Constrained power reference control for wind turbines

Daniel S. Zalkind et al.

Summary: By controlling the power reference of a wind turbine, energy capture can be increased while reducing generator speed and blade load transients. The controller increases power output under safe conditions and decreases it during problematic transient events, resulting in a 5% increase in annual energy production.

A synthesis of feasible control methods for floating offshore wind turbine system dynamics

Kamran Ali Shah et al.

Summary: Over the past decade, offshore wind energy development has shifted towards deeper waters, leading to the use of floating offshore wind turbines instead of traditional bottom-fixed turbines. However, the high cost of floating offshore wind turbines can be attributed to the inadequate adaptation of system dynamics control methods, affecting performance and reliability. Various control methods are systematically analyzed, with emphasis on wind and wave forecasting, to improve power maximization, regulation, and load mitigation in floating offshore wind turbine systems.
