Wind turbines, called variable-speed turbines, can be equipped with control features that regulate the power at high wind velocities. These variable-speed turbines can optimize power output without exceeding the turbine’s perforance limits. m Common variable-speed wind turbines include pitch-controlled, stall- controlled, and active stall-
