Methods and systems for feedforward control of wind turbines

A system for constrained control of a wind turbine, the system comprising:

• a data acquisition unit configured to receive a plurality of operating parameters corresponding to the wind turbine, wherein the wind turbine is operated in a constrained parametric space and is controlled by a plurality of wind turbine control parameters, and wherein the plurality of operating parameters comprises a wind preview parameter and a plurality of constraint parameters;
• an extreme event management unit communicatively coupled to the data acquisition unit, wherein the extreme event management unit comprises:
• a wind propagation subunit configured to estimate one or more wind preview parameters at a future time instant;
• a constraint monitoring subunit configured to:
• generate a constraint parameter estimate at the future time instant corresponding to at least one constraint parameter among the plurality of constraint parameters based on the plurality of operating parameters and a wind preview model;
• predict an extreme event corresponding to the at least one constraint parameter based on the constraint parameter estimate and the constrained parametric space;
• a feedforward control subunit configured to determine a control parameter value corresponding to a wind turbine control parameter among the plurality of wind turbine control parameters based on the predicted extreme event;
• and
• a processor unit operatively coupled to the extreme event management unit and configured to operate the wind turbine using a feedforward control technique based on the control parameter value to circumvent the extreme event.

A non-transitory computer readable medium encoded with a program having instructions to enable at least one processor to:

• receive a plurality of operating parameters corresponding to the wind turbine, wherein the wind turbine is operated in a constrained parametric space and is controlled by a plurality of wind turbine control parameters, and wherein the plurality of operating parameters comprises a wind preview parameter and a plurality of constraint parameters;
• generate a constraint parameter estimate corresponding to a future time instant for at least one constraint parameter of the plurality of constraint parameters based on the plurality of operating parameters and a wind preview model;
• predict an extreme event corresponding to the at least one constraint parameter based on the constraint parameter estimate and the constrained parametric space;
• determine a control parameter value corresponding to a wind turbine control parameter among the plurality of wind turbine control parameters based on the predicted extreme event;
• and
• operate the wind turbine using a feedforward control technique based on the control parameter value to circumvent the extreme event.
