MULTI TERMINAL HVDC CONTROL
First Claim
1. A method of controlling a Multi-Terminal High Voltage Direct Current (MTDC) system with at least three terminals, each terminal including a Voltage Source Converter (VSC) controlled by a VSC controller, comprising:
- providing a converter schedule including at least one of a desired power flow value and a DC voltage;
determining, by a MTDC master controller, a present state of the MTDC system including a dynamic topology of the MTDC system;
determining, by the MTDC master controller, based on the present state of the MTDC system, based on the schedule and based on MTDC system constraints, VSC controller parameters including droop settings for local control by the VSC controllers; and
transmitting the VSC controller parameters to the VSC controllers.

Abstract
An exemplary Multi-Terminal High Voltage Direct Current (MTDC) system includes at least three terminals, where each terminal including a Voltage Source Converter (VSC) controlled by a VSC controller. A method for controlling the MTDC system includes providing a converter schedule including at least one of a desired power flow value and a DC voltage; determining, by a MTDC master controller, a present state of the MTDC system including a dynamic topology of the MTDC system; determining, by the MTDC master controller, based on the present state of the MTDC system, based on the schedule and based on MTDC system constraints, VSC controller parameters including droop settings for local control by the VSC controllers; and transmitting the VSC controller parameters to the VSC controllers.
