Abstract

Power generation through wind is expected to play a major role in the world's future energy portfolio. Wind power integration remains a challenging research area due to the unique characteristics of wind power generation. In particular, offshore wind has received significant attention worldwide due to the vast generation potential available. The electrical infrastructure of offshore wind farms is thus of significant importance. Multi-terminal high voltage direct current (HVDC) technology represents a preferable solution and has shown promise in solving wind farm interconnection problems. Droop control techniques have been proposed as a means to regulate the DC voltage and facilitate the automatic coordination between different converters without the need for fast communication between units. Different methodologies have been suggested to select the droop gains to satisfy the system performance specifications. In this work, a control design methodology is proposed for power sharing among the multi-terminal HVDC feeders providing that the power transmission efficiency is optimized. A simulation study on a 400 kV/1000 MW four-terminal HVDC transmission topology is conducted to determine the validity of the proposed methodology.
