Currently, Maximum Power Point Tracking (MPPT) is the system used to control the rotational speed of a wind power system. MPPT control that follows the rotational speed that can obtain the maximum power for that wind speed. However, under wind conditions in regions with large wind speed fluctuations, it is difficult to quickly control the rotational speed of large wind turbines with large inertia. The effect is to reduce the power output by up to 40% at most. In this study, RSM (Rotation-SpeedMaintenance) control is verified as a control algorithm for increasing the amount of electricity generated in situations with large wind speed fluctuations. The RSM control focuses on maintaining the rotational speed. RSM control tracks the optimum rotational speed in the same way as MPPT control, but RSM control maintains a higher rotational speed. By maintaining a high rotational speed, high wind speeds are efficiently converted to power in situations with large wind speed fluctuations. Furthermore, RSM control increases the input torque, thus improving acceleration control. MPPT control and RSM control are compared under the same conditions. The effectiveness of RSM control is verified via simulations.
