DC array system refresh study

This is the summary report of an Offshore Wind Accelerator study into the feasibility of DC arrays as a means of connecting offshore wind farms. 

Rampion Offshore Wind Farm, United Kingdom

The use of medium voltage DC (MVDC) array cables rather than conventional 66kV or 33kV AC array cables to connect wind turbines to offshore substations has been a subject of ongoing research by academic and industry bodies looking at cost reduction opportunities for offshore renewables.

The Offshore Wind Accelerator (OWA) has undertaken a number of studies to track the potential opportunities of the technology over time. The first DC array system study took place in 2011. This executive summary provides an overview of the most recent work undertaken in 2018, highlighting the need for roadmaps to lay out the necessary steps to develop both commercial and technical capability to construct an offshore wind farm using DC arrays.
