Abstract

All-DC offshore wind power system represents a highly viable approach for the transmission of electricity over extended distances with high capacity. This paper proposes a novel DC collection topology employing a series-parallel connection among wind turbines for application in all-DC offshore wind power systems. This DC collection topology is particularly well-suited for the energy transfer from high-capacity wind turbines, enabling the entire wind farm to attain maximum power point tracking. Furthermore, a state-space small-signal model for the proposed DC collection configuration is developed, and eigenvalue trajectories are analyzed to ensure precise stability assessment. Finally, the efficacy and advantages of the proposed DC collection configuration are validated through simulation tests.
