Review of Key Technologies for Operation Control and Maintenance of Offshore Wind Farm

Offshore wind power is the focus of renewable energy development currently and in the next several decades. However, compared with onshore wind power, offshore wind power faces challenges such as higher LCOE through full life span and greater impact on grid. Digitization and intelligence are the keys to mitigate the above problems. To this end, this paper introduced the key technologies of intelligent operation, control, and maintenance of offshore wind farms, including offshore wind power forecasting, offshore wind power operation and control, offshore wind power equipment maintenance and management, and utilization of marine resources. Firstly, according to factors such as offshore weather, environment, wind resource, geographical location, turbine operation, etc., the differences between offshore wind power and onshore were analyzed. Based on this, the challenges and possible solutions faced by the above technical fields were summarized. The research status and achievements were also analyzed and summarized; finally, the development trend of the key technical fields of intelligent operation, control, and maintenance of offshore wind farms were pointed out. This review will provide support for cost reduction, efficiency increase of offshore wind farms as well as security and economics of power system when integrated by large-scale offshore wind power. © 2022 Chin.
