Which of the following statements is/are FALSE concerning a wind turbine generation system?
- The rotor power coefficient, $C_{p}$, of a multi-blade turbine is a monotonically increasing function of tip-speed ratio
- Maximum power point tracking algorithms are typically employed in wind turbine generators for enhancing energy yield
- The theoretical maximum value of rotor power coefficient, $C_{p}$, is $0.65$
- Speed control of wind turbine generator is carried out to ensure rotor speed varies in response to wind speed
