Original abstract
This study suggests a voltage stabilization control technique for wind power generation systems based on an enhanced maximum power tracking algorithm in order to address the issues of maximum power tracking hysteresis and DC-bus voltage instability in wind power generation systems under wind speed fluctuations. The study first develops an adaptive perturbation search-based maximum power tracking technique. By dynamically adjusting the speed search step size and direction, it effectively overcomes the tracking lag and power oscillation problems of traditional methods under variable wind speeds. Then, the study proposes a sliding mode control strategy for integrated supercapacitor energy storage. By designing a sliding mode surface containing an integral term and an improved reaching law, the charging and discharging of the energy storage are coordinated to quickly compensate for the power difference and suppress voltage fluctuations. The simulation outcomes revealed that the tracking accuracy of the suggested improved maximum power tracking algorithm reached 98.7%. The proposed voltage stabilization control method could limit the maximum deviation of the DC-bus voltage to within 5.5 V, and the voltage overshoot was only 2.8% at a wind speed of 12 m/s. Moreover, the average voltage recovery time and supercapacitor power response time were shortened to 95.8 ms and 12.6 ms, respectively. The findings demonstrate that the suggested approach can enhance the system’s dynamic performance and power quality while achieving effective maximum power tracking and quick voltage stability control. For wind power systems operating in highly fluctuating conditions, this offers a workable approach for voltage stabilization.
