doi:10.3969/j.issn.1008-0198.2025.05.007

Abstract

Abstract: To enhance the economy of offshore wind power and make fuller use of offshore wind power resources, high-voltage direct current transmission and DC aggregation technologies related to offshore wind power DC transmission is proposed. Combining different connection methods and different system boosting times, the topology of offshore wind power DC aggregation and boosting is selected to meet the current development trend of offshore wind power, and the characteristics of each topology in the DC aggregation system under typical offshore wind power scenarios are analyzed. The construction cost, energy loss and reliability of each topology are studied in conjunction with typical case studies. Finally, the most suitable DC aggregation scheme configuration for large-scale offshore wind farms is then derived to improve the comprehensive benefits of the offshore wind power DC aggregation system.

Key words: offshore wind power, DC aggregation and boosting system, topology, economy, energy loss, reliability
