However, the distance from future offshore wind farms (OWF) to the onshore grid can be more than 100 km, resulting in increased HVAC power loss and reactive power compensation requirement , which significantly reduces its economic benefits.
After parallel connection to an AC bus, the power is centralized to the AC/DC converter to be rectified again for HVDC transmission. However, it can be seen that this topology requires multiple AC transformers, which also increase the volume of offshore platform.
Offshore wind power (OWP) has developed rapidly in the past decades due to its high efficiency and zero carbon emission. In 2020, the yearly global OWP installed capacity was 6.1 GW , including 3.1 GW in China and 2.9 GW in Europe , which are the top two contributors.
According to the statistics in ref. , the cumulative global offshore capacity increased to more than 35.3 GW at the end of 2020. Furthermore, several countries had set higher offshore installation capacity targets by 2030, including 60GW for China , 40 GW for the United Kingdom , 20GW for Germany , and 28.1GW for the United States .
