Multi-terminal DC electrical network

A method of controlling power flow in a multi-terminal DC electrical network, the multi-terminal DC electrical network comprising:

• a plurality of DC terminals, each DC terminal being operatively connected to at least one other DC terminal via a respective DC power transmission medium;
• and
• a plurality of converters, each converter being operatively connected to a respective one of the DC terminals, the plurality of converters including at least one designated converter;
• wherein the method includes the steps of:
• (i) using an algorithm to process a plurality of values to thereby compute a no-load DC voltage for at least one first designated converter as a function of the plurality of values, the plurality of values including:
• at least one first value defining an operating mode of the or each designated converter;
• at least one second value defining a default electrical characteristic of the multi-terminal DC electrical network or a computation parameter of the algorithm;
• and
• at least one third value defining an electrical measurement corresponding to a voltage or current in the multi-terminal DC electrical network,
• (ii) operating the or each first designated converter in accordance with the or the respective computed no-load DC voltage.
