Same as HVDC infrastructure, this technique is also based on the electrical interconnections. It is in its infancy; however, using this technique, the industry can get rid of the other half of the conventional turbine power conversion system which converts back to grid‐frequency alternating current (AC). This technique saves the capital cost and enhances reliability. By shifting towards DC collection, the array of cable cores decreases to two from three and the amount of material also reduces by 20–30% (IRENA 2016). Progression of this technique is happening at a slower rate due to non‐acceptance of higher‐voltage AC array cables by the industry.
