling multi-terminal HVDC systems having a plurality of converter stations may include receiving a plurality of measurements from a plurality of measurement units disposed on the HVDC system, identifying from the measurements a disruption within the HVDC system, monitoring the measurements to identify a steady-state disrupted condition for the HVDC system, calculating a new set point for at least one of the plurality of converter stations, which new set point may be based on the steady-state disrupted condition and the measurements, and transmitting the new set point to the at least one of the plurality of converter stations. In some examples, the HVDC systems may include an HVDC grid interconnecting the plurality of converter stations and a controller communicatively linked to the plurality of measurement units and the plurality of converter stations.

19. 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. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
