Tracking maximum power point based on improved sliding mode for wind energy conversion systems

Tóm tắt

In the era of net zero emissions for nations worldwide, wind power energy conversion systems-which use clean and incredibly large wind energy reserves to generate electricity-have become popular. The generator of wind turbines is crucial to the process of converting mechanical energy into electrical energy, and because wind is unpredictable, a control system is required to monitor the maximum power of wind turbines. Therefore, in this study, a mode free (MFC) sliding mode control (SMC) is proposed to adhere to track maximum power point for the permanent magnet generator (PMSG) and the MATLAB simulation results are compared with linear quadratic regulator (LQR) to evaluate the working efficiency of the proposed controller applied to WECS.
