Real-Time Coordinated Control of Hybrid Energy Storage Systems for Floating Offshore Wind Turbine Power Quality Mitigation

The characteristic wind power generated by floating turbines includes significant low-frequency harmonics and lower efficiency compared to ideal wind turbine power curves. This implies that floating wind farms will face dual scrutiny regarding the adequacy of power quality and the matching of generated power output with dispatch commands. While optimization through energy storage systems remains one of the most common and effective solutions in wind farms, the achievement of optimal power output in the novel context of wind power from floating turbines necessitates the development of a new control system. With parameter-optimized design of Leveraging Kalman filters, a comprehensive HESS coordinated control scheme is proposed, integrating management of dispatch disparities and SOC health. Experimental data indicate that under the proposed Real-Time Coordinated Control (RTCC), the output power of floating offshore wind turbines (FOWTs) is significantly improved in quality and effectively matches dispatch commands. Additionally, suggestions are concluded for setting Kalman filter parameters for future multi-objective optimization challenges.
