Abstract:
The future power system faces challenges of integrating more renewable power generations deploying more power electronic converters, and close interaction with communication and information technology. Control of renewable power generations and power electronic devices needs to deal with strong nonlinear dynamics and increased uncertainties, to provide better transient performance under various disturbances. This talk starts with a review of the characteristics and challenges of control and integration of wind turbines and then a review of the basic idea of disturbance estimation and compensation-based method, which can estimate the time-varying disturbances, including parameters uncertainties, modelling errors, and external disturbances, and how it can be used to improve the robustness of feedback linearization control and passivity based control. Applications of DFIG-based wind turbines and Static synchronous Compensators (STACOM) will be presented. Finally, how control systems can contribute to the transient performance of power electronic converters is illustrated with more examples.
